“…The function of the gut bacteria for their host has not yet been studied and we test their impact on food conversion in the thrips. Thrips feed primarily on leaf parenchyma, leaf petals and pollen of a large number of species (Kirk 1985;Yudin et al 1986). …”

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.

“…Rutgers mechanically inoculated on fully expanded cotyledons. L. esculentum was selected because it is a crop severely affected by TSWV in Spain; D. stramonium was also selected because it is a wild species shown to support WFT development (Yudin et al, 1986) and reported to be a good host species for TSWV acquisition by WFT (Ullman et al, 1992b;Bautista et al, 1995;Wijkamp et al, 1995). Source plants were inoculated 4-6 weeks before the acquisition assay and were tested for TSWV infection by ELISA.…”

“…Effective control measures to reduce the losses caused by TSWV are not available. Both the virus and its vector have extremely wide host ranges (Yudin et al, 1986;Edwardson & Christie, 1986), and crop management strategies are difficult to implement. TSWV control through control of WFT is difficult because of the high reproductive rate, dispersal capacity, and efficiency of virus transmission by the vector (German et al, 1992).…”

The abilities of different isolates of tomato spotted wilt tospovirus (TSWV) collected from northeastern and eastern Spain to infect 10 host species, and to be acquired and transmitted by the western flower thrips (WFT), Frankliniella occidentalis were compared. Two isolates of TSWV from a single source plant could be separated according to the different type of local lesions they induced in Nicotiana glutinosa. Host ranges of the studied TSWV isolates were very similar, but differences were found in the symptoms induced and in their capacity to infect specific hosts systemically. Lycopersicon esculentum and Datura stramonium were evaluated for their potential as virus acquisition host species. The proportion of transmitter adult thrips obtained from WFT larvae fed on L. esculentum was greater than from D. stramonium. No differences were detected between TSWV isolates in their ability to be acquired and transmitted by WFT. No evidence was obtained of alterations in TSWV particles which could affect WFT transmissibility due to the repeated mechanical transfers used to clone the isolates. Our findings do not support the existence of pathological effects of TSWV on WFT.

“…총채벌레는 일반적으로 식물 표피에서 성충과 약충 단계를 지내면서 식물체를 가해하다가 식물 조직내에 알을 산란하고 토양에서 전용과 용의 단계를 거치는 복잡한 생활사를 갖고 있다. 그러나 이러한 발육시기별 서식장소의 다양성에도 불구 하고 알에서 성충까지의 발육기간이 짧고 채소, 과수, 화훼류 등을 가해하는 광식성 해충으로 기주 식물이 220여종 이상 보 고되었다 (Ananthakrishan, 1993;Yudin et al, 1986). 일반 적으로 총채벌레류는 크기가 성충을 기준으로 1.0~1.5 ㎜ 정 도의 미소곤충이고 주로 식물의 잎이나 꽃 등 연약한 부위나 조직 틈에 서식하는데, 기주식물 재배 초기에 발생시 생장점 부위를 집중적으로 가해하기 때문에 생육초기에는 낮은 밀도 로 발생하더라도 적절한 시기에 예찰하여 방제를 수행하지 않 을 경우 작물의 생육 위축 등 많은 피해를 줄 수 있다 (Cho et al, 2000).…”

: Damages of medicinal crops by thrips and identification of thrips species were investigated by periodic surveys on major medicinal crops, Platycodon grandiflorum, Schizandra chinensis, Codonopsis lanceolata, Lycium chinense, Bupleurum falcatum, Ledebouriella seseloides, Angelica gigas, Glycyrrhiza uralensis, Liriope platyphylla, Atractyloides sp., once or twice a month in Suwon, Eumseong, Jecheon, Pyeongchang, Chyungyang from May to October in 2012. Thrips and their damages were found at all of the medicinal crops investigated, mostly occurring at early growing stages of each medicinal crop and causing apical meristem region withered, thereby inhibiting the growth of plants. For species identification of thrips collected from each medicinal crops, DNA from each individual was extracted and ITS2 and COI regions were amplified by PCR. As a result, Frankliniella intonsa, Thrips tabaci, and Megalurothrips distalis have been identified as dominant species on medicinal crops in open field, whereas Frankliniella occidentalis was restricted to Lycium chinense in which protected cultivation. This study suggests that the occurrence of thrips species on medicinal crops seems to be affected by host specificity and environmental factors such as cultivation types.
