In a laboratory study, the insect growth regulator, cyromazine, exerted a high level of biological activity on Aedes aegypti and Culex quinquefasciatus treated in the 4th larval instar. At 1.5 and 1.0 ppm this IGR produced 97 and 99% inhibition of emergence in adult Ae. aegypti, respectively. In Cx. quinquefasciatus, there was 99% inhibition at 1 ppm and complete inhibition at 1.5 ppm. The over...
Social insects frequently engage in oral fluid exchange - trophallaxis - between adults, and between adults and larvae. Although trophallaxis is widely considered a food-sharing mechanism, we hypothesized that endogenous components of this fluid might underlie a novel means of chemical communication between colony members. Through protein and small-molecule mass spectrometry and RNA sequencing,...
the mediterranean flour moth, ephestia kuehniella zeller, is one of the major pests in stored products worldwide. several problems assossiated with the use of conventional insecticides have strongly demonstrated the need for applying alternative safe compounds such as insect growth regulators (igrs). in the present study, growth regulating activity and hematological effects of pyriproxifen and ...

Abstract Plant growth regulators are chemical substances which govern all the factors of development and within plants. The application plant to crops modifies hormonal balance leading increased yield, enhanced crop tolerance against abiotic stress improved physiological trait crops. Paclobutrazol (PBZ) [(2RS, 3RS)-1-(4-chlorophenyl)- 4, 4-dimethyl-2-(1H-1, 2, 4-trizol-1-yl)-pentan-3-ol], is on...
ABSTRACT Some vegetables have been used as an innovation in the ornamental plant market, such cauliflower, which has well-defined morphological traits. This study aimed to evaluate effect of paclobutrazol, applied via soil, order produce cauliflower for purposes. The design was completely randomized with five treatments and seven replicates. consisted doses growth regulator paclobutrazol (PBZ) ...
Drought Stress is one of the most important limiting factors in plants growth and development. Growth regulator, Trinexapac-ethyl, might improve drought stress resistance via reducing stem growth and improving osmotic adjustments. In present study Trinexapac-ethyl effect on some tall fescue var Rebel physiological and morphological traits under irrigation free conditions was studied. So, an exp...
