Dispersion And Physiological Ecology Of Mosquito Adults In Louisiana Ricelands., Alan Richard Holck
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 …
Neogene Basin Evolution In The Southwestern Dominican Republic: A Foraminiferal Study., Peter Paul Mclaughlin Jr
Neogene Basin Evolution In The Southwestern Dominican Republic: A Foraminiferal Study., Peter Paul Mclaughlin Jr
LSU Historical Dissertations and Theses
The Azua Basin sequence is a 2500 m thick Miocene Pliocene regressive interval. Limestones and marls of the Sombrerito Formation, the lowermost unit, ranges from lower Miocene to lowermost upper Miocene. The turbidite sequence of the Trinchera Formation spans an interval from uppermost middle Miocene to lower Pliocene. Blue-green, neritic lower Pliocene siltstones of the Quita Coraza Formation overlie the Trinchera in the seaward part of the basin. Shallow-marine strata in the lower part of the Arroyo Blanco Formation range from uppermost Miocene to middle Pliocene. Principal Components Analysis of rich benthic foraminiferal faunas aided in the recognition of species …
Ecological Studies Of Velvetbean Caterpillar, Anticarsia Gemmatalis Hubner, Pupae In Louisiana Soybean Fields., Joon-Ho Lee
Ecological Studies Of Velvetbean Caterpillar, Anticarsia Gemmatalis Hubner, Pupae In Louisiana Soybean Fields., Joon-Ho Lee
LSU Historical Dissertations and Theses
The microhabitat distribution of velvetbean caterpillar (VBC), Anticarsia gemmatalis Hubner (Lepidoptera: Noctuidae) was studied in soybean field cages and fields during 1985, 1986 and 1987. Larval density did not affect pupal horizontal distribution patterns related to direction and distance from the plant row. Pupae were found equally on both sides of soybean plant rows in a cage study. Pupae were found on and below the soil surface, but not on the plant. In 51 cm row spacing, both equal number and similar dispersion pattern of pupae were found on either side of the plant row. In 91 cm row spacing, …
