J. Econ.Entomol.79: 1139-1142 (1986) ABSTRACT A Heliothis cone trap captured significantly higher numbers of male European corn borers, Ostrinia nubilalis (Hubner), than a sticky wing trap. Behavioral observations revealed that the difference in number of males captured was related to the proportion of moths approaching the traps that was subsequently captured. Cone traps baited with a 97:3 ble...

Ann. Entomol. Soc. Am. 81(6): 977-985 (1988) ABSTRACT The organization of the tympanic nerve within the thoracic ganglia of Heliothis zea (Boddie) was investigated. Cobalt chloride infiltration of cut axons was used to investigate the central terminations of the tympanic nerves. The axonal terminals of the A2 acoustic cell were confined to the meso-metathoracic ganglia, whereas the Al acoustic ...

The controversial question of the possible autonomy of centrioles, as shown by the persistence of all or part of them in the generative cell line throughout the life cycle of organisms, remains unresolved. All previous reports on shedding or withdrawal of cilia and flagella showed that their basal bodies (= centrioles) were retained in the cells where they may, or may not, subsequently disassem...

The development of pest resistance to transgenic crop plants producing insecticidal toxins from Bacillus thuringiensis Berliner (Bt) poses a major threat to their sustainable use in agriculture. "Pyramiding" two toxins with different modes of actions in the same plant is now being used to delay the evolution of resistance in the insects, but this strategy could fail if a single gene in a pest c...

From 2004 through 2005, plots of experimental transgenic cotton lines containing the vegetative insecticidal protein, Vip3A; δ endotoxin, Cry1Ab; and both Vip3A and Cry1Ab were evaluated for efficacy against certain lepidopteran pests. Results showed that the cotton line containing Vip3A was more efficacious against the beet Spodoptera exigua (Hübner) and fall armyworm Spodoptera frugiperda (J....

Analogues of the small protein Manduca sexta eclosion hormone (62 amino acids) were synthesized by Fmoc solid-phase methodology. Matrix-assisted laser desorption ionization mass spectrometry (MALDI-MS) was used to analyze the products of the syntheses and this information was used to design an efficient purification scheme. MALDI-MS was used to monitor the target products through purification a...
