Effect of temperature on toxicity of selected insecticides to forest beetle Anoplotrupes Stercorosus / Interakcja temperatury z wybranymi insektycydami chrząszcza leśnego Anoplotrupes stercorosus

In 2007 and 2008 research on the impact of temperature, ranging from 14 to 39°C on the survivability of an adult Anoplotrupes stercorosus intoxicated by insecticide preparations from the group of phosphoorganic insecticides (diazinon), carbamate (pirimicarb), quinazolines (fenazaquin), oxadiazine (indoxacarb), benzoyl urea insecticides (teflubenzuron), neonicotinoids (acetamiprid) and pyrethroids (beta-cyfluthrin) was carried out. The results obtained indicate that all preparations used in tests had a positive temperature coefficient.

The Crystal Structure of N-(5-Phenyl-1,3,4-oxadiazol-2-yl)-N′ -benzoyl Urea, a Novel Insect-growth Regulator

The crystal structure of N-(5-phenyl-1,3,4-oxadiazol-2-yl)- N′-benzoyl urea, C16H12N4O3, a novel insect-growth-regulator (IGR), has been established; the crystal structure belongs to the triclinic system with Z = 2, and the urea linkage is coplanar with intramolecular hydrogen bond formation, making the structure analogous to a four-ring compound.
