Abstract
BACKGROUND: Long-lasting insecticide-treatednets (LLITNs) constitute anovel alternative that combinesphysical andchemical tactics toprevent insect accessandthe spread of insect-transmitted plant viruses in protected enclosures. This approach is based on a slow-release insecticide-treated net with large hole sizes that allow improved ventilation of greenhouses. The efficacy of a wide range of LLITNs was tested under laboratory conditions against Myzus persicae, Aphis gossypii and Bemisia tabaci. Two netswere selected for field tests under a high insect infestation pressure in the presence of plants infected with Cucumbermosaic virus and Cucurbit aphid-borne yellows virus. Theefficacyof Aphidius colemani, a parasitoid commonly used for biological control of aphids, was studied in parallel field experiments. RESULTS: LLITNs produced high mortality of aphids, although their efficacy decreased over time with sun exposure. Certain nets excludedwhiteflies under laboratory conditions; however, they failed in the field.Nets effectively blocked the invasion of aphids and reduced the incidence of viruses in the field. The parasitoid A. colemani was compatible with LLITNs. CONCLUSION: LLITNs of appropriate mesh size can become a very valuable tool in combination with biocontrol agents for additional protection against insect vectors of plant viruses under IPM programmes.
