background:  the residual effect of triflumuron and pyriproxyfen on musca domestica l larval stages was studied in the laboratory. methods : both igrs at varying concentrations ranging between 0.5 to 2.5 mg/l were placed inside beakers with mice chow and vitamin b complex and water as food for the 1 st , 2 nd and 3 rd instars m.domestica larvae. results: both igrs inhibit m. domestica adult eme...

no doubt, damage and losses inflicted by callosobruchus maculatus to stored products in general and chickpea in particular can be significant. the objective of this work was to evaluate the effect of the verbascum sinuatum powder on c. maculatus oviposition behavior in chickpea under laboratory conditions (30 °c, 60% relative humidity). powder of mullein plant (v. sinuatum) caused reduction in ...

Five pools containing immature stages of Anopheles punctulatus were treated with pyriproxyfen at 4 different dosages. Inhibition of adult emergence was observed in pupae collected from the test pools and/or those obtained by rearing of the 4th instar larvae. Adult emergence was inhibited completely for 2 months at a dosage of 0.1 ppm, for one month at 0.05 ppm and 0.01 ppm, and for 20 days at 0...

Malaria and filariases are prevalent in Sudan and their control depends largely on preventive measures against mosquito vectors. The present work aimed to investigate the larvicidal, adults emergence inhibition and oviposition deterrent effects of aqueous extracts from leaves of Ricinus communis L. against the mosquitoes, Anopheles arabiensis and Culex quinquefasciatus as a biological control m...

The granular formulation of 0.5% pyriproxyfen was evaluated for inhibition of emergence of Aedes togoi in brackish water of rock pools near a coastal area in Pusan, South Korea. Complete adult emergence inhibition in 4th-stage larval and pupal isolations was affected from 5-40 days at 0.05 mg/l after treatment. Most inhibition rates were over 80% throughout the test period at all test concentra...
