Use of fecal extract trails to enhance trap catch in German cockroach (Dictyoptera: Blattellidae) monitoring stations
Autor: J. L. Nation, P. G. Koehler, Dini M. Miller
Publikováno v: Journal of economic entomology. 93(3)
An aqueous extract of German cockroach, Blattella germanica (L.), fecal material was evaluated for inducing trail-following behavior in German cockroaches. In arena tests the fecal extract was found to stimulate trail following in 74% of adult male c

Vitellin and vitellogenin in the soldier bug, Podisus maculiventris: identification with monoclonal antibodies and reproductive response to diet
Autor: J P, Shapiro, H A, Wasserman, P D, Greany, J L, Nation
Publikováno v: Archives of insect biochemistry and physiology. 44(3)
A 171,000 M(r )polypeptide of Podisus maculiventris (Say) (Heteroptera: Pentatomidae) that constituted 16% of the protein in eggs also constituted up to 25% of the protein in hemolymph of fed females. It was identified as the major or sole apoprotein

Influence Upon Honeybees of Chronic Exposure to Very Low Levels of Selected Insecticides in Their Diet
Autor: S. J. Yu, Alan B. Bolten, J. L. Nation, F. A. Robinson
Publikováno v: Journal of Apicultural Research. 25:170-177
SummarySeveral sizes of hive were treated for colony viability and ease of manipulation when colonies of honeybees were confined within screened cages. Hives containing either a single standard frame (1742 cm2) or a single miniature frame (431 cm2) w

CONTROL OF A SEX-LIMITED HAEMOLYMPH PROTEIN BY CORPORA ALLATA DURING OVARIAN DEVELOPMENT IN PERIPLANETA AMERICANA (L.)
Autor: K. K. Thomas, J. L. Nation
Publikováno v: The Biological Bulletin. 130:254-264
1. The removal of corpora allata from females of the roach, Periplaneta americana, soon after the imaginal molt prevented growth and yolk formation in the oocytes.2. No immediate effect on ovarian development was noticed when mature adult females wer

RNA, PROTEIN AND URIC ACID CONTENT OF BODY TISSUES OF PERIPLANETA AMERICANA (L.) AS INFLUENCED BY CORPORA ALLATA DURING OVARIAN DEVELOPMENT
Autor: K. K. Thomas, J. L. Nation
Publikováno v: The Biological Bulletin. 130:442-449
1. The concentrations of RNA, proteins, and uric acid in the body tissues of allatectomized and sham-operated female roaches were measured at intervals after the imaginal molt. The concentrations of RNA and proteins were substantially lower in allate

Substances that Attract Caged Honeybee Colonies to Consume Pollen Supplements and Substitutes
Autor: F. A. Robinson, J. L. Nation
Publikováno v: Journal of Apicultural Research. 7:83-88
SummaryAddition to the diet fed to honeybee colonies in cages of either whole-pollen lipids, or the fraction soluble in cold acetone, resulted in a significant increase in the amount of food consumed. On the other hand addition of the fraction insolu

Concentration of Some Major and Trace Elements in Honeybees, Royal Jelly and Pollens, Determined By Atomic Absorption Spectrophotometry
Autor: J. L. Nation, F. A. Robinson
Publikováno v: Journal of Apicultural Research. 10:35-43
SummaryAtomic absorption techniques were used to determine K, Na, Ca, Mg, Cu, Fe, Mn and Zn in samples of pollens from corn (Zea mays), Citrus, longleaf and loblolly pines (Pinus taeda, P. palustris) and of mixed bee-collected pollens. On the basis o

Long-Chain Fatty Acids in Honeybees in Relation to Sex, Caste, and Food During Development
Autor: J. L. Nation, F. A. Robinson
Publikováno v: Journal of Apicultural Research. 9:121-127
SummaryThe fatty acid composition of the lipids in the honeybee were determined by gas-liquid chromatography. Larvae, pupae and newly emerged adults of the worker, drone and queen were studied, and determinations were also made on excreta, royal jell
