Abstract Cellulose is a potential source of fermentable sugars and promising cost-effective for biofuel production. This study aimed to obtain cellulolytic fungi from the intestine Asiatic rhinoceros beetle ( Oryctes L.). The were isolated using Potato Dextrose Agar (PDA) media spread plate method. Qualitative quantitative screening tests carried out 1% CMC (w/v) as sole carbon source. Twelve i...

Colorado potato beetle, Leptinotarsa decemlineata (Say), feeding, development, and survival to adulthood were examined after continuously exposing large larvae to Bacillus thuringiensis subsp. tenebrionis-treated potato foliage from the field. In laboratory assays, the overall consumption and the length of period to become prepupae were determined for larvae, which began as 3rd and 4th instars,...

Changes in climatic and policy environments combined with uncertainty related to stochastic environmental fluctuations make design of invasive pest policy challenging. These external changes are often exacerbated by changes in the species characteristics. We discuss facing local change and uncertainty when deciding ex ante on a specific policy strategy. Our empirical case deals with an invasive...

Environ.Entomol.13: 1010-1014 (1984) ABSTRACT Field experiments were carried out to determine if a copper-based fungicide known to deter feeding by the Colorado potato beetle, Leptinotarsa decemlineata (Say), in the laboratory, could suppress the growth of L. decemlineata populations in the field when used regularly for plant disease protection on tomatoes, potatoes, and eggplants. Larval densi...

White grubs, including Polyphylla olivieri Castelnau, are among the most economically important pests of orchard trees and other crops such as potato and sugar beet. The larvae feed on the roots of the host plants and their adults feed on the leaves. Several types of organisms are parasitic or phoretic on this pest, including three species of mites from Iran. Two new species of mites, namely Hy...
