The housefly, Musca domestica L. has a worldwide distribution and is prevalent wherever insanitary conditions abound. The most important public health concern is the potential of houseflies to transmit a large number of pathogens including microorganisms for diseases viz. typhoid, cholera, bacillary dysentery, diarrhoea, tuberculosis, poliomyelitis, anthrax, yaws etc. and many parasitic worms 1-5. The control of Musca domestica is therefore important not only for human health but comfort as well.
Baits are one of the most commonly used measures for housefly control. They bring about effective reduction in housefly abundance and are popular choice in residential areas and eateries. Imidacloprid, a member of the Neonicotinoid group of insecticides …show more content…
Similar results have also been found in the present study. The efficacy of Imidacloprid bait in keeping the fly nuisance low (about 85% reduction) up to five weeks post treatment when adopted as a sole measure for housefly control is fairly good. Similar results on efficacy of the product have been reported by other workers as well10, 12. The study results, however, indicate a drop in performance of Imidacloprid bait after achieving an initial steady decline in housefly density up to four weeks of continuous treatment (Fig 4). This aspect of its performance needs to be viewed in the light of its limitation as it appears at this juncture, that the product when adopted as a sole housefly control strategy may not exhibit continued efficacy when the housefly breeding area is close to the treatment sites thereby providing a constant source of infiltration. It may be ideal under such circumstances to use a housefly larvicide along with Imidacloprid bait for effective control of houseflies. Another limitation the product may exhibit is the delayed efficacy in instances when the density of adult houseflies is very high.
The failure in bringing about a reduction in fly density in the Propoxur bait treated areas and the subsequent increase in housefly abundance could be attributed to its failure in attracting flies as well as its lower killing efficacy in comparison to Imidacloprid (as brought out in the study) coupled with the termination of supplementary control measures being carried out in the areas prior to treatment with
