Composition, quantification, and periodicity of sex pheromone gland volatiles from individualHeliothis virescens females
Sex pheromone gland volatiles from individualHeliothis virescens (F.) females were collected and analyzed on an SP-2330 capillary gas-liquid chromatography column for identification andExpand
Temporal pattern of sex pheromone release by female Trichoplusia ni
The nightly mean release rate of the pheromone component Z-7-dodecenyl acetate for individual female Trichoplusia ni increased significantly with age, although the time spent releasing phersomone per night decreased significantly withAge. Expand
Bait-preference Tests for the Argentine Ant (Hymenoptera: Formicidae)
In choice feeding tests, Argentine ant, Iridomyrmex humilis (Mayr), workers preferred 25% honey water or sucrose water over granulated brown sugar or other solid foods with high protein content suchExpand
Effects of gaster extract trail concentration on the trail following behaviour of the Argentine ant, Iridomyrmex humilis (Mayr)
The average horizontal distance from the centre of the trail at which ants exhibited following behaviour increased with concentration to 3–4 mm beyond the applied trail boundaries, indicating both an ability to follow airborne chemicals, and possibly a non-tolerance of excessively high concentration.

Sex Pheromones of Lepidoptera: Disruption of Pheromone Communication in Trichoplusia ni and Pectinophora gossypiella by Permeation of the Air with Nonpheromone Chemicals
Quantitative field experiments were conducted to evaluate looplure, hexalure, and 9 related compounds, as agents for the disruption of sex pheromone communication in T. ni and P. gossypiella, finding that the related compounds appear to have little potential for behavioral control of these 2 species.

Sex pheromones of noctuid moths: factors influencing antennal responsiveness in males of Trichoplusia ni.
Experimental evidence indicated that the EAG was a true measure of male olfactory response, and variations in age, light intensity, and time of day did not affect antennal responsiveness to sex pheromone, although the same variables had an effect on the behavioural responsiveness of intact male moths. Expand
Sex Pheromones of Noctuid Moths. XIII. Changes in Pheromone Quantity, as Related to Reproductive Age and Mating History, in Females of Seven Species of Noctuidae (Lepidoptera)
The occurrence of a single mating on the third night following emergence did not cause a rapid disappearance of sex pheromone among 5 species studied, consistent with the fact that females of many noctuid species commonly mate more than once. Expand
A high-efficiency collection device for quantifying sex pheromone volatilized from female glands and synthetic sources
A high-efficiency collection device for sex pheromones volatized from forcibly extruded female glands is described and small quantities of distilled carbon disulfide are used to rinse the glass wool. Expand
Sex Pheromones of Noctuid Moths. X. The Morphology and Histology of the Female Sex Pheromone Gland of Trichoplusia ni (Lepidoptera: Noctuidae)
The gland that produces the female sex pheromone of Trichoplusia ni (Hubner) is an eversible sac of glandular epithelium situated dorsally in the intersegmental membrane between the eighth and ninthExpand
Sex Pheromones of Noctuid Moths. XXVI. Female Release Rate, Male Response Threshold, and Communication Distance for Trichoplusia ni,
About half of the sexually mature virgin females of Trichoplusia ni Hubner observed in the laboratory released sex pheromone on any given night, and these data are used to estimate potential female to male communication distances in the field. Expand
