Some species routinely attack the trunks and major limbs of their host trees, other bark beetle species mine the twigs of their hosts, pruning and weakening trees and facilitating the attack of other tree pests. While many devastating species of bark beetles are associated with New Mexico conifers, other species favor broadleaf trees and can be equally damaging.

Wood-Boring Insects of Trees and Shrubs
B- 508 6 Wood-boring Insects of Trees and Shrubs Bastiaan M. Drees, Professor and Extension Entomologist John A. Jackman, Professor and Extension Entomologist Michael E. Merchant, Assistant Professor and Extension Urban Entomologist The Texas A&M University System Many insects feed and make their homes in the bark, trunks and branches of shade trees and shrubs in Texas. Bark beetles and insect borers belong to several different insect groups including a variety of beetles, moths and horntail wasps. Most insect borers are attracted to weakened, damaged, dying or dead plants. These are referred to as “secondary invaders” because they attack only after a plant has been weakened by another stress. Secondary invaders are a symptom of other problems with the health of the tree or shrub, but may contribute to its decline. Secondary invaders include species from groups already mentioned, but also may include termites, carpenter bees and carpenter ants. Many other insects live in dying or dead trees, including natural enemies (predators and parasites) of the insect borers, sap or fungi feeders, or species which merely use the spaces provided by the tunnels and galleries as living quarters. Wood-boring insects that attack healthy trees and shrubs are called “primary invaders.” Primary invaders may eventually kill trees. Damage Borer infestations often go unnoticed until plants or parts of plants begin to die or show external signs of damage. Wood-boring insects often produce sawdust-like frass (excrement). Their holes are normally round, oval or semicircular and are found in a random pattern on the plant. Woodpecker damage is sometimes confused with that of wood-boring beetles, however woodpecker damage will not produce frass. -

Wilson2 ABSTRACT.-We examined attributes of pinon pine (Pinus edulis) associated with the probability of infestation by pinon ips (Ips con}usus) in an outbreak in the Coconino National Forest, Arizona. We used data collected from 87 plots, 59 infested and 28 uninfested, and a logistic regression approach to estimate the probability ofinfestation based on plot and tree-level attributes. Pinon pine stand density index was a good predictor ofthe likelihood ofinfestation by pinon ips at the plot level, and a cross-validation analysis confirmed that the model correctly classified 82% ofthe cases. Diam eter at root collar and pifion dwarf mistletoe infestation level were good predictors ofindividual tree infestation, and a cross-validation analysis indicated that the model correctly classified 72% of the cases. Results suggest that the occur rence of pinon ips infestations may be related to stress factors associated with increased stocking and pinon dwarf mistletoe infestations. Key words: Ips confusus, pinon ips, bark beetles, Pinus edulis, pinon pine.

Premessa Negli ultimi anni, complice la globalizzazione dei mercati che ha incrementato gli scambi commerciali in particolare con i Paesi Terzi, è aumentato considerevolmente a livello mondiale e quindi anche nelle regioni italiane il rischio dell'introduzione di nuovi parassiti potenzialmente dannosi dal punto di vista economico per le produzioni ed il patrimonio vegetale ( quarantine pests ) fino ad allora sconosciuti o comunque mai segnalati prima ufficialmente. Tale rischio è particolarmente accentuato in Toscana per la presenza sul territorio sia del distretto vivaistico pistoiese, la più importante realtà vivaistica italiana ed una delle maggiori a livello europeo, sia del porto commerciale di Livorno, tra i principali punti comunitari officiali di importazione di materiale vegetale dall’estero e dai paesi Terzi ( entry point ), attraverso cui transitano ogni anno centinaia di migliaia di tonnellate di prodotti e merce vegetale di diversa natura e provenienza. -
Pinyon Engraver Beetle Acoustics: Stridulation Apparatus, Sound Production and Behavioral Response to Vibroacoustic Treatments in Logs

Bark beetles such as the pinyon engraver beetle Ips confusus use chemical and acoustic cues to communicate and to locate potential mates in trees. In this study, we describe the structures and airborne sounds produced by the pinyon engraver beetle, and test the efficacy of vibroacoustic treatments for tree protection against this beetle. Only female beetles possessed sound producing structures, located on the back of the head and inside the thorax. We analyzed and described the airborne sounds, called chirps, produced by females when held by tweezers or placed on their back. We tested a wide variety of vibroacoustic treatments Citation: Lukic, I.; Bedoya, C.L.; played into logs but these sound treatments did not prevent male entry into logs and did not disrupt Hofstetter, E.M.; Hofstetter, R.W. female–male interactions, female tunneling behavior, reproduction or egg laying.

Ips Beetle Management Prescription 1
COLORADO STATE PARKS STEWARDSHIP PRESCRIPTION Date Created: September 9, 2001 Ips Beetle (Engraver beetle) Revised: April 1, 2005 Author: CSU Cooperative Extension Management Parks Affected: Most parks R A factsheet created by: COLORADO STATE UNIVERSITY COOPERATIVE EXTENSION Graphics and Narrative developed by Curt Swift, Area Extension Horticulturist in collaboration with Peter Barth, Assistant District Forester, CSFS, Montrose, CO & Linda Corwine, CSU Advanced Master Gardener and Horticultural Consultant. Introduction The Ips beetle (aka Engraver Beetle) is a serious pest of pine and spruce with twenty- five species currently recognized in the Western United States. In the Tri River Area of Western Colorado Pinon pine (Pinus edulis) is the favored host of one of these Ips species (Ips confusus). This 5 mm long (3.0 to 6.5 mm) beetle is identified to species by the number and character of the spines located on the back end of the insect. Source: CSFS, 2004. Habits Attracted to stressed trees, invasion by the Ips often results in the production of a pitch tube at the point of entry. This exuding pitch and boring dust is about the length and diameter of your thumb. The center of the tube contains the hole through which the adult beetle enters the inner bark. Vigorous trees attacked by a few adults often produce enough pitch to either drown the beetles in the inner bark or push them back out of their entrance tunnels. Many trees, however, may be attacked by several hundred or thousands of Ips beetles at the same time, overcoming the vigor of the tree. During hot weather the pitch tubes soften and run down the side of the infested tree. -

E-mail: [email protected] Abstract The presence and distribution of two species of Notanisus Walker (Hymenoptera: Pteromalidae) in North America is re- ported. Notanisus sexramosus (Erdős), originally described from Hungary and previously reported from Maryland, USA, is recorded also from Massachusetts and Pennsylvania based on a male and macropterous and brachypterous females. Males of Notanisus are shown to have two types of flagellar structure, ramose and pedicellate, and diagnostic features are given for the previously unknown males of N. clavatus Bouček to differentiate these from those of N. sexramosus and N. versicolor Walker. Five other species are newly described, Notanisus kansensis n. sp. based on a female from Nebraska, USA, and four species from Sub-Saharan Africa and the Arabian Peninsula—Notanisus brevipetiolus n. sp. based on two females from Uganda and Zambia, Notanisus longipetiolus n. sp. based on a female from Zimbabwe and a female and two males from Mozambique, Notanisus vanharteni n. sp. based on a female and several males from United Arab Emir- ates, and Notanisus yemenensis n. -
