Field trials of synthetic sex attractants of Illiberis pruni in China

Abstract

The objective of this work was to determine the best conditions for the use of synthetic sex attractants to monitor Illiberis pruni Dyar (Lepidoptera: Zygaenidae, Procridinae) in the Helan Mountain National Nature Reserve, Ningxia, China. Traps with binary blends of 2-butyl (7Z)-dodecanoate (300 µg) and 2-butyl (9Z)-tetradecanoate (300 µg) at a ratio of 1:1 caught the most moths. Catches were significantly different across 5-45 m inter-trap distances; the optimal trapping radius was 25 m. Trap height did not affect catches. The slope aspect, temperature, and humidity significantly influenced catches. More moths were caught as temperatures increased and relative humidity decreased. Traps placed on shady slopes caught significantly more moths than did traps placed on sunny slopes. This study elucidates how various factors influence the effectiveness of traps. The implications of these findings could facilitate safer and more environmentally friendly in situ management of I. pruni.

Sex pheromone of the fall armyworm, Spodoptera frugiperda: identification of a trace component that enhances attractiveness and specificity

“…Therefore, for development of an efficient management tactic against this pest, it is critical not only to forecast the timing of immigration, but also to monitor local occurrence by capturing moths. Pheromone‐baited traps are generally species‐specific, easy to handle, and cost‐effective, and they are frequently used for monitoring of insects (e.g., Parker et al, 2020; Wenninger & Eigenbrode, 2020; Liu et al, 2021).…”
