Trypodendronlineatum (Olivier) and Gnathotrichussulcatus (LeConte) beetles (Coleoptera: Scolytidae) were marked with fluorescent powder and released in a sawmill area during a pheromone-based mass trapping program for ambrosia beetles. Trapping efficiency was estimated at 5.9% for T. lineatum and 5.5% for G. sulcatus. This technique had good potential for obtaining information on trapping efficiency, population size, and beetle dispersal patterns. Suggestions are given for improving the accuracy of the information obtained and for additional uses of mark-recapture in evaluating and optimizing mass trapping programs for ambrosia beetles.

The algebraic relationships, underlying assumptions, and performance of the recently proposed closed-subpopulation method are compared with those of other commonly used methods for estimating the size of animal populations from mark-recapture records. In its basic format the closed-subpopulation method is similar to the Manly-Parr method and less restrictive than the Jolly-Seber method. Computer simulations indicate that the accuracy and precision of the population estimators generated by the basic closed-subpopulation method are almost comparable to those generated by the Jolly-Seber method, and generally better than those of the minimum-number-alive method. The performance of all these methods depends on the capture probability, the number of previous and subsequent trapping occasions, and whether the population is demographically closed or open. Violation of the assumption of equal catchability causes a negative bias that is more pronounced for the closed-subpopulation and Jolly-Seber estimators than for the minimum-number-alive. The closed-subpopulation method provides a simple and flexible framework for illustrating that the precision and accuracy of population-size estimates can be improved by incorporating evidence, other than mark-recapture data, of the presence of recognisable individuals in the population (from radiotelemetry, mortality records, or sightings, for example) and by exploiting specific characteristics of the population concerned.

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.
