Spodoptera exigua Hübner (Lepidoptera: Noctuidae) is considered a polyphagous pest distributed worldwide with wide range of hosts, and also serious plague for vegetables ornamentals. The objective this study was to explore the occurrence entomopathogenic fungi in agricultural soils from Mexico evaluate its virulence effect on life cycle S. exigua. Selected isolates (HEB1 γ01) were used perform ...

The Indianmeal moth, Plodia interpunctella Hübner (Lepidoptera: Pyralidae), is a major stored product pest that is found throughout the world. In this study, the effect of oral exposure to Bacillus thuringiensis (Berliner) subsp. kurstaki (Bacillales: Bacillaceae) and azadirachtin was evaluated in third instar P. interpunctella under laboratory conditions. The median lethal concentration (LC50)...

Apis mellifera is a pollinator insect model in pesticide risk assessment tests for bees. However, given the economic and ecological importance of stingless bees such as Melipona scutellaris Neotropical region, well lack studies on effect insecticides these bees, toxicity should be carried out to understand whether affect both species same manner. Thus, present study quantified differential sens...

The research was carried out to determine the effect of substitutional moringa stem bark extract (MB extract) with basil (BS on mortality, LC50 and LT50 Aedes aegypti larvae. design using completely randomized (CRD) consist 6 treatments including control (without MB BS extracts), 500 mg extract, 350 150 200 300 50 450 extract.

The aim of this study was to observe the effect various vegetable insecticide extracts on controlling armyworm (Spodoptera litura) soybean plants in laboratory. research conducted at Plant Protection Laboratory, Faculty Agriculture, University Medan Area, from November 2021 April 2022, using a Completely Randomized Design (CRD) Non Factorial, consisting 7 treatment levels, namely: N0 = no (cont...

Locusts and grasshoppers (acridids) are among the worst pests of crops and grasslands worldwide. Metarhizium acridum, a fungal pathogen that specifically infects acridids, has been developed as a control agent but its utility is limited by slow kill time and greater expense than chemical insecticides. We found that expression of four insect specific neurotoxins improved the efficacy of M. acrid...
