A multi-species pheromone lure: A blend of synthetic sex pheromone components for two mirid species, Stenotus rubrovittatus (Matsumura) and Trigonotylus caelestialium (Kirkaldy) (Heteroptera: Miridae)

Abstract

Two mirid bugs, Stenotus rubrovittatus (Matsumura) and Trigonotylus caelestialium (Kirkaldy) (Heteroptera: Miridae), are sympatric pests that infest rice in many regions of Japan. Three components, hexyl butyrate, (E)-4-oxohex-2-enal and (E)-hex-2-en-1-yl butyrate, in S. rubrovittatus and three other components, hexyl hexanoate, (E)-hex-2-en-1-yl hexanoate and octyl butyrate, in T. caelestialium, were identified as sex attractant pheromone components in these species. The synthetic pheromone lures for S. rubrovittatus do not attract T. caelestialium and vice versa. The attractiveness of the combination of two separate lures for the two mirid bugs within one trap (combination lures) and the attractiveness of a mixed lure, in which all six synthetic-pheromone components of both species were loaded onto a single septum, were compared with that of separate lures for each species in field experiments. Both the combination lures and the mixed lure were as attractive to males of both mirid bugs as the separate lures for each species in fields with gramineous plants. In paddy fields, the mixed lure was also as attractive to males of both species of mirid bugs as the separate lures for each species. These results suggest that the mixed lure and the combination lures could be useful as simultaneous monitoring tools for two sympatric major rice pests using a single trap.

Sex pheromone of Nearctic Agriotes mancus and its similarity to that of three Palearctic Agriotes invasive in North America

“…Combining the sex pheromones of multiple elaterid species in a single trap lure to monitor or mass trap populations of co‐occurring elaterids is of interest to farmers. This strategy has been tested in integrated pest management programmes for other insect taxa, such as cerambycid beetles (Fan et al, 2019; Hanks et al, 2018; Rice et al, 2020; Sweeney et al, 2014), moths (Brockerhoff et al, 2013; Knight et al, 2014; Preti et al, 2020), true bugs (Kim et al, 2015; Yasuda et al, 2010) and mealybugs (Sullivan et al, 2023; Waterworth et al, 2011). As a key feature of such a lure, the pheromone for each species must express the same level of attractiveness as it would in a single pheromone lure.…”

A trap baited with multiple pheromones attracts sympatric hemipteran pests of sweet persimmon

“…Traps with the multiple species pheromones were as effective as traps with a single pheromone for each pest. It is reported that the mixed and the combined lures could be useful as simultaneous monitoring tools for two sympatric major rice pests using a single trap (Yasuda et al, 2010). Brockerhoff et al (2013) stated that multiple-species trapping with a single trap has several advantages compared with single species trapping with single traps; requirement of fewer traps, saving labor and time to install traps and to check trap catches, reduction of diagnostic effort, and ultimately reduction of costs.…”
