“…Delayed mating has a strong influence on the growth rate of multivoltine populations because the preoviposition period is extended and, consequently, the mating age is raised. For example, mating delay of 4–6 d caused a significant reduction of the population growth rate in the koa seedworm, Cryptophlebia illepida (Butler), although the percentage of mated females did not differ between control and delayed treatment ( Jones and Aihara-Sasaki 2001 ). …”

Mating disruption field experiments to control the vine mealybug, Planococcus ficus (Signoret) (Hemiptera: Pseudococcidae), were carried out in 2008 and 2009 in two commercial vineyards in Sardinia (Italy). The effectiveness of mating disruption was evaluated by testing reservoir dispensers loaded with 100 mg (62.5 g/ha) and 150 mg (93.8 g/ha) of the sex pheromone in 2008 and 2009, respectively. The number of males captured in pheromone traps, the P. ficus population density and age structure, the parasitism rate, the percentage of ovipositing females, and the crop damage were compared between disrupted and untreated plots. In both field trials, the number of males captured in mating disruption plots was significantly reduced by 86% and 95%, respectively. Mating disruption at the initial dose of 62.5 g/ha of active ingredient gave inconclusive results, whereas the dose of 93.8 g/ha significantly lowered the mealybug density and modified the age structure, which showed a lower percentage of ovipositing females and a higher proportion of preovipositing females. Mating disruption did not affect negatively the parasitism rate, which was higher in the disrupted than in the control plots (>1.5-fold). Crop damage at harvest was very low in both field trials and did not differ between treatments. Mating disruption was effective in wide plots protected with dispensers loaded with 150 mg of the sex pheromone, showing its potential to be included in the overall integrated control programs in Mediterranean wine-growing regions.

“…Alternative mechanisms are being explored that focus on the effects of delaying mating rather than its complete suppression. Delays in mating by virgin females or males has been shown in multiple species to result in depressed egg-laying and increased sterility of the eggs laid (Jones and Aihara-Sasaki 2001;Fadamiro and Baker 1999). Therefore, exclusive focus on the complete prevention of mating may not be warranted.…”

“…Pheromone-mediated mating disruption may not always prevent mating of the target pest but can delay mating behavior so that the fitness and subsequent population dynamics of the insect are impacted (Jones & Aihara-Sasaki, 2001;Baker & Heath, 2005). Delayed mating is postulated to be one of the ways mating disruption treatments can regulate population growth of the targeted species (Barclay & Judd, 1995;Baker & Heath, 2005;Jones et al, 2008).…”

When mating disruption does not disrupt mating: fitness consequences of delayed mating in moths

The goals of pheromone-mediated mating disruption are to interfere with mate finding, suppress insect population growth, and prevent crop damage. In addition to prevention of mating, pheromone treatment can also result in a delay of mating so that the fitness and subsequent population dynamics of the target insect pest are impacted. Females have a limited time to mate, mature eggs, and find suitable oviposition hosts, and a delay in mating can have large consequences on female fitness. As a result, delayed mating could be considered an indirect method by which mating disruption works to control pest populations. We perform a metaanalysis on 24 experimental studies to assess the consequences of delayed mating on female moth fecundity, egg fertility, adult longevity, and pre-oviposition period. Our goal is to determine whether the effect of delayed mating on female moth fitness is influenced by the following explanatory variables: moth family, voltinism, larval diet breadth, adult dispersal capacity, female mating strategy, and egg development strategy. Across species, the effect of delayed mating on female moths significantly decreases fecundity, fertility, and pre-oviposition period and increases female longevity. The effect of delayed mating on female fitness is only marginally affected by the explanatory variables tested. We discuss the observed patterns and argue that delayed mating can be an important method by which population regulation is achieved through pheromonemediated mating disruption. Finally, we highlight areas where future research could add to the growing body of knowledge on mating disruption-imposed delayed mating of female moths.
