Title: Life History and Biology of Ips latidens (LeConte) (Coleoptera: Scolytidae)\t

Description: The life history and biology of Ips latidens (LeConte) were investigated using bark-sandwich and whole-log rearing methods. In contrast with other Ips spp., some females initiated galleries under conditions of female-biased sex ratios, and sometimes 2 or more males were present in a gallery. In general, however, I. latidens exhibited typical ipine characteristics. A single male usually admitted l-3 females into a gallery. Females oviposited at a rate of 2.25 eggs/day and achieved a mean fecundity of 64.4 eggs. The larval stage comprised 80% of the generation time (egg to teneral adult) and analysis of head-capsule widths disclosed 3 larval instars. The mean survivorship within broods was 56.0% after 70 days; the reproductive success of monogamous pairs of beetles was 36.1 teneral adults. Single females constructed 34 egg tunnels/gallery system; hence, harem size cannot always be inferred from the number of egg tunnels in each gallery. The mean generation time in the laboratory was 2.07 x greater than for I. pini. By comparing laboratory data on I. latidens with laboratory and field data on I. pini, the generation time of I. latidens is estimated at 64124 days in the field. In south-central British Columbia, I. latidens probably has 1 generation, and possibly 2 broods, per year.
