These data indicated that aldicarb degraded quite rapidly in the selected soils and most of the applied radioactivity volatilized from these soil columns as14CO2. The evolution of14CO2 from the treated soil suggested severe degradation of the aldicarb molecule and consequently provided indirect evidence against the accumulation of significant quantities of toxic metabolites in the soil types evaluated. Under field conditions this toxicant appeared to have a half-life of about 7 days in loam soil.Type of Medium: Electronic ResourceURL: -

ISSN: 1573-1561Keywords: Corn earworm ; Heliothis zea ; Lepidoptera ; Noctuidae ; pheromone ; (Z)-11-hexadecen-1-ol ; laboratory rearingSource: Springer Online Journal Archives 1860-2000Topics: BiologyChemistry and PharmacologyNotes: Abstract Analysis of ovipositor extracts of lab-reared (〉 120 generations) and wildHeliothis zea indicated small but significant differences in the percent composition of the four aldehyde components of the sex pheromone. (Z)-11-hexadecen-1-ol (Z11–16∶OH) was present in both populations and amounted to only 2.8% of the total pheromone. There was no significant difference in four of the six behavioral categories between lab-reared and wild males exposed to the four-component sex pheromone in the flight tunnel. Ninety and 84% males flew to the pheromone source, respectively. However, with the addition ofZ11–16∶OH to the pheromone blend, none of the wild males flew upwind to the stimulus source, whereas 36% of the lab-reared males completed the flight. It is suggested that prolonged inbreeding in closed quarters rendered these males less discriminating to qualitative differences in a pheromone blend.Type of Medium: Electronic ResourceURL: -

La période à laquelle sont placés les cocons deC. melanoscela sur le terrain a une forte influence sur le nombre deC. melanoscela qui survivent et émergent en tant qu'adultes en même temps que les premiers stades sensibles deLymantria dispar. La proportion des adultes ayant émergé qui sont disponibles pendant la période où l'hôte est dans un stade sensible varie de 1 à 92 %, selon les dates des lâchers. Novembre et décembre sont les deux mois les plus favorables pour placer les cocons deC. melanoscela avec une émergence des adultes de 74 à 92 % au moment des pics de stades hôtes sensibles. C'est au printemps que les lâchers étaient les moins efficaces. Les causes d'innefficacité, variables selon les lieux et les dates, on été: les pertes durant les manipulations, l'abscence d'émergence, l'hyperparasitisme, la prédation et l'émergence d'adultes deC. melanoscela à des périodes où les stades sensibles de l'hôte ne sont pas disponibles. Les lâchers de novembre et décembre permettent d'éviter l'attaque des ennemis naturels et sont suivis par l'entrée en diapause et un développement post-diapause qui favorisent la survie et la synchronisation de l'émergence des adultes avec les stades hôtes réceptifs.Notes: Abstract Cohorts ofCotesia melanoscela (Ratzeburg) (Hymenoptera: Braconidae) cocoons were exposed in the field at three Maryland locations to attack by natural enemies for two week periods, then were held in an outdoor insectary untilC. melanoscela adult or hyperparasitoid emergence. The timing of placement of theC. melanoscela cocoons in the field had a profound effect on the number ofC. melanoscela that survived and emerged as adults in synchrony with the field occurence of susceptible early-instarLymantria dispar (L.) larvae. The proportion of emerged adults available during susceptible host stages ranged from 1–92%, depending on dates of release. November or December placements ofC. melanoscela cocoons were most effective with 74–92 % emergence of adults during peak periods of susceptible host stages. Spring placements were least effective. The causes of ineffective placement, which varied with location and with date, were program (handling) loss, non-emergence, attack by hyperparasitoids, predation, andC. melanoscela adult emergence at times when appropriateL. dispar life stages would not be present. We concluded that November/December releases avoided natural enemies and promoted appropriate diapause and post-diapause development that enhanced survival and synchrony of adult emergence with host stage susceptibility.Type of Medium: Electronic ResourceURL:
