AbstractThree species of ambrosia beetles (Trypodendron lineatum (Olivier), Gnathotrichus sulcatus (LeConte), and G. retusus (LeConte) (Coleoptera: Curculionidae: Scolytinae)) have been estimated to cause annual losses of $95–$189 million in degrade of logs and lumber on the British Columbia coast, in Canada. A consultant-run semiochemical-based integrated pest management programme was implemented in 1982 against these beetles, following fulfilment of four prerequisites: (1) presence of receptive potential clients, (2) availability of semiochemical lures, (3) invention of an operational trap, and (4) proof of concept of mass trapping technology. The programme is based on two broad strategies: maintain the problem at a tolerable level and, if necessary, reduce the problem to a tolerable level. One measure of effectiveness over 12 years of mass trapping at a dryland sort near Sooke, on Vancouver Island, British Columbia, was 16.4 million beetles trapped and an estimated five to one benefit-to-cost ratio. Despite success, several factors have conspired to reduce the programme from 50 sites serviced in early years to 7 in 2018. Timber companies in British Columbia are currently showing renewed interest and are taking steps to incorporate the integrated pest management programme as a formal component of their overall operations.

Aim: Some genotypes of mothbean were screened for their comparative preference against jassids, whiteflies and thrips. Materials and Methods: The experiment was laid out during Kharif season in Randomized Block Design with three Replications. Ten genotypes (viz., RMO-225, RMO-40, RMO-423, RMO-435, RMO-257, RMO-25, RMO-141, RMO-20-36, RMO-04-01-28 and RMO-28-80) were screened against major sucking insect pests which were replicated thrice. Observations: The observations were recorded after two weeks of sowing at weekly intervals after two weeks of sowing. The pest populations were recorded on five randomly selected and tagged plants per plot in early hours when insect have minimum activity. Results: The data revealed that none of the genotypes ware found free from sucking insect pest attack. On the basis of peak population, the genotypes RMO-25 and RMO-141 were categorized as least preferred to jassids, whiteflies and thrips, whereas, RMO-435, RMO-225 and RMO-04-01-28 as highly preferred to jassids and whiteflies and RMO-435, RMO-225 and RMO-257 as highly resistant to thrips. Conclusion: It is well known that certain genotypes of crops are less attacked by a specific insect-pest than others because of natural resistance. In the integrated pest management programme, growing of varieties (RMO-25 and RMO-141) with less preference to sucking insect-pests is one of the most important tools without additional cost.
