Attraction of Southern Pine Engravers and Associated Bark Beetles (Coleoptera: Scolytidae) to Ipsenol, Ipsdienol, and Lanierone in Southeastern United States

Journal of Economic Entomology, 2005
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 I.

DISTRIBUTION AND ABUNDANCE OF ENGRAVER BEETLES (SCOLYTIDAE: IPS SPECIES) ON MONTEREY PINES INFECTED WITH PITCH CANKER

The Canadian Entomologist, 1990
AbstractPitch canker, caused by Fusarium subglutinans (Wollenw. and Reink.) Nelson, Toussoun, and Marasas, a pine pathogen recently identified in California, may increase the distribution and abundance of Ips spp. on Monterey pines in Santa Cruz Co., CA. In all pine stands, Ips spp. tunneled into healthy branches and boles.

SEASONAL ABUNDANCE OF BENEFICIAL INSECTS AND IPS SPP. ENGRAVER BEETLES (COLEOPTERA: SCOLYTIDAE) IN FELLED LOBLOLLY AND SLASH PINES IN LOUISIANA1

Journal of Entomological Science, 1988
Felled loblolly and slash pine trees were infested with Ips calligraphus (Germar) (80.2% of Ips population), I. avulsus (Eichhoff) (11.2%), and I. grandicollis (Eichhoff) (8.2%). A complex of beneficials associated with the Ips spp. broods consisted of 27 known or suspected insect predator species and 10 species of parasites.

Responses of single receptor cells in the pine engraver beetle,Ips pini (SAY) (Coleoptera: Scolytidae) to its aggregation pheromone, ipsdienol, and the aggregation inhibitor, ipsenol

Journal of Comparative Physiology ? A, 1977
Responses of single olfactory cells on the antennal club ofIps pini have been recorded electrophysiologically. The majority of cells were strongly activated by either/or of the two behavior-modifying chemicals, the aggregation pheromone ipsdienol and the aggregation inhibitor ipsenol.

Frass clearing by male pine engraver beetles (Ips pini; Scolytidae): paternal care or paternity assurance

Behavioral Ecology, 1997
Male parental care and paternity assurance are often associated with long-duration pair bonds. The mating system of the pine engraver beetle, Ips pini, includes an association between the male and female that persists for most of the prolonged opposition period.

Acoustic communication and the role of antennae as putative acoustic sensory organs in pine engraver beetles, Ips pini

2013
Pine engraver beetles, Ips pini Say, 1826 (Coleoptera: Curculionidae), are widely distributed across Canada, and invade several species of Pinus Linnaeus (Pinaceae), where they complete their life cycle under the outer bark, in the phloem. Acoustic communication confers many advantages to insects, and is used in avoiding predation, courtship and mating,
