Field Control of Nuisance Chironomidae (Diptera) by Bacillus thuringiensis serovar. israelensis and s-Methoprene: A Simultaneous Comparison

Metadata Updated: December 11, 2019

Non-biting midges of the family Chironomidae (Diptera) are one of the most ubiquitous, diverse, and ecologically important groups of aquatic invertebrates. Chironomids are the most widespread insects in freshwater, and occur on all continents including Antarctica. The larvae occupy a broad spectrum of aquatic and semi-aquatic habitats including brackish and marine waters, and even inhabit some semiterrestrial and terrestrial biotopes. Among the chironomid control methods adopted in various midge problem situations world-wide, chemical control has been the most widely and successfully used. However, because of environmental sensitivity and the possibility of midge larvae being a source of food for the endangered stilts as well as breeding coots and their young in Kealia Pond, a thorough investigation of the effects of the possible control materials on target larval Chironomidae and associated nontarget invertebrates in the pond was deemed necessary. Two control materials, the commercially produced bacterium, Bacillus thuringiensis serovar. israelensis (Bti) mixed in a sand grain formulation, and a commercial pellet formulation (STRIKE pellets) of the juvenile hormone analog insect growth regulator (IGR), s-methoprene were selected for evaluation in the pond. The overall objectives of this research were to study the efficacy of Bti and s-methoprene against populations of P. nubifer and their non-target impacts, and to examine whether drift of either of these materials, as a result of wind and undercurrents, occurred beyond designated treatment areas.
