In the search for novel potent fungi-derived bioactive compounds for bioinsecticide applications, crude ethyl acetate culture filtrate extracts from 110 mangrove fungal endophytes were screened for their toxicity. Toxicity tests of all extracts against brine shrimp (Artemia salina) larvae were performed. The extracts with the highest toxicity were further examined for insecticidal activity agai...

We attempted to search novel Bacillus thuringiensis strains that produce crystals with potential utility in plant protection and with higher activity than strains already used in biopesticide production. Seven B. thuringiensis soil and water isolates were used in the research. We predicted the toxicity of their crystals by cry gene identification employing PCR method. The isolate MPU B63 with i...

The development of an effective and green bioinsecticide is a research hotspot. This study demonstrated the possibility using arsenic (As) hyperaccumulator as bioinsecticide. When As concentration in Pteris vittata fronds exceeded 138 mg kg?1, larva hawk moth (Theretra clotho) displayed apparent preference to lower-As-concentration P. fronds. body was high 850 kg?1. Such might have been case th...

Pest and disease attacks are one of the obstacles in increasing shallot production Palu Valley, Central Sulawesi. Farmers still rely on use synthetic pesticides to control pests diseases, which results a high demand for insecticides fungicides. This community service aims disseminate pest technology with bioinsecticide Beauveria bassiana biofungicide Trichoderma, as well train farmers develop a...

Grape berries attacked by Lobesia botrana larvae are more easily infected by Aspergillus section Nigri (black aspergilli) ochratoxigenic species. Two-year field trials were carried out in Apulia (Italy) to evaluate a bioinsecticide control strategy against L. botrana and the indirect effect on reducing ochratoxin A (OTA) contamination in vineyards. A commercial Bacillus thuringiensis formulate...

Despite the promising acute and chronic toxicity of commercial acetogenin-based bioinsecticide formulations reported for different arthropod pests and their recent registration, we are unaware of any published study that examines the compatibility of these botanical derivatives with entomopathogenic fungi, which are important natural and applied biological control agents. We investigated the co...
