An ongoing survey of termites in Ohio was initiated during spring 2001. The pest-management industry contributed substantially to termite-collecting efforts, which were coordinated by the Entomology Department, Ohio State University. This survey effort, including materials and procedures, is detaile...

High palatability is an essential requirement for ant baits. They should not exhibit repellency and the ingredients need to be acceptable to the ant species. Since various ant species react differently to ingredients such as solvents, preservatives, or food in a bait, the determination of the palata...

Laboratory trials were done describing the primary and secondary kill ofBlattella germanica (L.) in response to MaxForce Gold, a new 0.03% AI fipronil-based cockroach bait. In bioassays measuring primary kill, MaxForce Gold at 0.1 g product/m2 caused ca. 90% mortality (14 DAT) of adult males and fem...

It is well documented that human food infested by mites may cause anaphylaxis. To establish the mite “allergy-risk threshold” in stored grain, we asked how many mites cause allergenic reaction? In literature we found that exposure to more than 100 mites/g-1 dust increases the risk of sensitisation, ...
