Seventeen chemicals, mostly organic and inorganic acids, were tested in combination with gypsy moth nucleopolyhedrosis virus (NPV) for enhanced pathogenicity in Lymantria dispar (L.) larvae. Two acids (sorbic and boric) appeared to enhance viral activity, as expressed by increased mortality in treated larvae. The effects of boric acid were investigated more thoroughly, and in each test boric acid significantly enhanced viral activity (LC50 of NPV-H2) standard = 5.0 × 103 polyhedral inclusion… Expand
Formulation of a nucleopolyhedrovirus with boric acid for control of Spodoptera frugiperda (Lepidoptera: Noctuidae) in maize
The degree of potentiation of boric acid toward SfM- NPV in a granular phagostimulant formulation was determined and offered an economical means of enhancing bac- ulovirus activity with little apparent risk to nontarget arthropods. Expand
Efficacy of nucleopolyhedrovirus and azadirachtin on Spodoptera litura Fabricius (Lepidoptera: Noctuidae)
Food consumption, efficiency of conversion of ingested and digested food, relative growth rate, and consumption index values declined significantly, but at the same time an increase in approximate digestibility was also observed. Expand
Biological and Immune Response of Galleria mellonella (Lepidoptera: Pyralidae) to Sodium Tetraborate
It is inferred that sublethal levels of dietary ST substantially influence life history parameters and immunocompetence in G. mellonella. Expand
The effects of azadirachtin and nucleopolyhedrovirus on midgut enzymatic profile of Spodoptera litura Fab. (Lepidoptera: Noctuidae)
A synergistic effect of botanical insecticides and virus was found when combined in low doses and these effects are most pronounced in early instars. Expand
Potentiating Effects of Neem on Nucleopolyhedrovirus Treatment of Spodoptera litura Fab.
The effects of neem seed kernel extract (NSKE), neem oil (NO) and nucleopolyhedrovirus (NPV) of the Spodoptera litura Fabricius (Lepidoptera: Noctuidae) on the mortality, feeding and development ofExpand
Effects of a nucleopolyhedrovirus in mixtures with azadirachtin on Spodoptera frugiperda (J. E. Smith) (Lepidoptera: Noctuidae) larvae and viral occlusion body production
It is concluded that AZA + SfMNPV mixtures are unlikely to be useful for the mass production of this virus and laboratory observations on the value of AZA+ Sf mixtures as a potentiator of biological insecticides require validation in field studies under commercial growing conditions. Expand
Combined effects of azadirachtin and nucleopolyhedrovirus (SpltNPV) on Spodoptera litura Fabricius (Lepidoptera: Noctuidae) larvae
It is suggested that treatments with AZA and SpltNPV at appropriate combinations of concentration levels may result in improved control of tobacco cutworm compared with treatment with either AZA or virus alone. Expand
Two Year Field Study to Evaluate the Efficacy of Mamestra brassicae Nucleopolyhedrovirus Combined with Proteins Derived from Xestia c-nigrum Granulovirus
Alkaline soluble proteins of capsules (GVPs) of Xestia c-nigrum granulovirus can increase infectivity of some viruses including Mamestra brassicae nucleopolyhedrovirus (MabrNPV), and results indicate that GVPs are promising additives for virus insecticides. Expand
Synergism between Metarhizium anisopliae (Deuteromycota: Hyphomycetes) and Boric Acid against the German Cockroach (Dictyoptera: Blattellidae)
Abstract Mortality of German cockroaches, Blattella germanica (L.), caused by Metarhizium anisopliae (Metschnikoff) Sorokin strain AC-1 alone and in combination with different formulations of boricExpand
Controle microbiano da traça-da-batata, Phthorimaea operculella (Zeller, 1873) (Lepidoptera:Gelechiidae), com granulovírus
PhopGV can be produced in vivo on potato tubers at 24-30 °C, and the use of this virus in combination with talc or DalNeem, both at lower concentrations, was very efficient against PTM and must be considered in integrated management programs. Expand
