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

Abstract

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.

Molecular characterization and functional analysis of pheromone binding proteins and general odorant binding proteins from Carposina sasakii Matsumura (Lepidoptera: Carposinidae)

“…22 Although the ratio of composition in the two pheromones varies geographically, the common theme is that Z-7-eicosene-11-one play a dominant role in the sex pheromone. 23,24 However, their application to pest control is limited by cost and the complexity of their structure, and many studies have focused on the artificial synthesis of these chemicals. 25 But, as we now know, the volatile compounds released by plants and sex pheromones often play coordinated roles in the natural environment.…”

“…Previous studies have shown that the mainly sex pheromones for Carposina sasakii are Z ‐7‐eicosene‐11‐one and Z ‐7‐nonadecene‐11‐one .

Field trials of synthetic sex attractants of Illiberis pruni in China

“…Our results suggest that traps placed >25 m apart catch more moths than those placed 5 and 15 m apart. When traps are placed close to each other, their radius of attraction may overlap (Wall & Perry, 1978;Bacca et al, 2006;Kong et al, 2014;Liu et al, 2015;Zhang et al, 2017).…”

Identification and expression patterns of candidate carboxylesterases in Carposina sasakii Matsumura (Lepidoptera: Carposinidae), an important pest of fruit trees

“…The peach fruit borer Carposina sasakii Matsumura (Lepidoptera: Carposinidae) is an important pest that seriously damages fruit trees such as apples, pears and jujubes in a large area of Asia (Zhang et al ., 2017 a ), with a damage rate of fruits up to 80% or more (Li et al ., 2013). The adults mainly depend on olfaction to communicate with the environment.…”

“…The adults mainly depend on olfaction to communicate with the environment. C. sasakii adult females release (Z)-7-nonadecen-11-one and (Z)-7-eicosen-11-one as sex pheromone to attract the adult males for mating (Han et al ., 2000; Zhang et al ., 2017 a ). Nine carboxylic esters from apple fruits attract C. sasakii adult females or elicit their olfactory physiological responses, which may help the adult females choose oviposition sites (Wang et al ., 2011; Sun and Wang, 2015).…”
