A biological trapping agent based on the sex pheromone of the tent caterpillar and a preparation method thereof
By using a specific tetradecenol/acetate series compound complex and a polymer slow-release carrier to simulate the sex pheromone of the female tent caterpillar moth, the problem of poor attraction effect of existing dodecadiene compounds was solved, and a highly efficient and long-lasting biological control effect was achieved.

AI Technical Summary
The existing sex pheromone components of tent caterpillars are mainly concentrated in dodecadiene compounds, which cannot completely cover the pheromone components actually released by female moths, resulting in poor attraction effects. New components need to be explored to improve field trapping efficiency.
A specific tetradecenol/acetate series of compounds ((Z)-5-tetradecenol acetate, (Z)-5-tetradecenol and (Z)-7-tetradecenol acetate) were combined with antioxidants and light stabilizers and loaded onto a polymer slow-release carrier to form a biological trap that simulates the real component spectrum of female moth sex pheromones.
It significantly increased the number of male tent caterpillars captured and the mating inhibition rate. The average daily capture rate of a single trap reached 35-40 caterpillars/day, the mating inhibition rate reached over 78%, and the effective period lasted for 60-90 days, meeting the requirements of green plant protection.
