“…tree bark, for example, reßects uniformly little energy at all wavelengths except red, where it rises slightly (Prokopy and Owens 1983). A similar trend has been seen for measurements taken from several types of pine (Strom et al 1999, Campbell andBorden 2005) as well as varieties of black walnut, elm, hickory, and ash (D.W.B., unpublished results). Ongoing studies will examine the spectral properties of bark tissue from several ash species.…”

Retinal sensitivity of Agrilus planipennis Fairmaire (Coleoptera: Buprestidae) was examined with an aim to improve trap efficacy for the beetle. Electroretinogram (ERG) recordings from dark-adapted compound eyes of male and female were measured at different wavelengths across the spectrum ranging from 300 to 700 nm. The spectral sensitivity curves revealed peaks in the UV (340 nm), the violet/purple (420-430 nm), blue (460 nm), and green (540-560 nm) regions of the spectrum. Females were sensitive to red regions of the spectrum (640-670 nm), whereas males were not. A spectrophotometer was used to measure the wavelength and reflectance for ash foliage, purple corrugated plastic traps, as well as the elytra and abdomen of adult A. planipennis. Traps were painted using colors based on ERG and spectrophotometer measurements and compared with purple corrugated plastic traps currently used by the USDA-APHIS-PPQ-EAB National Survey. In a field assay conducted along the edges of several A. planipennis-infested ash stands, there were no significant differences in trap catch among green, red, or purple treatments. Dark blue traps caught significantly fewer A. planipennis than red, light green, or dark purple traps. In a second assay where purple and green treatments were placed in the mid canopy of ash trees (approximately 13 m in height), trap catch was significantly higher on green treatments. We hypothesize that when placed in the mid-canopy, green traps constitute a foliage-type stimulus that elicits food-seeking and/or host seeking behavior by A. planipennis.

“…Processing time of collected beetles is reduced over earlier trap types, and the funnels collapse for easy storage and transport of the traps (Lindgren 1983). The Lindgren trap provides a dark, vertical silhouette with similar spectral reflectance properties to that of conifer tree hosts (Campbell and Borden 2005), which is an important component of host location for coniferophagous bark beetles (Campbell and Borden 2006). Attraction to aggregation pheromone-baited Lindgren funnel traps was reduced for three different species of bark beetles when the black funnels were replaced with white ones, suggesting that visual and olfactory cues are integrated in the host location process in bark beetles (Campbell and Borden 2006).…”

Abstract-Insects use semiochemicals to mediate important behaviours such as mating, oviposition, and foraging for resources. Chemical ecology research aims to identify these message-bearing chemicals and develop synthetic copies of semiochemicals for use in integrated pest management (IPM). There has been, and continues to be, an extensive research effort to understand the chemical ecology of various insects considered to be pests of forests in Canada. Canadian chemical ecology research has had an impact on IPM of forest insect pests in Canada and around the world. Canadian researchers have been involved in the identification of semiochemicals used by forest insects and the development and implementation of semiochemical-based management tactics for forest pest management. Semiochemicals have been incorporated into forest pest management for a variety of insect taxa primarily as tools to monitor and control forest insect pests in Canada. The goals of the current review are to: (1) highlight research conducted on semiochemical-based management of forest pests in Canada; (2) discuss the current and potential uses of semiochemicals in IPM of forest pests in Canada; and (3) evaluate potential areas for increased research and implementation of semiochemicals into the management of forest pests in Canada.

“…Frisch (1966) was first to prove associative learning of colors in the honey bee, by showing how workers that had always been fed on blue paper could subsequently locate that color among various shades of grey. Campbell and Borden (2005) reported implications of the bark reflectance spectra of conifers and angiosperms for host discrimination by coniferophagous bark and timber beetles.…”

In order to understand the visual orientation mechanisms of the male black chafer Holotrichia loochooana loochooana to females, we examined male behavioral response to colored objects (lures) when female sex pheromone was present. In the field, males landed more frequently on darker lures than on lighter ones of the same color. Among lures of different colors but with the same brightness, males preferred landing on black, blue, or red ones to green or grey ones. The reflectance intensities of preferred lures were weaker than those of green and grey in the range of 540-580 nm. This range is considered to affect choice by males. When females perch on the leaf edges of the food plant to adopt a calling posture, the dominant background color is that of the leaves (i.e., green). This means that the landing target forms a silhouette (dark spot) which is prominent against a background of green leaves, providing maximum visual acuity for mating.
