“…In Yunnan, in southwestern China, where three Tomicus species can coexist in the same P. yunnanensis forest, it was not known how these three Tomicus species would interact. That is, would they compete with each other for the same resource or would they reduce competition by partitioning their breeding resource either spatially or seasonally (Paine et al 1981, Flamm et al 1987, Wilkinson and Haack 1987, Haack et al 1989, Amezaga and Rodríguez 1998, Ayres et al 2001? Obviously, answering this question will help in understanding the damage potential caused by the various Tomicus species in southwestern China.…”

“…The presence of more than one species of bark beetle attacking a single weakened tree may have positive and negative effects on beetle populations such as a combined effect that helps the beetles to overcome tree resistance or to increase competitive interactions among the beetle species (Light et al 1983;Wagner et al 1985;Flamm et al 1987;Rankin and Borden 1991;Schlyter and Anderbrant 1993). Although many studies have addressed the effects of biotic interactions on the populations of species from different taxonomic groups (e.g.…”

Ecological segregation of bark beetle (Coleoptera, Curculionidae, Scolytinae) infested Scots pine

Bark beetles infest several pine tree species, often creating major economic losses. Biotic interactions between Scolytinae populations inhabiting Pinus sylvestris were analyzed using a new sampling method involving a two dimensional division of tree space resources into units and sections. The goal was to evaluate the effects of the type of available reproduction material on insect infestation. The P. sylvestris stands in this study included an analysis of bark beetles colonizing dead trees and uninfested living trees (trap trees). Analyzed trees were harvested and their stems divided into ten equal units; each unit was halved into two sections (half of the stem circumference). The colonization of dead trees by insects was evaluated immediately after cutting for infested trees and 2 months after cutting for trap trees. The type of breeding material significantly affected the species composition of bark beetles infesting P. sylvestris. The dead trees were colonized mostly by Trypodendron lineatum and Tomicus minor, and to a lesser extent by Tomicus piniperda, which dominated in trap trees. Tomicus piniperda and T. lineatum preferred thicker stems; however, T. minor, Hylurgops palliatus and Pityogenes bidentatus preferred thinner ones. The application of the new sampling method helped to increase the accuracy of niche segregation among insect species. The results of niche segregation indicate bark beetles exhibited spatial specialization in the use of resources, mainly related to the moisture content of breeding material and the availability of food resources which is the main factor determining the coexistence of bark beetles in the same environment.

“…Despite the importance of Ips beetle attacks on live trees ( Wood, 1982;Flamm et al , 1987;Eidmann, 1992;Wermelinger, 2004 ), few studies have investigated the behaviour of beetles when populations commence attacking live hosts ( Hedgren & Schroeder, 2004 ). More emphasis has been placed on the effects of tree variables such as monoterpene content or phloem thickness and moisture on reproduction and performance of beetles within hosts ( Haack et al , 1984;Villa-Castillo & Wagner, 1996;Reid & Robb, 1999;Hindmarch & Reid, 2001;Redmer et al , 2001 ) than on the preferences of beetles attacking live trees.…”

1 The present study investigated the influence of tree size and bole position on selection of ponderosa pines ( Pinus ponderosa Dougl. ex Laws.) by Ips pini Say (Coleoptera: Curculionidae: Scolytinae) in a northern Arizona forest. Ips pini were attracted to lower and upper bole positions with pheromone lures, and the number of attacks counted. In addition, tree phloem and bark thickness, resin flow in response to wounding and characteristics of tree water and carbon relations were all measured. 2 Bark thickness was the most strongly related tree characteristic to number of I. pini attacks. Thin bark and a high number of attacks occurred at the lower bole position of 10-cm diameter trees and upper bole positions of 23-, 35-, and 50-cm diameter trees. 3 Phloem thickness increased directly with tree size, was greater at the upper bole compared with the lower bole, but was not associated with number of attacks. 4 Resin flow did not differ strongly over tree sizes or bole positions, and was not related to number of I. pini attacks. Attacks were not related to characteristics of tree carbon and water relations measured during I. pini flights.
