The application of larvicide from botanical origin was extensively studied as an essential part mosquito prevention. This study aimed to assess the difference in container index (CI) based on characteristics water containers using <em>Ziziphus mauritiana</em> leaf extract solution. A quasi- experiment research done among 300 selected with temephos a control and 9% solution treatment...

The fate and persistence of the mosquitocidal bacterium, Bacillus sphaericus, in dairy wastewater lagoons was evaluated in conjunction with trials of its larvicidal efficacy against Culex stigmatosoma. Two commercial formulations, BSP-2 (at 4.48 kg/ha) and ABG-6184 (at 2.24 kg/ha) gave about 90% reduction for up to 4 weeks, although surface water lost its insecticidal activity by 3 days posttre...

We have evaluated Photorhabdus insect-related protein (Pir) from Photorhabdus asymbiotica against dengue vectors. PirAB shows larvicidal activity against both Aedes aegypti and Aedes albopictus larvae but did not affect the Mesocyclops thermocyclopoides predator. PirAB expressed the strongest toxicity compared to PirA, PirB, or the mixture of PirA plus PirB. Whether the presence of an enterobac...

We report the engineering of the surface of the tobacco mosaic virus (TMV) virion with a mosquito decapeptide hormone, trypsin-modulating oostatic factor (TMOF). The TMV coat protein (CP) was fused to TMOF at the C terminus by using a read-through, leaky stop codon that facilitated expression of CP and chimeric CP-TMOF (20:1 ratio) that were coassembled into virus particles in infected Nicotian...

Efficacy of Bacillus sphaericus strain GC subgroup IV (Bs) isolated from Assam, India as water dispersible powder formulation has been evaluated in laboratory and field conditions. Laboratory evaluation revealed that Bs, Spherix, ABG 6262 and Bti 164 (serotype H14) produced 90% mortality in Cx. quinquefasciatus @ 0.5, 0.6, 0.75, and 0.7 ppm respectively. In field trial Bs dosage @ 0.1 g/m2 in f...

while the «classical insecticides» (ddt: dieldrin, malathion, etc.) mainly affect the adult stage of insects, dimilin belongs to a new group of insecticidal compounds that kills the insect in its larval stages, but has no lethal affect on the adult insect. its empirical formula is c14h9h2~f2cl. diflubenzuron is proposed as common name for the trade name dimilin. studies were made on c. pipiens,...
