AbstractThe efficiency of two sticky-bottomed traps and seven high-capacity, nonsticky traps in catching male spruce budworm [Choristoneura fumiferana (Clem.)] moths was evaluated in a wind tunnel. The place where the male moths first contacted the trap, the length of time that passed until they entered the trap, and the number remaining in the trap after 5 min were recorded. The most efficient traps were the Pherocon 1 C, a sticky-bottomed trap, and the Multi-Pher and Uni-trap, both nonsticky traps with internal funnel-shaped baffles that prevent moths from escaping. As sticky traps become saturated at relatively low densities they are not suitable for monitoring wide changes in population density. The Multi-Pher and Uni-trap are therefore recommended for monitoring population changes of the spruce budworm, establishing thresholds for management action, and estimating population density.

AbstractPheromone traps were more efficient than blacklight traps for detecting and monitoring adult populations of fall armyworm, Spodoptera frugiperda (J.E. Smith), in southwestern Ontario. Several dispenser–chemical combinations were strongly attractive but best results were obtained with sticky traps baited with rubber septa impregnated with combinations of (Z)-9-dodecenyl acetate and (Z)-9-tetradecenyl acetate.

AbstractExperiments in Malawi over several seasons indicated that use of sex pheromone baited traps would be an unsatisfactory method for the more efficient timing of insecticide applications against Diparopsis castanea Hmps. Excessive temporal and spatial variation between catches of male moths in pheromone traps and corresponding oviposition by females on cotton renders the method unreliable. Experiments indicated, however, that fewer sprays of insecticide against Diparopsis could be applied without significant loss of yield or quality by spraying when the numbers of eggs of Diparopsis reached 0·25/plant. It is suggested that modification of the existing method of egg scouting on plants offers the best prospect for efficient control of Diparopsis concomitant with the increasing demand by farmers for reduced spraying.

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.

The research was carried out to determine the appropriate number of sex pheromone traps for monitoring the Spodoptera exigua moths in shallot crop which was grown in Yogyakarta Special Territory, Bantul Regency (Samas). This research was conducted in August until September 2016. Sex pheromone trap was arranged on shallot aged  3 weeks after planting. Sex pheromone trap with hexadecenat tetra asetat ingredients was placed on sticky yellow trap. This research  used RCBD experimental design with single factor experiment namely the number of trap i.e. 3, 5, 6, 8 units/2.000 m2 with sex pheromone, and  three traps without sex pheromone as control. Each treatment was repeated 5 times so  125 samples of experiments were obtained. Observation was made by counting the number of moths caught in sex pheromone trap. The result of observation was analysed  with analysis of variance (ANOVA) and DMRT α 5.0%. The results show that the appropriate number of trap to monitor the pest infestation was 3 units/2.000 m2.
