Abstract
Yellow sticky traps (YSTs) are a standard tool for insect monitoring in greenhouses. These traps have been further developed by using them in combination with green light-emitting diodes (LEDs) to increase their attractiveness towards pest insects such as aphids and whiteflies. However, also natural enemies, such as the whitefly parasitoid Encarsia formosa Gahan (Hymenoptera: Aphelinidae), are attracted to these traps. This may cause problems with biological control of the pest or may be used for indirect monitoring purposes. Therefore, we compared the attractiveness of YSTs and green (521 nm) LED traps towards E. formosa under practical growing conditions in tomato, Solanum lycopersicum L. (Solanaceae) and cucumber, Cucumis sativus L. (Cucurbitaceae), crops in the greenhouse. The aim of the study was to investigate the compatibility of LED traps with this parasitoid frequently used against the greenhouse whitefly, Trialeurodes vaporariorum Westwood (Hemiptera: Aleyrodidae). The results show LED traps catching less E. formosa than standard YSTs. Moreover, LED traps also showed compatibility with other beneficial insects. The results are discussed in the context of the parasitoid's behaviour towards various green light spectra and in the context of pest and beneficial insect monitoring using different trap types. Our study will help implementing green LED traps in future insect monitoring programmes and developing new pest control strategies without affecting natural enemies.
期刊介绍：
Entomologia Experimentalis et Applicata publishes top quality original research papers in the fields of experimental biology and ecology of insects and other terrestrial arthropods, with both pure and applied scopes. Mini-reviews, technical notes and media reviews are also published. Although the scope of the journal covers the entire scientific field of entomology, it has established itself as the preferred medium for the communication of results in the areas of the physiological, ecological, and morphological inter-relations between phytophagous arthropods and their food plants, their parasitoids, predators, and pathogens. Examples of specific areas that are covered frequently are:
host-plant selection mechanisms
chemical and sensory ecology and infochemicals
parasitoid-host interactions
behavioural ecology
biosystematics
(co-)evolution
migration and dispersal
population modelling
sampling strategies
developmental and behavioural responses to photoperiod and temperature
nutrition
natural and transgenic plant resistance.
