“…3 , but later described as a new species of Wollastoniella 27 ) was discovered and evaluated as an effective predator of T. palmi on eggplant 3 . W. rotunda diapause was not induced under relatively low temperature and short-day conditions 15 . Moreover, the developmental threshold in immature stages of W. rotunda (at 11.5°C) was below the average winter temperature (approximately 13°C) in Japanese greenhouses that grow eggplant 17 .…”

“…putrescentiae W. rotunda: Adults and nymphs collected from eggplants infested with T. palmi in Prachin Buri, Kamphaengsaen, and Suphan Buri, Thailand, in 1995 were used to initiate a laboratory colony for our study and other studies 15,17,20,21 . The W. rotunda colony was reared through several generations on potted eggplants infested with T. palmi in a thermostatic incubator at 25°C ± 1°C and 16L8D without controlled RH.…”

“…These life history traits of W. rotunda are suitable as those of a biological control agent against T. palmi on vegetables in Japanese greenhouses during winter. In fact, the results from cage trials of W. rotunda showed that this predator successfully developed, reproduced, and suppressed T. palmi populations on eggplant in winter greenhouses 15 . The release of W. rotunda against T. palmi populations on eggplant in greenhouses during two winters proved successful in controlling pest populations 22 .…”

Suitable Food of W. rotunda grown in greenhouses. However, the use of O. strigicollis as a control agent against thrips is difficult because the reproduction of this predator is reduced under the low temperature and short-day conditions in winter, even when released in heated greenhouses 19. Therefore, nondiapausing natural enemies from tropical or subtropical regions should be used to extend the biological control of T. palmi to greenhouses in Japan during winter. The possibility of such use had already been suggested 4,11,14 when the use of O. strigicollis as a biological control agent against T. palmi in Japanese greenhouses was initiated.

“…The anthocorid, W. parvicuneis Yasunaga also preys on T. palmi in eggplant crops in northern Thailand (Yasunaga 1995). Cage trials in Japan in winter glasshouses showed that W. rotunda successfully developed, reproduced and suppressed T. palmi populations (Nakashima et al 2004). These authors concluded that this species has the potential to be an effective control for T. palmi on eggplant.…”

Thrips palmi is a major pest of many crops in the tropics and sub-tropics, and is a serious threat within the protected horticulture industry in other parts of the world including the UK. Widespread use of insecticides against T. palmi throughout the world coupled with the restricted range of products available makes it essential to find alternative systems for control. The scattered information on its natural enemies, particularly predators and parasitoids, is reviewed and their potential for use in the control of T. palmi as part of IPM strategies in the UK is considered. Natural enemies selected for detailed examination include: Amblyseius spp., Anthocoris nemoralis , Atheta coriaria , Bilia spp., Campylomma spp., Ceranisus spp., Deraeocoris spp., Franklinothrips spp., Hypoaspis spp., Orius spp. and Phytoseius spp. Recommendations for further investigations are made, including screening and efficacy testing of candidate predators and parasitoids, using semiochemicals to enhance their effectiveness, and assessing the compatibility of chosen species with other components of an IPM system.

Neotropical Entomology 37(5): 582-590 (2008) Plano de Amostragem para Tripes (Thysanoptera: Thripidae) em Pepino RESUMO -Este trabalho determina a melhor técnica, unidade amostral e o número de amostras para compor um plano de amostragem para os tripes Frankliniella schultzei (Trybom) e Thrips palmi (Karny) em pepino. A efi cácia de três técnicas de amostragem: batida de folhas em bandeja plástica branca, contagem direta de insetos na face inferior das folhas e coleta de folhas em sacola plástica foi comparada em nove cultivos comerciais de pepino, empregando três unidades amostrais (uma folha de ramo localizado nos terços apical, mediano e basal do dossel da planta). Baseado na variância relativa e precisão econômica dos melhores sistemas amostrais (melhores técnicas e unidades amostrais), calculou-se o número de amostras para a composição do plano de amostragem convencional. O sistema mais adequado para a amostragem de F. schultzei em pepino foi a contagem direta de insetos em folha do terço apical do espaldeiramento. Para tanto, deve-se amostrar uma folha por planta em 38 plantas/lavoura. Para a amostragem de T. palmi, o melhor sistema foi a batida de folha do terço apical do espaldeiramento em bandeja plástica. Na amostragem conjunta das duas espécies, o sistema mais adequado foi a contagem direta dos insetos em folha do terço apical do espaldeiramento. Nesse caso, amostra-se uma folha por planta, em 35 plantas/ lavoura. Estes resultados facilitam a tomada de decisão no manejo de tripes em pepino, agregando os benefícios da decisão correta para adoção ou não de práticas de redução populacional. PALAVRAS-CHAVE: Cucumis sativus, Frankliniella schultzei, Thrips palmi, tomada de decisão, distribuição binomial negativaABSTRACT -This work determines the best technique, sampling unit and the number of samples to compose a sampling plan for Frankliniella schultzei (Trybom) and Thrips palmi (Karny) (Thysanoptera: Thripidae) on cucumber. The effi cacy of three sampling techniques: leaf beating on a plastic tray, direct counting of insects on the lower leaf surface, and whole leaf collection in bags were compared in nine commercial cucumber crops using three sampling units (a leaf from a branch located in the apical, median or basal third of the canopy). The number of samples was determined based on the relative variance and the economic precision for the best technique and sampling unit. The direct counting of insects on the apical third of the plant canopy was the best sampling technique for F. schultzei based on one leaf surveyed per plant using 38 plants per fi eld. The best sampling technique for T. palmi was the leaf beating on a tray using one leaf of the apical third per plant and 35 plants per fi eld. When joining both species, the best sampling system was the direct counting on the apical third, and it requires sampling one leaf per plant using at least 35 plants per fi eld. These results facilitate the decision-making for the management of thrips on cucumber and aggregate the benefi ts of the correct deci...
