A series of laboratory and field experiments were performed to assess the responses of Tribolium castaneum (Herbst) and other stored-product beetles to pheromone-baited traps and trap components. A commercial Tribolium pitfall trap called the Flit-Trak M2, the predecessor to the Dome trap, was superior in both laboratory and field experiments over the other floor trap designs assessed at capturing walking T. castaneum. In field experiments, Typhaea stercorea (L.) and Ahasverus advena (Stephens) both preferred a sticky trap to the pitfall trap. Although the covered trap is effective at capturing several other species of stored product beetles, the synthetic Tribolium aggregation pheromone lure is critical for the pitfall trap’s efficacy for T. castaneum. Although the food-based trapping oil used in the pitfall trap was not found to be attractive to T. castaneum when assayed alone, it had value as an enhancer of the pheromone bait when the two were used together in the trap. A dust cover modification made to go over the pitfall trap was effective in protecting the trap from dust, although the trap was still vulnerable to dust contamination from sanitation techniques that used compressed air to blow down the mill floors. Capture of T. castaneum in the modified trap performed as well as the standard trap design in a non-dusty area of a flour mill, and was significantly superior over the standard trap in a dusty area. T. castaneum responded in flight outside a flourmill preferentially to multiple funnel traps with pheromone lures compared to traps without pheromone.

Stikem-coated traps constructed from 5-gallon plastic cans and baited with virgin females of Diatraea saccharalis (F.) were more effective in recapture of males than comparable wire traps. Percent recapture for males released at 120 feet, 180 feet, and 220 feet from traps baited with virgin females were 18.6, 23.0 and 24.3 percent, respectively. Higher numbers were recaptured when males were released upwind from pheromone traps than when releases were made downwind, thus indicating that the male response to the pheromone may be through chemical olfactory receptors. Cool temperatures, arthropod predation and poor trap design can be responsible factors for inefficient recapture of released males.

AbstractSix pheromone trap designs, including five high-capacily and a sticky trap, and four PVC lure concentrations of pheromone were evaluated for monitoring blueberry leaftier populations in six blueberry fields in Nova Scotia. Larval densities and subsequent male moth catches in the same year for all the trap designs evaluated, except double funnel traps, were highly correlated. Multipher III traps captured the highest number of moths, followed by Unitraps and double funnel traps. The ice cream container trap captured significantly fewer moths than any other trap design. At most locations, the first moth was caught on the same day in all the trap designs except the ice cream container trap. Trap catches increased with increasing pheromone concentration up to 0.03% dose. Traps baited with 0.3% lures captured significantly fewer moths than those with 0.003% or 0.03%. Based on mean trap catches, R2 values, coefficients of variation among traps, trap efficiency, and lure evaluations, the Unitraps baited with 0.003% lures are selected for further development of a population monitoring system for blueberry leaftier moths. The Multipher III traps baited with 0.03% lures captured up to 44 000 male moths (mean per trap per season) at high densities, demonstrating their potential in mass trapping blueberry leaftiers.

Abstract The use of aerosol mating disruption for management of the navel orangeworm Amyelois transitella (Walker) in California tree nuts has increased markedly. This treatment suppresses pheromone monitoring traps in neighboring orchards as well as in the orchard under treatment. The current study, therefore, addresses the interrelated topics of which attractant is most effective, how the number of adults captured is affected by trap design, and what sex is captured. Under most circumstances, wing traps baited with phenyl propionate (PPO) captured more adults than those baited with a 5-compound kairomone blend. Adding a pheromone lure along with the dispenser for the experimental attractant increased the number of adults captured with PPO both in and near-mating disruption. In contrast, addition of a pheromone lure along with the kairomone blend only increased the number of adults captured in orchards near but not under mating disruption. Delta traps, which are preferred by the industry, captured fewer adults than wing traps. Improvements in the number of adults captured with PPO in delta traps from addition of a pheromone lure and from design modifications were additive. Both sexes were captured by all attractants and trap designs tested, and the sex ratio was highly variable. Open traps like the wing trap captured a slightly higher proportion of males than closed traps. These findings are discussed in the context of management of the navel orangeworm.

AbstractThree suitable sex pheromone trap designs for trapping the red bofiworm of cotton, Diparopsis castanea Hmps., including a simple omnidirectional monitoring trap, are described. In trials in Malawi, Diparopsis was more readily trapped on open horizontal trapping surfaces (water or adhesive) than in enclosed types of traps. The presence of a roof above the trapping surface, at spacings of up to 20 cm, significantly reduced catches. White traps, or unpainted traps in the case of vane traps constructed from galvanised metal, caught more moths than traps of other colours. Catches were greatest when monitoring traps in cotton were placed at ground level or at a height of 0·5 m and, when dicastalure was released from polyethylene vials, by employing a trap 60 cm in diameter. Evidence was obtained that competition may exist between female-baited traps spaced up to 73 m apart, although catches in traps baited with dicastalure were not significantly different when traps were 40–60 m apart. The greatest catches of moths in cotton were in traps located in insecticide-sprayed fields, but moths were also trapped in considerable numbers in other crops and to a reduced extent in open areas 4·8 km from the nearest cotton. From about the end of February, catches in maize, groundnut and fallow areas frequently exceeded the catches recorded within cotton fields, which may indicate an increased dispersal flight from cotton by adult moths later in the season. Weekly replacement in monitoring traps of polyethylene vials containing dicastalure produced maximum moth catches, but there was no significant difference in catch between traps in which pheromone was replaced at intervals of 2, 3, 4 or 6 weeks.

Almond Moth

The effect of the presence of the Indianmeal moth, Plodia interpunctella (Hübner), on the capture of the almond moth, Cadra cautella (Walker), in pheromone-baited traps was evaluated. It was found that when both sexes of each species were released into a large warehouse simultaneously, the capture of male C. cautella was reduced to 5.5 ± 0.8 in traps baited with a two-component lure as compared to 11.4 ± 2.2 when only C. cautella were released. This decrease in response may have been caused by an inhibitory substance produced by the female P. interpunctella that affects the response of male C. cautella to the pheromone or confusion caused by an increase in the amount of pheromone present. This reduced response of C. cautella must be considered when using pheromone-baited traps to estimate population levels when both species are present.
