“…Morphological and electrophysiological studies of comparable sensilla in C. fumiferana have demonstrated their bimodal contact chemo‐mechanosensory function (Städler & Seabrook, 1975; Walters et al., 1998). The role of a moth's proboscis in detecting allelochemicals during oviposition has been suggested by ablation experiments in C. fumiferana (Rivet & Albert, 1990) . However, such experiments have not been carried out in L. botrana , and further observations are necessary in order to confirm whether this organ contacts the plant surface during oviposition.…”

We describe the number, distribution, and function of sensilla located on different organs of Lobesia botrana (Lepidoptera: Tortricidae) females using scanning electron microscopy, selective staining, and contact electrophysiology. The tarsi of the prothoracic legs bear contact chemo-mechanoreceptor sensilla chaetica (5 -13 per tarsomere), arranged in rings mainly concentrated on ventral surfaces, and different mechanosensory structures (sensilla chaetica, sensilla squamiformia, sensilla campaniformia, and spines). A single contact chemo-mechanoreceptor sensillum chaeticum is present between the claws on the pretarsus. The ventral surface of the ovipositor lobes is covered with numerous mechanosensory sensilla chaetica of different types, out of which 10 have a contact chemosensory function. Putative contact chemo-mechanoreceptor sensilla were also observed on the proboscis and antenna. Longitudinal rows of alternated sensilla styloconica and basiconica are present on the distal part of the proboscis, and rings of sensilla chaetica are present at the antennal tip. The sensilla on these body parts may play different roles in the selection of an oviposition site.

“…Clearly, a variety of different cues modulate these activities (McNeil et al 1995;Delisle and Hardy 1997), but contact chemoreception plays an important role in egg-laying behaviour. Rivet and Albert (1990) and Grant et al (2000) provided evidence that compounds stimulating oviposition are present on the surface waxes of host needles. Thus, the detection of specific chemicals reflecting plant quality could be important for this species, and chemosensilla have been identified on the tarsi (Mitchell and Seabrook 1974) and the proboscis (Städler and Seabrook 1975;Walters et al 1998).…”

Four types of trichoid sensilla were described on the ovipositor of the spruce budworm, Choristoneura fumiferana (Clem.) (Lepidoptera: Tortricidae). Types I and III sensilla were short and long multiporous hairs, respectively. Type IV sensilla were long and aporous. Each was innervated by a single dendrite. Type II sensilla were multiporous and also had a single terminal pore. They were innervated by four dendrites. Electrophysiological responses were obtained from these type II sensilla to a range of chemical stimuli.Résumé : Quatre types de sensilles chétiformes etaient présents sur l'ovipositeur de la tordeuse des bourgeons de l'épinette Choristoneura fumiferana (Clem.) (Lepidoptera : Tortricidae). Les sensilles des types I et III étaient des soies multipores; celles de type I étaient courtes et celles de type III longues. Les sensilles de type IV etaient longues, mais sans pores. Ces trois types de sensilles abritaient tous un seul dendrite. Les sensilles de type II étaient multipores, mais elles avaient aussi un seul pore terminal et elles abritaient quatre dendrites. Avec l'électrophysiologie, nous avons dé-monté que les sensilles de type II réagissaient à divers produits chimiques. Banga et al. 2037

“…Similarly, increased oviposition in the presence of host plant waxes observed in the present experiment is consistent with previous research (Rivet & Albert, ; Wallace et al ., ), but could be due to a variety of wax components, some of which, notably carboxyl acids, have been shown to be stimulatory (Grant et al ., ). We show that monoterpenes per se also have a stimulatory effect on oviposition.…”

“…Similarly, C. fumiferana moths oviposit more on discs treated with host plant waxes (Rivet & Albert, ; Wallace et al ., ) and with hexane host plant extracts (Grant & Langevin, ), suggesting that host cues are generally stimulatory. Prior to oviposition, females drum the surface with the legs and probe with the ovipositor, and these behaviors are thought to involve detecting surface chemicals in order to make a decision about the suitability of the substrate for oviposition (Wallace et al ., ).…”

Spruce budworm feeding and oviposition are stimulated by monoterpenes in white spruce epicuticular waxes

Monoterpenes, source of the distinctive odor of conifers, are generally considered plant defensive compounds. However, they are also known to act as long-range insect attractants, as they are volatile and permeate forest airspaces. Moreover, they are lipid soluble and can be absorbed into plant epicuticular waxes. We test their role in short-range host plant choice by both adult females and larvae of a folivorous forest pest (Choristoneura fumiferana). We conducted laboratory assays testing the responses of Eastern spruce budworm to an artificial monoterpene mix (α-pinene, β-pinene, limonene, myrcene) and to white spruce (Picea glauca) epicuticular waxes in closed arenas. Ovipositing females preferred filter paper discs treated with P. glauca waxes to controls, and preferred the waxes + monoterpenes treatment to waxes alone. However, females showed no preference between the monoterpene-treated disc and the control when presented without waxes. Feeding larvae prefered wax discs to control discs. They also consumed discs treated with realistic monoterpene concentrations and wax preferentially over wax-only discs, but showed no preference between extremely high monoterpene concentrations and wax-only controls. In an insect-free assay, P. glauca epicuticular wax decreased monoterpene volatilization. These results suggest that P. glauca waxes and realistic concentrations of monoterpenes are stimulatory to both egg-laying females and feeding larvae, and that their effects are synergistic.
