Abstract:

Ovipositional preferrence of Bactrocera dorsalis(Hendel) to Psidium guajava L. fruits with different hardness was studied in order to confirm the best bagging time of fruit. The results showed that with the fruit hardness decreasing, the ovipositional preferrence became stronger. The egg quantity on the fruits with different hardness was significantly different. When the fruit hardness was higher than 11 kg·cm-2, the egg quantity on the fruit was zero, so it is the best bagging time of fruit.
