Dose Response Relationship of Subterranean Termite, Heterotermes indicola (Wasmann) and Two Insect Growth Regulators, Hexaflumuron and Lufenuron

The subterranean termite Heterotermes indicola (Wasmann) is one of the most economically important and destructive pest species in Pakistan. It is hard to control with conventional termiticides because of its cryptic foraging behavior and biology. Laboratory studies were conducted at Nuclear Institute for Food and Agriculture (NIFA) Peshawar, Pakistan to test various concentrations ranging from 100 – 10,000 ppm (wt/wt) of hexaflumuron and lufenuron to determine dose response relationship. It was concluded that hexaflumuron caused <50% mortality in termites exposed to 100 – 5000 ppm whereas at 10,000 ppm it caused >70% mortality after 25 days and ELT90 projected was 74 days. In dose-response study of lufenuron all the concentrations equal or greater than 250 ppm caused > 50% mortality but maximum mortality recorded was >70% which was caused by 10,000 ppm and ELT90 recorded was 49.2 days. Both hexaflumuron and lufenuron exhibited characteristics of slow acting toxicants and cause delayed mortalities at all the tested concentrations. Although Lufenuron was found to be relatively more toxic than hexaflumuron but overall mortalities were dose dependent.
