(Z)-10-Hexadecenal (Z10-16:Ald), a key component of lepidopteran sex pheromones, is primarily isolated from the sex glands of female yellow peach moths (Conogethes punctiferalis). Its optimal blend with the (E)-isomer (Z/E ratio of 1:9 at 100 μg/dose) achieves high male capture efficiency (up to 186 moths/lure), enabling effective population monitoring in chestnut orchards and summer corn fields in China.
