The aim of this study was to determine the effects phenolic substances in different plants (mulberry, apple, walnut and plum) on hemocyte counts antioxidant enzyme activities Hyphantria cunea larvae infected with granulovirus (HycuGV) uninfected. In study, contents plant materials were firstly determined. Then, these ingredients uninfected As a result all groups increased infection activity, ph...

The larvae of the fall webworm, Hyphantria cunea (Dru.), though vulnerable to cyanide poisoning, consume the cyanogenic leaves of black cherry, Prunus serotina, without apparent harm. The cyanide contents of leaves, defensive regurgitant, the bolus, and frass were assayed by ion chromatography to determine the fate of the toxin in the caterpillar. Leaves collected in September, when the caterpi...

Host range factor 1 (HRF-1) of Lymantria dispar multinucleocapsid nucleopolyhedrovirus promotes Autographa californica MNPV replication in nonpermissive Ld652Y cells derived from L. dispar. Here we demonstrate that restricted Hyphantria cunea NPV replication in Ld652Y cells was not due to apoptosis but was likely due to global protein synthesis arrest that could be restored by HRF-1. Our data a...
