Insecticidal activity of essential oil extracted from Morinda lucida was tested on pulse beetle Callosobruchus maculatus, which is a pest that causes serious damage to several pulses. The insecticidal activity was compared with two pesticides, Phostoxin and Primo-ban-20. 120 mixed sex adult C. maculatus were introduced, along with 30 g of cowpeas. Four concentrations (0.40, 0.20, 0.10, and 0.05...

Double-stranded RNA (dsRNA) has been applied to control insect pests due to its induction of RNA interference (RNAi) of a specific target gene expression. However, developing dsRNA-based insecticidal agent has been a great challenge especially against lepidopteran insect pests due to variations in RNAi efficiency. The objective of this study was to screen genes of chymotrypsins (SeCHYs) essenti...

Several pyridinylthiazolylazetidinones 4a-d, pyridinylthiazolythiazolidinones 5a-d and pyridinylthiazolylformazans 6a-d have been prepared from pyridinylthiazolylarylidines 3a-d. These compounds have been evaluated for insecticidal, anti-fungal and anti-bacterial activities. Compound 2-[2'-(3"-chloro-2"-oxo-4"-ohydroxyphenyl-1"-azetidinyl)-1',3'-thiazol-4'-yl) aminopyridine 4c has been found to...
