Abstract: Sap-feeding insects within Hemiptera and Thysanoptera are some of the most important crop pests world-wide. Apart from the loss of yield they cause by sap depletion, saliva toxicity and soiling of the leaves, some species transmit serious plant virus diseases. Important sap-feeding species that have been introduced to the Maltese Islands include the whitefly Bemisia tabaci; the scale insects Pseudo coccus !ongispinus, Planococcus citri and lcerya purchasi; the aphids Aphis gossypii, Aphis spiraecola, Myzus persicae and Viteus viti/oliae; and the thrips Frankliniella occidentalis and Heliothrips haemorrhoidalis. For each of these pests information is provided on area of origin, present distribution, host-plant range and virus disease transmission. Control strategies undertaken in the Maltese Islands are described where relevant. Some general considerations on quarantine measures are discussed. 1999-06-01T00:00:00Z https://www.um.edu.mt/library/oar/handle/123456789/14975 Title: Tenebrionids associated with sandy shores in the Maltese Islands (Coleoptera, Tenebrionidae) Authors: Mifsud, David Abstract: The tenebrionids associated with sand dune beaches in the Maltese Islands are reviewed.

The record of Ocydromus andreae (Fabricius) by Magrini & Schembri is incorrect and should refer to Ocydromus atlanticus (Wollaston). 1999-06-01T00:00:00Z
