Abstract:
... The entomopathogenic fungus Metarhizium majus (isolate no. CPCRIMKY-1) is a potential bio control agent against the major pest of banana, Odoiporus longicollis (Olivier). Banana is highly vulnerable to a plethora of pests and diseases which are managed by the application of pesticides. Hence, it is imperative that the reactions of these pesticides when used in banana agro-system with M. majus, is ...

Recent global water surveys have found neonicotinoid insecticides in waterbodies adjacent to agricultural fields. The presence of neonicotinoids in surface waters raises the concern of the potential risk of exposure to non-target aquatic species, with relevance for both free-living and parasitic t ...

Urinary concentrations, however, can vary greatly over time due to variable exposure, potentially leading to exposure misclassification. In this study, within- and between-individual variability of urinary concentrations of 13 neonics a ...
