Feeding and searching behavior of Chrysopa carnea Stephens
(1970)
Studies were conducted to determine the effect of various biotic and physical factors on the feeding and searching behavior of the larvae of Chrysopa carnea Stephens. The ultimate objective of these studies was to determine ...
Certain aspects of pheromone release and aggregation behavior in the southern pine beetle (coleoptera: scolytidae)
(1970)
The attractive principle responsible for aggregation of populations of the southern pine beetle, Dendroctonus frontalis Zimmermann, consists of two insect-produced compounds, frontalin and trans-verbenol, and volatiles ...
Influence of certain seasonal changes on the life history and diapause of the boll weevil, Anthonomus Grandis Boheman
(1970)
Progeny of boll weevils, Anthonomus qrandis Boheman, originally collected from the High Plains of Texas, were reared in precisely controlled bioclimatic chambers both in constant temperatures and in programs which simulated ...
Slow release formulations of aldicarb for soil applications
(1970)
Available data on the fate of aldicarb in soil were used to prepare a theoretical model illustrating the possible levels of aldicarb in soil following several rates and methods of application. Using this model as a basis, ...
Fate of 2, 3-dihydro-2, 2-dimethyl-7-benzofuranyl-N-methylcarbamate (Furadan) and 2-methyl-2-(methylthio) propionaldehyde-0-(methylcarbamoyl)oxime (Temik) in laying hens
(1970)
A single oral dose of Furadan-ring-C¹⁴ to hens at a rate of 2.7 mg/kg resulted in detectable residues in the eggs for 10 days after treatment. Maximum concentrations of Furadan equivalents occurred 4 days after treatment ...
Population suppression of the boll weevil, Anthonomus grandis Boheman, in the high and rolling plains of Texas
(1970)
A total population suppression program was directed against the boll weevil, Anthonomus grandis Boheman, in an 8-county area of the High and Rolling Plains of Texas during 1964-66. During the fall of 1964, technical malathion ...
The biology and control of the pecan weevil, Curculio caryae (Horn) in Texas
(1970)
The biology and control of the pecan weevil, Curculio caryae (Horn), was studied at Junction, Menard, and College Station, Texas, 1965-69. Data from field and laboratory studies were used to compute life tables for the ...
Comparative biological, behavioral and biochemical investigations of the cotton bollworm Heliothis zea (Boddie) and the tobacco budworm Heliothis virescens (F.)
(1970)
Similarities and differences in the biology, behavior and hemolymph proteins of the two closely related species, the bollworm, Heliothis zea (Boddie) and the tobacco budworm, Heliothis virescens (F.) were investigated. ...
