“…In pest management, volatile sex pheromones are commonly applied to trap and monitor lepidopteran and coleopteran pest species and to disrupt their communication (Arakaki et al 2008, Vacas et al 2011. Jewett and Carpenter (1998) hypothesized that sex pheromones could also be used to monitor the occurrence and density of natural pest enemies, including parasitoids, and to assess the optimal timing of additional releases.…”

Polyphagous solitary parasitoids have difficulty finding mates that can be widely dispersed because of their polyphagous natures. Males of polyphagous species are more likely to rely on compounds characteristic of the female or on sex pheromones to find mates. However, the mating biology of few polyphagous parasitoids has been studied and sex pheromones are known for only a few species of parasitoids altogether. Here we examined the mating biology of the polyphagous parasitoid Itoplectis naranyae Ashmead (Hymenoptera: Ichneumonidae), which attacks a variety of lepidopteran pupae. The existence and timing of emission of female sex pheromones and male response with age were studied in the laboratory. A field test was also conducted to confirm the attractiveness of newly emerged females to wild males over a distance. The results confirmed that volatile compounds are used in the sexual communication in I. naranyae. Females attracted males most strongly shortly after emergence; pupae and older females were much less attractive. Older (30-d-old) males were most responsive to female sex pheromones. Males with prior experience with females responded more strongly than naïve males. The field test showed that traps containing virgin females attracted wild males. These results showed that this solitary polyphagous species uses volatile compounds to find scattered mates at close and moderate ranges. The existence of chemically mediated mate finding suggests that sex pheromone traps may be useful in management of I. naranyae as a biological control agent.

“…It has been reported that the lobesia borana female could release about 0.3 ng h −1 sex pheromone 16 and we assume that it could release about 0.3 ng h −1 × 2 h × 7 d ≈ 0.0042 μ g wk −1 . The optimum release rate for lobesia borana in the field had been reported as 2800 μ g wk −1 (400 μ g d −1 ) 17 . Those results suggested that the artificial sex pheromone released from dispenser should reach approximately 6.6 × 10 5 times of the female's could outcompete female moth.…”

For successful pest management, codlemone (E, E-8,10-dodecadien-1-ol) is widely used to monitor codling moth. The pheromone release rate is essential for the lure's attractiveness. The optimal sex pheromone release rate (V 0 ) for trapping codling moth was evaluated during 2013-2014. The overwinter generation V 0 was 6.7-33.4 μg wk −1 , and moth catches (MCs) were 0.82 ± 0.11 adults/trap/week; MCs for lower (V 1 ) and higher (V 2 ) release rates were 52.4% and 46.3%, respectively, of that for V 0 . The first generation V 0 was 18.4-29.6 μg wk The codling moth, Cydia pomonella (L.) (Lepidoptera: Tortricidae), is an important pome fruit pest all over the world and causes serious damage to apple (Malus domestica Borkhausen), pear (Pyrus communis L.) and walnut (Juglans regia L.) 1,2 . It is not only an invasive species but also an important quarantine pest in China. To date, the codling moth has been found in 7 provinces in China, including Xinjing, Gansu, Ningxia, Inner Mongolia, Heilongjiang, Jilin and Liaoning, posing a grave threat to the two major apple production areas in China, Shandong and Shanxi provinces 3 . Trapping the male codling moth using its sex pheromone (codlemone, E, E-8, 10-dodecadien-1-ol) is the most successful technique for the monitoring of this species. The initial loading rate is an important criterion for the manufacture of dispensers and has been widely studied. A commonly used loading rate for codling moth monitoring is 1 mg sex pheromone [4][5][6] . However, the same loading rate may have different release rates due to the use of different dispenser materials and/or under different environmental conditions, leading to different trapping efficiencies. Therefore, the loading rate is not a reasonable criterion to use to evaluate whether a sex pheromone dispenser performs well. Whatever dispenser is used, the amount of sex pheromone released to the surrounding air per unit time (sex pheromone release rates) is the key factor that determines adult catches. The pheromone release rate that achieves maximum moth catches is termed the optimal sex pheromone release rate (V 0 ). V 0 can catch significantly more adults than lower (V 1 ) or higher (V 2 ) release rates.A previous study has reported the response of the codling moth to different release rates of codlemone in the field in its native distribution area, Spain. At a range of 11-1078 μ g d −1 (77-7546 μ g wk), the pheromone release rate of 11-67 μ g d −1 (77-469 μ g wk −1 ) achieved the maximum male catches 7 . However, as an invasive pest in China, the codling moth has experienced a long period of diffusion and dissemination, adapting to various ecological environments and diversified host plants, which leads to different V 0 for its trapping. In addition, the previous study 7 did not use pheromone release rates < 77 μ g wk −1 and did not consider studying different generations.

“…Pheromone-baited traps are employed to detect adult males of this pest and to monitor them, while mating disruption techniques have been extensively used for population control (Witzgall et al , 2005; Vacas et al , 2011); capture of the males figuring among the best means of monitoring adult phenology throughout the season (Anshelevich et al , 1994; Witzgall et al , 2000; Anfora et al , 2005). Control of eggs and young larvae by chemical treatments or insecticides containing Bacillus thuringiensis toxins (Ruiz de Escudero et al , 2007), or regulation by natural enemies (Xuéreb & Thiéry, 2006) have also been described.…”

Lobesia botrana is the most significant pest of grape berries in Spain. Further knowledge of its phenology would enable wine growers to decide on an optimal treatment schedule. The aim of this study is, therefore, to predict the flight peaks of L. botrana in seven wine-growing regions of Spain. The main goal is to provide a prediction model based on meteorological data records. A logistic function model, based on temperature and humidity records, together with an exhaustive statistical analysis, were used to compare the wine-growing regions in which the male flight phenology of L. botrana displays similar patterns and to sort them into groups. By doing so, a joint study of the dynamics of the moth is possible in the regions within each group. A comparison of the prediction errors before and after applying the Touzeau model confirmed that the fit of the latter model is not sufficiently accurate for the regions under study. Moth flight predictions with the logistic function model are good, but accuracy may still be improved by evaluating other non-biotic and biotic factors.
