Cold tolerance of Bactrocera dorsalis
Experiments were carried out in Japan to determine if immature stages of Bactrocera dorsalis (EPPO A1 pest) can aquire a cold tolerance. Immature stages of the oriental fruit fly infesting an artificial diet and orange fruits were subjected to a cold treatment of 1øñ 0.5ø C. It was found that larvae and eggs showed different responses to low temperature and, depending on the length of the transition period until the temperature reached its minimum, can aquire a cold tolerance.
