Abstract
Weevil species Larinus spp. produce trehala on medicinal plants family of Asteraceae. In this investigation, the biology of weevil Larinus trehalanus G & Sh, was studied as a new species, on the medicinal plant Cousinia stocksii (Asteraceae)in Kerman region under field conditions during 2011 and 2012. The weevil is a univoltine insect, which annually overwinters as an adult. The female insects put their eggs individually on the host's stems, and cover then with their extinctions to protect the dry and natural enemies. The newly hatched larvaefrom eggs penetrate into the host plant stem by digging holes and start feeding on the plant sap. The larvae build trehala on host plant stem. They grow individually inside the trehala capsule. Only one larva grows inside each trehala capsule. In natural conditions, the development of L. trehalanus from egg to emerging adult takes 45.8±0.7 to 46.5±0.5 days. A new generation of adults spent some time on the host plant and then search for a protected site to pass the autumn and winter.
