The use of biopesticides against agricultural pests is great importance for the sustainability pest management. goal present study was to determine lethal (acute) and sublethal (first male young queen emerge time, competition point, total number workers, males queens) effects four commercial [Nibortem (1.5% Lecanicillium (Verticillium) lecanii strain V1-1, Nostalgist Beauveria bassiana Bb-1), P...

The nematophagous fungus Verticillium chlamydosporium secreted several proteases in submerged culture in which soya peptone was the sole carbon and nitrogen source. One protease, VCP1 (M(r) 33,000, pI 10.2), was purified 14-fold from culture filtrates to apparent homogeneity using preparative isoelectric focusing in free solution, and shown to rapidly hydrolyse the chymotrypsin substrate Suc-(A...

24 25 The argasid ticks O. erraticus and O. moubata are of great medical and veterinary 26 importance because they are vectors of the African swine fever virus and several species of 27 human relapsing fever borreliae. Biocontrol of these ticks using entomopathogenic fungi has not 28 been previously reported. We examined the pathogenicity to different developmental stages of 29 these two argasi...

Some herbivore-induced-plant volatiles (HIPVs) compounds are vital for the functioning of an ecosystem, by triggering multi-trophic interactions for natural enemies, plants and herbivores. However, the effect of these chemicals, which play a crucial role in regulating the multi-trophic interactions between plant-herbivore-entomopathogenic fungi, is still unknown. To fill this scientific gap, we...

Abstract Background Okra, Abelmoschus esculentus (Linn.) Moench, is one of the most important traditional vegetables in India. The crop attacked severely by sucking pests, viz., jassid, Amrasca biguttula Ishida, and whitefly, Bemisia tabaci Genn., throughout its growth period. To control these different entomopathogenic fungi (EPF), Beauveria bassiana , Metarhizium anisopliae Lecanicillium leca...
