“…against microorganisms. In a variety of arthropods, silk is used as a pheromone source for group living and mating (Penman and Cone, 1974;Roessingh, 1990;Evans and Main, 1993;Saito Y, in press). Indeed, chemical cues from silk are also used by predators and parasites for the recognition of their hosts (Bekkaoui and Thibout, 1993;Weseloh, 1977).…”

“…Silk of T. urticae has been reported to play four main roles: (1) protection against biotic agents like mites predators (Helle and Sabelis 1985;Sabelis and Bakker 1992), (2) protection against abiotic agents, such as rain and acaricides (Gerson 1985), (3) sex pheromone substrate (Cone et al 1971;Penman and Cone 1974) and (4) support for locomotion and dispersal (Saito 1977(Saito , 1979Yano 2008;Clotuche et al 2011). Although substantial work has been done on the role of silk in the biology of T. urticae (Cone et al 1971;Davis 1952;Hazan et al 1975;Helle and Sabelis 1985;Hoy and Smilanick 1981;Linke 1953;Cone 1972, 1974;Sabelis and Bakker 1992;Saito 1977Saito , 1979Yano 2008), the silk itself remains poorly studied.…”

The silk road of Tetranychus urticae: is it a single or a double lane?

et al. 2012

Tetranychus urticae (Acari: Tetranychidae) is a phytophagous mite that forms huge colonies. All active members of a colony (immatures and matures, females and males) spin silken threads. These mites construct a common web that protects the colony from external aggression. The silk coverage is well-known to provide advantages to the colony but very little is known about the characteristics of the threads themselves. Here is the first quantification of the diameter of silken threads spun by two different stages (adult females and larvae) and its relationship with body size of the spinning individuals. Moreover, we observed how silk was deposited on the substrate through their two pedipalps. Threads were observed by means of transmission electron and fluorescence microscopy. Silken threads spun by larvae (0.055 ± 0.018 μm) were significantly thinner than threads spun by adult females (0.111 ± 0.038 μm). In the first step of the silk depositing behaviour, the mite attached the thread to the substrate by putting its pedipalps in contact with the surface (adhesion, double silken threads). When walking, silken threads became detached from the substrate and spitted up (silken threads were free). Finally, silken threads adhered to the surface. The presence of single and double threads makes thread diameter highly variable.

“…The chemicals present in spider mite webbing may have a role during spider mite mating. Indeed, Penman and Cone (1974) showed that the presence of webbing produced by a female prior to quiescence increased male attraction. The webbing is also used by spider mites to locate conspecifics, and larvae are more responsive to the presence of conspecific webbing than adults (Clotuche et al 2013).…”

The Search Behavior of Omnivorous Thrips Larvae is Influenced by Spider Mite Cues

2015

The western flower thrips is an omnivorous insect that consumes both leaf tissue and spider mite eggs. For this reason, these thrips are often described as 'opportunistic predators' of spider mites. Several studies have shown that western flower thrips are often found in association with spider mites, and the development time of thrips decreases and their survivorship increases when they consume spider mite eggs. We tested the hypothesis that thrips larvae may respond to chemical cues from spider mites, and that they may modify their prey-searching behavior when these spider mite-induced cues are present. We prepared hexane extracts from: 1) webbing of spider mites isolated from maize leaves, 2) webbing produced by spider mites inside an empty glass tube to exclude any plant-derived cues from the extract, and 3) spider mite cuticle extracts. These three extracts were subsequently applied in droplets to one-half of filter papers, and hexane alone was applied in droplets to the other half. We showed that residence time of thrips larvae was higher on filter paper with spider mite webbing extract, especially when the extract originated from spider mites isolated in glass tubes. In the presence of webbing extracts, we also observed: 1) a decrease in velocity, 2) an increase of angular velocity and 3) an increase in time immobile. Extracts from spider mite cuticle only increased velocity and proportion of time immobile of the thrips larvae. Our results suggest that chemical cues from spider mite webbing induce an arrestment response and play an important role in the non-random search behavior of thrips larvae searching for eggs on spider mite infested plant leaves.
