“…Such variation in interest alignment and conflict are more likely to occur: when vertical transmission is costly, horizontal transmission takes place, within-host competition varies depending on single versus multiple infections, and there are (negative) effects of excessively intensive exploitation of the host (Van Baalen & Sabelis 1995;Genkai-Kato & Yamamura 1999;Van Baalen & Jansen 2001). Clearly, thrips do not transmit the gut bacteria transovarially, nor externally via the egg (De Vries et al 2001b). However, this does not necessarily imply a loss of control of the host.…”

“…Western flower thrips is a small, plant-feeding insect that has symbiotic bacteria in its hindgut (Ullman et al 1989;De Vries et al 1995). Thrips have a permanent association with bacteria from the genus Erwinia; the particular strain used in this study was labelled TAC (Thrips-Amsterdam-Chrysanthemum).…”

“…To our knowledge, there is no evidence for transovarial vertical transmission or any external route of egg contam-ination with bacteria (De Vries et al 2001b). Instead, each generation of larvae of the thrips acquires the gut bacteria anew by feeding preferentially on leaves that have been fed upon by other conspecific thrips.…”

“…Such thrips can be compared with a symbiotic control group reared in the same way except that the leaf discs were grazed by other thrips larvae during 24 h prior to the actual experiment. The latter treatment has been proved to lead to reliable horizontal transmission of bacteria (De Vries et al 2001b). …”

“…Instead, each generation of larvae of the thrips acquires the gut bacteria anew by feeding preferentially on leaves that have been fed upon by other conspecific thrips. One type of Erwinia bacteria quickly outcompetes all other gut bacterial types (De Vries et al 2001b). Whether this mode of transmission is closer to being vertical or horizontal now depends on the spatial pattern of relatedness in thrips (meta-) populations.…”

Studies on bacteria in the gut of insect species are numerous, but their focus is hardly ever on the impact on host performance. We showed earlier that Erwinia bacteria occur in the gut of western flower thrips, most probably acquired during feeding. Here, we investigate whether thrips gain a net benefit or pay a net cost because of these gut bacteria. On a diet of cucumber leaves, the time to maturity is shorter and the oviposition rate is higher in thrips with bacteria than in thrips without (aposymbionts). When fed on cucumber leaves and pollen, aposymbionts develop faster and lay more eggs. So Erwinia bacteria benefit or parasitize their thrips hosts depending on the diet, which is in accordance with theoretical predictions for fitness of organisms engaged in symbiotic interactions. Possibly, the transmission of gut bacteria has not become strictly vertical because of this diet-dependent fitness variability.

Insight into animal biology and development provided by classical genetic analysis of the model organism Drosophila melanogaster was an incentive to develop advanced genetic tools for this insect. But genetic systems for the over one million other known insect species are largely undeveloped. With increasing information about insect genomes resulting from next generation sequencing, RNA interference is now the method of choice for reverse genetics, although it is constrained by the means of delivery of interfering RNA. A recent advance to ensure sustained delivery with minimal experimental intervention or trauma to the insect is to exploit commensal bacteria for symbiont-mediated RNA interference. This technology not only offers an efficient means for RNA interference in insects in laboratory conditions, but also has potential for use in the control of human disease vectors, agricultural pests and pathogens of beneficial insects.
