Abstract In the present study, we reconstruct phylogenetic relationships within chromosomally variable Sorex araneus species group based on 20 nuclear loci and mitochondrial cyt b gene. tree, Nearctic S. arcticus represents earliest offshoot of followed by Holarctic tundrensis Siberian daphaenodon . Five other distributed mostly in Europe form a well‐supported clade. Coding regions showed stron...

Sitophilus zeamais is one of the main pests stored corn. The objective present work was to identify resistance corn genotypes attack different densities S. zeamais. 15, 20, 25, 30 and 35 adult insects were used for infestation in samples four maize genotypes: Nutricional Embrapa, Milho Roxo, 8 Carreiras Palha Roxa. number emerged insects, grain mass loss, insect weight, longevity sex ratio eval...

J. Econ. Entomol. ii: 1144-1148 (1984) ABSTRACT Seed oils of many sapindaceous plants contain substantial amounts of cyanolipids. Several of these oils stimulated aggregation of the sawtoothed grain beetle, Oryzaephilus surinamensis (L.), and the confused flour beetle, Tribolium confusum (Jacquelin duVal). In a pitfall bioassay, they attracted the sawtoothed grain beetle and the rice weevil, Si...

Certain strains of the fungi Aspergillus flc~rus and A. parasitic-us produce a group of mycotoxic metabolites commonly known as the aflatoxins (Diener and Davis, 1969). The aflatoxins have been studied extensively since they were found first in peanuts, stored grains, and other agricultural products (Golumbic and Kulick, 1969). Aflatoxin B, (AFB,) is a known hepatocarcinogen and hepatotoxic age...
