[G-04] Behavioral response ultrasonic irradiation in simulated flight and oviposition of cabbage looper moth
The evaluation of the effect of ultrasonic irradiation on the simulated flight and oviposition of Trichoplusia ni, also known as the cabbage looper, represents a pioneering effort in the realm of IPM. Ultrasonic irradiation, as an innovative tool in physical pest control, holds considerable promise due to its selectivity, environmental friendliness, and departure from traditional chemical insecticides. Most noctuid moths, including T. ni, possess a tympanal organ, a vital component adversely affected by ultrasonic waves. The Japanese house bat, Pipistrellus abramus, emitting downward frequency-modulated (FM) pulses with a low duty cycle (LDC) and short duration was investigated. T. ni, exhibited greater aversion to shorter duration pulses, as evidenced by flight suppression percentages consistently low for both sexes as well as in oviposition observation. These findings underscore the crucial role of pulse duration in shaping T. ni, 's repellent behavior, offering valuable insights for refining ultrasonic applications in Cruciferous crops.
