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.

Single Factor Experiment

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.

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.

AbstractThe female sex pheromone gland of Diparopsis castanea Hmps. consists of modified intersegmental tissue between the eighth and ninth abdominal segments. Glands contain an average of 12·73 ×10–3 μg of pheromone consisting of 80·4±2·0% trans-9, 11-dodecadien-l-yl acetate (range 72·7–86·7%) and 19·6±2·0% 11-dodecen-l-yl acetate (range 13·3–27·3%). Although no significant correlation exists between female body weight and pheromone content of the gland, the duration of sex pheromone release over the lifespan of a female is positively correlated with its weight on emergence. Six behavioural steps may be recognised in the precopulatory behaviour of females but the frequency and duration of sex pheromone release is strongly influenced by both temperature and light intensity. At 25°C females typically ‘call’ on two or more occasions for 41–50% of the night, calling commencing earlier at cool (13·4°C) temperatures than at moderate (19·4°C) or warm (25·0°C) temperatures. Calling by mated females increases considerably from four to five nights after mating but is typically of shorter duration than for virgins. The dispersal flight of Diparopsis males in cotton crops commences almost immediately after sunset and before the end of dusk, with peak male catches in sex pheromone traps occurring earlier in the cooler months of May and June (20.00–22.00 h) than in November (02.00–04.00 h). The Diparopsis synthetic sex pheromone, dicastalure, traps a greater proportion of males and females both earlier and later in the night than virgin females and this ‘timing advantage’ may be important in a pheromone control programme based on disruption of communication between the sexes.
