This paper deals with the semiotic meanings which are given both to the appearance and/or behavior of insect species according to the ethnoentomological knowledge of the inhabitants of the village of Pedra Branca, Bahia State, Brazil. Data were collected from February to May 2001 by performing open-ended, recorded interviews with nine men and twenty-five women, whose ages ranged from 19 to 82 y...

In moths, which include many agricultural pest species, males are attracted by female-emitted sex pheromones. Although integrated pest management strategies are increasingly developed, most insect pest treatments rely on widespread use of neurotoxic chemicals, including neonicotinoid insecticides. Residual accumulation of low concentrations of these insecticides in the environment is known to b...

RNA interference (RNAi) is an important mechanism that protects cells of eukaryotic organisms from foreign genetic information and regulates physiological processes. Discovery RNAi development the methods for targeted suppression expression individual genes have opened up wide opportunities elucidating gene functions solving many problems in biology, medicine, plant protection. This approach ca...

Insects are the main pest in agricultural systems, causing significant losses crop productivity and storage. During last decades control of insects has been carried out through uncontrolled massive use chemical insecticides, very harmful to environment health, which requires development new efficient safe alternatives. Numerous fungal species have described as entomopathogens insect pests, well...

Three Sitophilus species (S. granarius L., S. oryzae L., and S. zeamais Mots.) are closely related based on DNA analysis of their endosymbionts. All are seed parasites of cereal crops and important economic pest species in stored grain. The Sitophilus species that currently exist, including these three species, are generally believed to be endemic to Asia's forested areas, suggesting that the f...
