In the cotton crop (Gossypium hirsutum L.), there is a complexity of pests that appear systematically, thus significantly reducing yield; and their population fluctuation strongly influenced by meteorological conditions result in greater or lesser density these insects. Thus, this work aimed to evaluate insect with sucking feeding behavior an area without irrigation plant under second-harvest c...

Sucking pests of cotton (Gossypium hirsutum L), such as thrips, or Thrips tabaci Lindeman, and jassid, Amrasca biguttula Ishida, are among the most threatening insect to young plants in Pakistan. New chemical insecticides have been trialed control their damage commercial fields. Formulations that show good suppression these pest’s populations, while sparing bio-controlling agents, always prefer...

Acylsugars are secondary metabolites exuded from type IV glandular trichomes that provide broad-spectrum insect suppression for Solanum pennellii Correll, a wild relative of cultivated tomato. Acylsugars produced by different S. pennellii accessions vary by sugar moieties (glucose or sucrose) and fatty acid side chains (lengths and branching patterns). Our objective was to determine which acyls...

the predatory bug orius niger wolff is an important predator of the onion thrips, thrips tabaci lindeman in the potato fields of ardabil region. in this study, preference for prey, predatory rate, body size, and some life history parameters of o. niger were studied on seven potato genotypes (including savalan, agria, morene, kondor, diamant, pi397082-2, and pi397097-2)infested to t. tabaciunder...
