The Chairman and Members, The Greater Winnipeg Mosquito Abatement District. Gentlemen : On behalf of the Executive Committee I present this Sixth Annual Report of the Greater Winnipeg Mosquito Abatement District for the year ended December 31st, 1959. Before commenting on the District's operation, it is with regret that I record the passing away of two valued and appreciated employees-Mr Edmund John Stansfield, February 25th, 1959, and Ernest Schultz, January 20th, 1959. Mr Stansfield was long associated with the organization andl was appointed Field Manager in 1950. His cordiality and manifold virtues can but be inadequately expressed. Mr Schultz was engaged in mosquito control work since 1943 and his devotion to duty ·is acknowledged. On March 1st, 1959, Mr Peter Belski, former Assistant to the late Mr. Stansfield, was appointed Acting Field Manager and confirmed as permanent on June 1st, 1959. The able performance of his responsibilities during his first year as Field Manager confirmed the recommendations and confidence placed in him in his previous years of employment. At the Regular Meeting of the Board held in March 1959 approval was given to preliminary plans for the construction of an office and garage building. The District availed themselves of the services of the Design Branch of the City of Winnipeg, Engineering Department. Due to the heavy construction program, detailed plans andl specifications will not be proceeded with until 1960. The building will be ready for occupancy in mid-summer 1960. The Executive Committee recognizes the need for more public r elations . The acquainting of the public with the District's control measures in relation to conditions, the limitations of equipment and facilities in relation to area under control (250 square miles) the continued search by the Technical Advisory Committee for the most positive method of control ; the experiences of other Mosquito Abatement Districts and the World H ealth Organization in their fight Three against this prolific invader all over the world. The Executive Committee is confident progress is being made and I quote 'in part the follow'ing from the report of the Chairman of the Technical Advisory Committee; Professor A. J Thorsteinson "The records once again show dearly that mosquito numbers are much larger a short distance outs ide the District" Through a concerned approach to approved budget and with no addition to the mechanical force the District ended the year with a surplus of $38,225 .89, including reserves of $25,800.00, well within the limitations as set out in the Act. The resultant amount of $12,425.89 and reduced requirements in 1960 for building construction and property development will make available more fundls for control measures. In conclusion, I wish to express my appreciation for interest shown and co-operation given by member municipalities , by Members of the Board, by individuals, and by firms . FIELD MANAGER'S REPORT P BELSKI- Field Manager The heavy snow fall of 1958-1959 and 9 inches of rain from April 1st to July lOth, 1959, left extensive areas of flooded and wet land. The hatching of mosquito larvae began April 13th, andl was practically continuous till September 15th, 1959. To control adult mosquitoes that hatched in the control area or flew in from outside, it was n ecessary be tween June 18th and August 19th, 1959, to fog the streets and lanes of the built up areas of Greater Winnipeg four times, w'ith additional protection given to the parks and certain open air public gatherings. Larviciding Survey work started the firs t week in April. The first larvae were found on April 13th. Larval control was carried on as follows: 1. Five men used hand equipment to spray DDT from April 13th to September 15th, 1959, a total of 3,729 man hours . THE WINNIPE.G BOARD OF PARKS AND RECREATION, for Field Headquarters at the Stores Department and locations for three mosquito traps at the main parks. 2. Four men operated the two Aero-Mist Power Blowers from April 13th, to June 17th. Trucks travelled 2,742 miles while spraying. THE CITY OF WINNIPEG ENGINEERING DE.P ARTMENT for storage space for five trucks and three oil tanks. Pre-Season Control THE SURVEY DE.PARTMENT of the City of Winnipeg for assistance rendered. THE POLICE DEPARTMENTS, in all municipalities, for nightly co-operation when fogging. THE TECHNICAL ADVISORY COMMITTEE, for attendance at m eetings and advice given. LOCAL NEWSPAPERS and broadcasting stations. On the advice of the Technical Advisory Committee it has been decided to continue pre-season control. 1. In the fall of 1959, 4,639 acres of swamp land were sprayed with 1.1 lbs. DDT per acre, using two four-wheel drive Dodge Power Wagons, with AeroMist blowers. This will control breeding places in the spring and summer of 1960. 2. In the winter of 1959-60, 9,000 acres of bush land have been mapped to be treated w'ith 30% DDT in Vermiculite, application is one lb. DDT per acre. This work will •b e done early in the new year using a Piper Cub aeroplane. HARBOUR PATROL, for advice on river conditions. WEATHER OFFICE at Winnipeg Airport, for daily forecasts. Fogging DEPARTMENT OF ENTOMOLOGY, University of Manitoba, for advice and use of equipment. Fogging again showed its importance in protecting residential areas, gardens, parks and playgrounds from adult mosquitoes. Six Tifas and! two Swing-fog machines used 7% DDT oil solution for this control. On the following pages appear more detailed reports from the Officers of the District, together with Auditor's Certificate and Financial Statement. 1. Five Tifa foggers started adulticiding June 18th, and continued to August 19th, 1959. The trucks travelled 6,591 miles while fogging. Respectfully submitted, J K. CRABB, Chairman. FouT 2. Two Swing Fogs were used to adulticide places that wer e inaccessible to trucks or boat and started June lOth, and continued to August 28th, 1959, a total of 636 hours. Five 3. The mosquito boat, "Harry M" travelledl 354 miles while fogging the river banks on both sides of the Red, Assiniboine and Seine Rivers. Fogging the rivers started July 14th and continued to August 19th, 1959. City and Municipal Police are notified each night of the route to be taken by fogging machines . Families throughout Greater Winnipeg, who ask for this service, are also notified at 11.00 p.m., to expect the fogger that night. Top Minnows ( Gambusia affinis) On Miay 23rd, 1958, fifty of these minnows were placed in a pond in King's P ark. By November 1958, there were several thousand of all sizes. About one thousand minnows were taken from this pond late in the fall and transferred to the trout hatchery at Caddy Lake for the winter 1. Then came the big test. On January 6th, 1959, a check on the pond at King's Park was made under seven inches of ice, there were no fish found. Then later the trout hatchery reported that no Gambusia minnows survived the winter. The 1958-59 winter was one of the coldest in years. Insecticides On May 17th, 1959, R. Brust, B.S.A., and J MacTavish, B.A., the two University students assisting in mosquito work, wandered over to the pond in King's Park and saw Gambusia minnows. When the two students reported back to the University they had enough live Gambusia with them to prove the fish can survive a winter here. We now have Gambusia minnows in eight ponds in and around Greater Winnipeg, we intend to place more in other ponds. Night Fogging is necessary for the following reasons: Lower wind speed at night does not blow the DDT fog away too quickly 2. Lower temperature at night allows the fog to stay low 3. Mosquitoes are more active at night and therefore more vulnerable to DDT 'I1raffic on the streets is at a minimum and the hazard of interference b y children is avoided!. DDT was used in the form of oil solution, water emulsion and in 30 % DDT vermiculite granules. Special Requests New J ersey Larvicide, a Pyrethrin mixture, was used in an oil fog for quick knock down of flying mosquitoes, and for a larvicide in the vicinity of cattle and poultry ranches. This was found to be effective in killing both larvae a nd pupae of mosquitoes. The District has received many requests from public andl private organizations and individuals for special fogging or spraying for outdoor picnics, parties, parks, etc. Mosquito Bombs, for larviciding, contain DDT and Lindane inside a capsule. These were used by the district and supplied free to municipalities applying for them, including· Boy Scout and Girl Guide outings, service clubs, parks, and community clubs were done, provided such work did not interfere with routine work to protect entire communities. Private parties were referred to private contractors who are equipped to do such work. Brooklands Charleswood East Kildonan East St. Paul North Kildonan St. Boniface Old Kildonan St. James Tuxedo Winnipeg Drainage Two hundred and eighty-eight man hours of work were used in cleaning culverts, cutting willows out of ditches to allow free drainage and ease of spraying. Housing and industrial developments have drained many acres of low land. However new developments spread out towards other breeding grounds that must now be sprayed. Additional built-up areas have to be protected. Fogging operations have to be extended and new problems arise. Those seeking advice as to how they could spray their own premises were given necessary information . Visitors to the District Dr. M.

