Abstract:

This paper reports the distribution, nature and impact of damage, life
history, number of generations in a year, host records and biocontrol agents of
the beehole borer, Zenzera conferta Walker (Cossidae : Lepidoptera) infesting
keora (Sonneratia apetala Buch.-Ham.) plantations along the coastal belt of
Bangladesh. The pest profusely tunnels in the stem rendering the tree to wind
breakage. It probably completes two generations in a year. Besides keora, the
pest attacks Sonneratia caseolaris, Avicennia officinalis, A. alba and Tamanx indica.
Woodpeckers (Dinopium benghalense and Picoides canicapilltis) and a small black
ant were found to feed on the larvae and pupae of the pest.
