Abstract
Background & objectives: Houseflies are one of the major pest problems worldwide. The current housefly control strategy in the country hinges on the use of Dichlorvos as a housefly larvicide and
pyrethrum spray in kitchens/dining areas. The present study was undertaken to evaluate the newer
housefly control options in the wake of concerns about human toxicity of Dichlorvos and its
continued use in public health.
Methods: Efficacy of Diflubenzuron WP and granule formulations (chitin synthesis inhibitor) visà-
vis Dichlorvos EC in the control of housefly was assessed in laboratory by adult emergence
inhibition after treatment and in field conditions by estimation of density post-application up to
three weeks using standard methods.
Results: Dichlorvos EC and Diflubenzuron formulations (WP and granule) brought about 100%
inhibition of adult emergence under laboratory conditions. However, in the field evaluation, effective
suppression of housefly population was brought about by Dichlorvos and Diflubenzuron granule
formulation (though delayed).
Conclusion: Dichlorvos EC and Diflubenzuron granule formulation are effective housefly larvicides.
It is recommended that Diflubenzuron WP formulation be evaluated at a higher frequency to
enhance its effectiveness and its use may be considered in conjunction with an initial suppression of housefly adults with an adulticide, e.g. Cyphenothrin, etc.