J THORSTEINSON Chairman University of Manitoba, Department of Entomology In this third year of operation of the Mosquito Survey and Investigations Project we have arrived at a stage where our records provide a contrasting picture of the variability of mosquito incidence from year to year For example, there were four peaks of mosquito activity in 1957 only two in 1958 but in 1959 there were six more noticeable peaks and three or more smaller p eaks. In each year there was one major peak which oc~urred during July in 1957 and 1958 but in 1959 it arrived one month earlier These variations are of course correlated with the pattern of heavy rainfall and favourable mosquito breeding conditions. Our Mosquito Breeding Survey provides information that enables us to predict the larger outbreaks some days in advance and in the future this will enable the field crews to switch over from larviciding to fogging operations in good time. The records once again show clearly that mosquito numbers are much larger a short distance outside the District and we attribute the protection achieved inside the District to the larviciding operations both with DDT granules and sprays. However when large populations of mosquitoes emerge from the breeding areas outside the district, residents of Greater Winnipeg do experience mosquito annoyance. \Vhenever this occurs prompt fogging operations are required to relieve this distress . It must r emain our objective, therefore, to develop means to intercept invading mosquitoes from breeding areas beyond reach of the larviciding program so that we may become less dependent on emergency measures such as fogging. On the basis of our preliminary experience last summer we are now in a position to investigate this prob1em intensively in 1960. The contributions elsewhere in this report by the student investigator Mil' R. Brust, B.S .A. , and Field Manager Mr P Belski, indicate the diversity and extent of our investigations. The support of the Greater Winnipeg Mosquito Abatement District and the Defence Research Board of Canada will enable us to consolidate our findings and extend our studies to mosquito control. R. A. BRUST B.S.A., Technical Assistant Breeding Survey (a) Aircraft Applications Pre-season applications of DDT gran ules were u sed to eliminate breeding of mosquito larvae on 10,856 acres of bushla nd in 1959 (1 lb. of actual DDT per. acre) A few sm all tracts were controlled with DDT sprays from trucks. A survey was conducted on all acres trea ted in the fall of 1957 and 1958 and mosquito breeding was found in only two localities. This survey shows that applications of 30 % DDT in vermiculite is an effective measure of breeding control. (b) Ground Spray Although DDT in an oil spray was applied from trucks on 7,699 acres of swamp land andi ditches, breeding was found in ditches on June 29. Presumably excessive rainfall early in the season caused much of the insecticide treatment to be carried down ditches to the rivers. Ground crews kept ditches and accessible low lyi ng areas well sprayed to arrest further larval development. Adult Mosquito Survey Mosquito light traps were operated from May 14 to September 3 (Fig. 1) outside a nd inside t he Greater Winnipeg District. Due to excessive rainfall in early spring (F'ig. 2) and above normal temperatures in early June, the peak of ad ult emergence was reached approximately one month earlier th an the two previous years. Comparatively high numbers of adults appeared in May · the largest occurred in June. On the basis of our records for 1957 and 1958 h eavy precipitation is followed by a peak of adult emergence after 10 14 days provided the temperature exceeds 60 ° F If the temperatures are lower the adult emergence occurs after 18 24 days. Ultra-Violet Light Traps One ultra-viole t florescent lamp was fitted to a new Jersey light trap. Daily catches were comparedi to standard incandescent light bulb traps (Fig. 3) at Oak Bluff and Kildonan Park. The ultra-violet and standard light bulb traps stood approximately 10 feet apart. In as much as ultra-violet light traps appear to be four times more effective they would have many uses where the trapping of large numbers is necessary for example, in the recovery of tagged insects.

Several thousand adult mosquitoes were taken to the Virus Laboratory of the Winnipeg General Hospital. Under the direction of Dr W L. Parker, the mosquitoes were assayed for viruses but none were found. 11 Year DDT History in Mosquito Control The World Health Organization Kit was used to test mosquito resistance to DDT. The Greater Winnipeg Mosquito Abatement District has usedl DDT for mosquito control for the 11th year and to date no resistance has been found. DDT concentration of .004 parts per million gave 100% control. DDT resistance is not suspected unless LC50 is greater than .1 parts per million for Aedes and Anopheles, or 1 p.p.m. for Culex species. (LC50 dosage required to kill 50'% of the mosquito sample) May Culiseta inornata Aedes dorsalis Aedes fitchie Aedes ftavescens Aedes ~richsonii Aedes eristalis Aedes compestris June July Aedes vexans Culiseta inornata Culex tarsalis Aedes dorsalis Aedes stimulans Aedes spencerii Aedes ftavescens Aedes communis Aedes diantaeus Aedes intrudens Aedes sollictans Aedes cinerus Aedes vexans Culiseta inornata Anopheles earlei Culex tarsalis Culex restuans Mansonia perturbons Aedes intrudens Aedes stimulans Auqust Aedes vexans Aedes dorsalis Culiseta inornats Culex restuans Mansonia perturbons Anopheles earlei Aedes riparius Culex apicalis Aedes spencerii Larval Control with Detergents DDT Barrier Experimental test results of one particular detergent are given in table 1. Four brand name detergents were used in the laboratory i.ests but no appreciable difference in larval mortality was observed. A barrier spray an vegetation was laid down north of Winnipeg. This so-called insecticide carpet was deposited on June 16, 1959, with ground equipment at the rate of 2 lbs. DDT in No. 2 Fuel Oil per acre, on a strip 100 feet wide and 5 miles long. Mosquito light traps were located on both sides of the barrier, but due to the early peak of mosquito emergence this past year, insufficient information was obtained as to predict the value of this type of protection. If the experimental barrier proves effective it could be expanded to protect the city from outside invasions of mosquitoes. TABLE 1.
