“…Moreover, by the time a male locates a female colony, the females have aged and their fecundity has deteriorated (Fitzpatrick, ; Ross et al., ). In fact, it was suggested that moth (Harari et al., ) and P. ficus (Walton et al., ) fertile females deposit fewer eggs in MD plots. Finally, Jones & Aihara‐Sasaki () have proposed a synergetic effect between decreased oviposition and delayed mating, as older females may die before laying their full egg complement.…”

The vine mealybug, Planococcus ficus (Signoret) (Hemiptera: Pseudococcidae), is a major pest of vineyards. Here, we tested the efficacy of the mating disruption method against the pest when applied during one or two successive years in high and low infestation levels. Following 1 year of treatment, at low initial infestation levels a shutdown of pheromone traps was observed, along with a significant reduction in infested vines. With initially high infestation levels, a gradual reduction in infested vines was observed, with a trap shutdown seen only after the second year of pheromone application. We discuss the implications of the male mating disruption method for this pest in which the wingless females are aggregated with limited movement among vines, offering multiple mating opportunities for the flying male.

“…Thus, a great deal more research needs to be carried out, examining a range of species with a variety of biological traits (e.g., monandrous and polyandrous, host-plant specialists and generalists, migrants and non-migrants) to determine whether any general rules exist. It is also important from an applied perspectiveautodetection may be an overlooked factor affecting the efficacy of mating disruption programs (Stelinski et al, 2006;Harari et al, 2015).…”

Changes in female calling behavior in response to the presence of conspecific pheromones (pheromone autodetection) have been demonstrated in a number of moth species. However, the observed changes vary between species, and several ecological and adaptive explanations for autodetection have been proposed. We studied the effect of conspecific females on the calling behavior of the noctuid moth Pseudaletia adultera (Schaus) (Lepidoptera: Noctuidae, Hadenini), by comparing the age of first calling, as well as the onset and pattern of calling, when females were held individually or in the presence of conspecifics. Grouped females started calling at a lower age, a higher percentage of females called during the scotophase, and they called longer compared to females held in isolation. We also demonstrated that female antennae respond to each of the three main components of the sex pheromone – (Z)‐11‐hexadecen‐1‐ol, (Z)‐11‐hexadecen‐1‐yl acetate, and (Z)‐11‐hexadecenal – and that the response patterns differed from those of male antennae. By calling more and extending her calling window in presence of conspecific females, a female may increase her chances of accessing males. However, the potential benefits need to be considered within an ecological context, considering factors such as migration, oviposition, and foraging.

“…This result is consistent with previous research in apple orchards (Li et al ., ). Mating disruption is an environmentally safe pest control method that has allowed growers to reduce insecticide use significantly (Harari et al ., ). However, the main problem was maintaining the lures effectively and reducing the cost of lures and distribution (Gaston et al ., ).…”

Increased trapping efficiency for the peach fruit moth Carposina sasakii (Matsumura) with synthetic sex pheromone

Carposina sasakii Matsumura is one of the most serious fruit‐damaging pests in Southern East Asia. The management of C. sasakii using sex pheromones has proven to be simple, effective and environmentally friendly with respect to monitoring and controlling this pest. To apply sex pheromone‐based pest control techniques effectively, we characterized a range of application parameters, as well as the effects of synthetic sex pheromones, in jujube orchards. Trapping radius was determined by comparing the mean number of trapped individuals at different inter‐trap distances, and mating disruption parameters were inferred by comparing the rate of trapping efficiency reduction and the infestation ratio of fruits in the experimental fields by uniformly placing different number/types of lures/100 m2. These studies revealed capture rates with significant differences across 10–50‐m inter‐trap distances: for example, a 30‐m or greater inter‐trap distance was suitable for monitoring and mass trapping, whereas distances <20 m significantly decreased the trapping efficiency in the testing area. The studies lay the foundation for the implementation of these technologies within the context of a well‐conceived control strategy against this significant agricultural pest.

Female detection of the synthetic sex pheromone contributes to the efficacy of mating disruption of the European grapevine moth, Lobesia botrana

Abstract: In addition to reducing the ability of males to locate females, the mating-disruption technique can suppress pest numbers as a consequence of its direct effects on females. The two mechanisms probably act synergistically.
