AbstractTraps baited with the sex pheromone of the bertha army worm moth, Mamestra configurata (Walker), were operated at 36 sites across the prairie provinces in 1976 and 1977. They captured ca. 15 times as many bertha moths as did light traps and were considered to constitute a useful method for detection of adults of this species.

AbstractEfficiencies of light and pheromone traps were estimated from captures of moths emerging from pupae in the center of circular arrays of traps up to 200 m in radius. Light traps captured 1 insect for every 3.6 that passed through a linear meter at the trap, an efficiency factor of 0.28. This factor was constant for different insect densities. The pheromone traps were 3.5 times as efficient as light traps based on the captures of males only. The low efficiencies imply that the traps have a small zone of influence and several may be needed in a limited area to produce catches within reasonable confidence limits when populations are sparse and detection of increasing numbers has the greatest value.

AbstractInclusion of traces of (Z)-11-hexadecenol in synthetic sex lure traps for bertha armyworm moths resulted in diminished trapping; substantial amounts of (Z)-9-hexadecenol or (Z)-11-hexadecenal were also suppressant. Of 22 other oxyolefins tested, (Z)-7-dodecenyl acetate acted in conjunction with the bertha lure components to attract Euagrotis tepperi (Walker) to traps, and (Z)-7-tetradecenyl acetate similarly to attract Lacinipolia vicina (Grote). No tested additive improved either the potency or the specificity of the original bertha blend.

AbstractAthrycia cinerea (Coq.) is a univoltine parasite of bertha armyworm, Mamestra configurata Wlk., on rapeseed in the Prairie Provinces of Canada. Details of the parasite’s seasonal life history are presented. Females oviposit on third, fourth, fifth, and sixth instars of bertha armyworm, and the parasite larvae usually develop gregariously and mature on the fifth and sixth instars. Supernumerary parasite larvae on superparasitized hosts starve; surviving larvae develop more rapidly, form smaller pupae with a lower capacity for survival, and eventually produce a consistently though not significantly smaller percentage of female adults than parasites that develop on non-superparasitized hosts. Larvae of A. cinerea are often killed if they compete with larvae of Banchus flavescens Cress., the only other common parasite of bertha armyworm, and a small percentage of the pupae of A. cinerea are killed by a hyperparasitic ichneumonid, Phygadeuon subfuscus Cress.

AbstractA potent sex pheromone produced by female bertha army worm moths was isolated. A 16 carbon, unsaturated, alkenol acetate was indicated from chemical degradative and GLC retention data. The location and configuration of the double bond was determined from the antennal responses (EAG) of male moths to a series of cis and trans mono-unsaturated alken-1-ol acetates; cis-11-hexadecen-1-ol acetate elicited the greatest EAG response. GLC retention times of the purified insect sex pheromone corresponded exactly with those of authentic cis-11-hexadecen-1-ol acetate on several analytical columns. Maximum biological response in laboratory bioassays of synthetic materials was obtained from a mixture of approximately 85% cis- and 15% trans-11-hexadecen-1-ol acetates.

AbstractA sex pheromone, detected in female moths of the bertha armyworm, Mamestra configurata Wlk., was extracted from females that were more than 3 days old. Males responded to the pheromone from 2 days of age until they died; younger males were not tested. Chemical and bioassay analyses indicated that the pheromone was an acetate.The stimulatory effect of several chemicals was determined with males in a laboratory bioassay. Sexual responses were induced by Z7-, Z9-, Z10-, Z11-, and Z13-hexadecen-1-ol acetates. The maximum response in the laboratory was from the Z10-isomer, but this compound was only weakly attractive to males in the field.
