Dispersion And Physiological Ecology Of Mosquito Adults In Louisiana Ricelands., Alan Richard Holck
LSU Historical Dissertations and Theses
A sampling technique for estimating the size of adult mosquito populations in vegetation was developed. Regression analysis was used to obtain absolute density estimates from sweep net. Diurnal population size estimates of Louisiana riceland mosquitoes were made on a 35.6-square km site 5 km south of Kaplan, LA. Four mosquito species were present: Psorophora columbiae, Anopheles quadrimaculatus, An. crucians and Culex salinarius. Mosquito species were highly stratified in their distribution. Psorophora columbiae was primarily observed in pastures with livestock and in rice fields. Both Anophelines were found only in structures. Culex salinarius did not exhibit habitat preference. Anopheles quadrimaculatus exhibited …

Feeding punctures of the rice stink bug (RSB), Oebalus pugnax (F.), provide fungi entry sites into rice, Oryza sativa (L.), grains and kernels (hulled grains). Feeding sheaths also serve as a source of nutrients for fungi. Grain spotting fungi did not affect the percentage of spotted kernels (pecky rice) and significantly reduced full grain weight only at low infestation rates of one and two RSB per panicle. Panicles had been treated with a single application of propriconazol (1000 ppm) soon after flowering and later infested in the early milk stage with RSB adult pairs for 9 days. Propriconazol was not …
