First record and biology of coffee bean weevil (Araecerus fasciculatus De Geer) on pesticide plant (Melia azedarach L.) from Iran

摘要

Araecerus fasciculatus was recorded for the first time in Iran on the seeds of medicinal and pesticide plant, Melia azedarach L. About 25% of the mature seeds were found infected by this pest. Biological studies carried out on the collected specimensduring showed that females lay eggs on the immature, mature as well as dried harvested seeds. Larval nutrition, development and pupation occurred within the seeds. All motile stages of the pest developed throughout the year in the dried seeds. Adult maleand female emerged through chewing of exit holes of the infected seeds. l/lultiple and overlapping generations of larvae, pupae, and adults were also visible in the infected seeds. The pest completed its life cycle within 43 day under the laboratory conditions.
