Specifically, we examined effects of season of slash cutting, sunlight intensity (stand density) and log size on pine engraver (Ips pini Say) reproduction in North-central Arizona, USA. Ponderosa pine (Pinus ponderosa Dougl ex.

Ips is a genus of beetles in the family Curculionidae, the true are bark beetles, members of the subfamily s are distributed throughout the Northern Hemisphere. Some are known as introduced species in Australia and Africa. Many species are pests of forest trees, especially pines and spruces. They are known commonly as engraver beetles, ips engraver beetles, and Class: Insecta. MONOTERPENES AND BARK BEETLES Hobson et al.

Abstract. We determined the response of the small southern pine engraver, Ips avulsus (Eichhoff); eastern fivespined ips, Ips grandicollis (Eichhoff); sixspined ips, Ips calligraphus (Germar); and pine engraver, Ips pini (Say) to the pheromones (±)-ipsenol, (±)-ipsdienol, and lanierone in the southeastern United States. Catches of s and I. Cited by: In some parts of the country, the southern pine beetle’s toll is easy to see: whole ridgelines turn bright reddish brown as pine trees die. But the culprit is harder to spot. Ips engraver beetles and turpentine beetles are also common in the South, and they’re also very small and difficult to identify in the field.

Repeatability, a measure of the proportion of variance in a character that occurs among rather than within individuals, is assessed for the phenotypic trait of female response preference for enantiomeric blends of ipsdienol inIps pini at two pheromone concentrations—1 µg and 5 μg of ipsdienol.

Introduction. Pine bark beetles are frequent pests of stressed pines, Pinus spp., in the southern United States. The five most common southern pine bark beetle species include three in the genus Ips: the sixspined ips, Ips calligraphus (Germar); the eastern fivespined ips, Ips grandicollis (Eichhoff); and the small southern pine engraver, Ips avulsus (Eichhoff); and two species of Dendroctonus.
The most damaging bark beetle species attacking Minnesota's pines are native engraver beetles (Ips species), also known as pine bark (Norway) and jack pine are the most common victims of pine bark beetles, although white pine and spruce can also be infested.We determined the response of the small southern pine engraver, Ips avulsus (Eichhoff); eastern fivespined ips, Ips grandicollis (Eichhoff); sixspined ips, Ips calligraphus (Germar); and pine engraver, Ips pini (Say) to the pheromones (+/-)-ipsenol, (+/-)-ipsdienol, and Cited by: Within-season responses of Pinusresinosa and Pinusbanksiana to fungi vectored by the pine engraver, Ipspini, are strongly influenced by the month of seasonal pattern is a characteristic of the host-fungus interaction, rather than being indicative of either host-or fungal-specific properties by:
