The present study has been conducted to investigate the effect of insect growth regulator BAY SIR 8514 on chitin and chitinase enzymes of 2 in star of Spodoptera littoralis larvae, the effect of sublethal doses, LC 25, LC 50 and LC90 shows a significant effect on antifeedant index, on the other hand larval treatment with the tested IGR doses revealed, certain histo-pathological symptoms such as...

Plasma membrane H+-ATPase is a major integral membrane protein with a role in various physiological processes including abiotic stress response. To study the effect of NaCl on the expression pattern of a gene encoding the plasma membrane H+-ATPase, an experiment was carried out in a completely random design with three replications. A pair of specific primers was designed based on the sequence o...

the use of adjuvants enhances the insecticide efficiency and increases the persistence of insecticides. in this study, the effect of adjuvants on the toxicity of chlorpyrifos and cyhalothrin formulations were investigated under laboratory and field conditions. the comparative toxicity of two chlorpyrifos [(48% emulsifiable concentrate (ec)] formulations (dursban and pyrifos el nasr), two cyhalo...

aloe littoralis baker (asphodelaceae family) is a well known plant in southern parts of iran. because of its use in iranian traditional medicine as a wound-healing agent, the present study was carried out to investigate anti-inflammatory and wound healing activities of this plant in wistar rats. a. littoralis raw mucilaginous gel (alrmg) and also two gel formulations prepared from the raw mucil...

The present study was conducted to find the effect of three heavy metals, Ag, Hg and Pb on the expression level of a gene encoding plasma membrane H+-ATPase in Aeluropus littoralis. The experiment was laid out in a completely random design with three replications. The expression of the main gene was normalized to the expression of the housekeeping gene actin. Two 259 and 187 bp fragments were a...

Flea beetles of alligator weed, Alternanthera philoxeroides (Martius) Grisebach (Amaranthaceae), were collected in Argentina, Uruguay, Paraguay, and Brazil. Species in the genera Disonycha Chevrolat, Agasicles Jacoby, Systena Chevrolat and Phenrica Bechyné were frequently found on this weed. Phenrica littoralis (Bechyné) was the most abundant within this genus. The male is described and the hol...
