Abstract (in English)
Plum fruit moth Grapholita funebrana Tr. It has names such as plum worm, red plum worm, which has many hosts including peaches, apricots, apples and walnut. It exists in most regions of our country and is considered one of the important pests of plum trees, especially in Kohdaman area. Also, this pest exists in most countries of the world, including Asian, European, American and British countries, and it causes serious damage to plum fruit. The larvae of this pest, like the apple core-eating worm, get inside the fruit and feed on its flesh. Decayed fruits soon rot and become inedible. This moth is active at sunset and spends the whole day motionless on the crown of trees, and the moth activity starts before sunset and nightfall and feeds. The use of optical traps, field inspection, as well as many methods to control the pest population are used as basic tools for successful control of the IPM program. In IPM programs, chemical pesticides are applied only after the presence of the pest in the same area is detected by the monitoring system, and the number of pests exceeds the economic threshold, and non-chemical methods are still unable to control the pest.
