Insect-specific ascoviruses with a circular genome are distributed in the USA, France, Australia and Indonesia. Here, we report the first ascovirus isolation from Spodoptera exigua in Hunan, China. DNA-DNA hybridization to published ascoviruses demonstrated that the new China ascovirus isolate is a variant of Heliothis virescens ascovirus 3a (HvAV-3a), thus named HvAV-3h. We investigated the ph...

The tobacco caterpillar, Spodoptera litura F., is one of the most devastating, cosmopolitan polyphagous pests affecting major crops that significantly impact agricultural productivity. present study aimed to evaluate toxicological effect seed extract medicinal plant, Annona squamosa L. and histological on midgut under laboratory conditions. crude methanolic A. was tested against third instar la...

One of the biological controls pest and plant disease is use enophytic bacteria. This study aimed to obtain endophytic bacterial from root tissue shallot plant, which potential as entomopathogens against larvae Spodoptera litura. research was arranged in a completely randomized design (CRD) with nine treatments consisting eight bacteria (isolation tissue) one control three replications.
