Management of western bean cutworm Striacosta albicosta (Lepidoptera: Noctuidae) and mycotoxins in Ontario maize

Mating status regulates post‐mating refractory period in Striacosta albicosta females

The earlier onset of calling by previously mated females could reduce competition with virgin females and their shorter refractory period could explain the high incidence of polyandry observed in nature.

This book explains why females mate more than once, and discusses interspecific signal competition, selection, and choice in the courtship and courtship of females and males.

CALLING BEHAVIOR OF TWO DIFFERENT FIELD POPULATIONS OF PHYLLOCNISTIS CITRELLA (LEPIDOPTERA: GRACILLARIIDAE): EFFECT OF AGE AND PHOTOPERIOD

To determine patterns of calling of two populations of P citrella when exposed to three different photoperiods as a first step toward determination of a specific sex pheromone, differences in percentages of female calling were subjected both to G-test and two-way ANOVA.

Impact of Photoperiod on the Sexual Behavior of the Black Cutworm Moth (Lepidoptera: Noctuidae)

Although photoperiod length can influence calling, pheromone production, and male response, it has little effect on the age at which A. ipsilon reach sexual maturity, which cannot explain the delayed maturity observed in the field.

Western Bean Cutworm, Loxagrotis albicosta (Lepidoptera: Noctuidae): Female Sex Pheromone Identification

Results indicate that the olefinic compounds identified from the ovipositor extract represent the female sex pheromone complement of the species.

It is suggested that X‐linkage of genes influencing PCP may reduce the genetic load associated with this polymorphism by reducing the frequencies of inappropriate PCP genotypes in these summer populations, in autumn when winds are predominantly northerly, fewer individuals at any latitude will lack the capability to make the return journey southward.

ASPECTS OF MATING IN THE SPRUCE BUDWORM, CHORISTONEURA FUMIFERANA (LEPIDOPTERA: TORTRICIDAE)

Normal matings of Choristoneura fumiferana (Clem.) resulted in the transfer of single, persistent spermatophores, and the presence of a sperMatophore in the bursa of the female was not always indicative of successful insemination.

Attraction of male turnip mothsAgrotis segetum (Lepidoptera: Noctuidae) to sex pheromone components and their mixtures at 11 sites in Europe, Asia, and Africa

Differences in male attraction among the populations studied confirm the existence of significant population variation in the pheromone of A. segetum, and Interpretation of the present results suggests that this variation is more or less continuous in Eurasia and north Africa, while a clearly distinct phersomone type is present in the areas south of the Sahara desert.

An Evaluation of Western Bean Cutworm Pheromone Trapping Techniques (Lepidoptera: Noctuidae) in a Corn and Soybean Agroecosystem

Results show that trapping techniques do affect trap catches and that either trap type placed between two cornfields at either 1.2 or 1.8 m above the ground will maximize trap catches.

Age-related calling behavior of the black cutworm, Agrotis ipsilon

As moths aged, calling commenced earlier in the scotophase, with 4-dayold females calling earliest, thus, sexually mature moths are more competitive than their younger counterparts by calling and attracting males first.

Evidence of a Sex Pheromone in the Omnivorous Leaf Roller, Platynota stultana (Lepidoptera: Tortricidae): Laboratory and Field Testing of Male Attraction to Virgin Females

Laboratory and field tests conducted with virgin females of the omnivorous leaf roller moth, Platynota stultana Walsingham, demonstrated the presence of a female sex attractant in this insect. Males
