Abstract
Data from field collections of third- and fourth-stage larvae of Culex tarsalis Coquillett and pupae were used to calculate expected frequencies based on the negative binomial distribution. The data fit the negative binomial with a dispersion constant (kc) of 0.0525. The decision limits for a sequential sampling plan were then calculated. Aerial applications of Bacillus thuringiensis Berliner serotype H-14 toxin controlled C. tarsalis larvae without producing any detrimental effects to predators. The best control was obtained on a field treated with B. thuringiensis H-14 toxin and stocked with mosquito fish.This publication has 2 references indexed in Scilit:
