The Tomato Leaf Miner, Tuta absoluta (Meyrick) (Lepidoptera Gelechiidae), is actually a most dangerous pest of solanaceous crops.While demonstrating the Tomato Leaf Miner adults, both male and female, ability to feed on tomato leaves we report an unexpected behaviour for this microlepidoptera. This paper details also morphological adaptation of the proboscis involved in feeding and evidences of the action on the leaves.Observation were given by digital camera-equipped stereoscope and Cryo-SEM. We discuss the mean of adult feeding in respect to moth mating and egg laying. A possible use of adult feeding in Tomato Leaf Miner IPM is also discussed.The adult Tomato Leaf Miner is capable to feed by wounding tomato leaf by its proboscis.
Introduction: Aleurocanthus spiniferus (Quaintance) is one further alien invasive pest that have been invading the south of Italy. From the EPPO first report of the presence of A. spiniferus, in April 2008, Puglia was invaded northward by this polyphagous whitefly and new territories were infested more or less severely.Aims: This poster refers about recently occupied areas detailing local and urban outbreaks and population density per host plant species. Materials and Methods: We use direct observation on the field and digital camera-equipped stereoscope and Cryo-SEM on the laboratory for data confirmation and imaging. Results: We detail the invaded areas, confirming the spreading of this pest in almost all the Puglia region. Conclusions: The overall ecological preferences and behaviour of the pest are depicted in view of its control in urban areas.
Tuta absoluta - the tomato leafminer originated from South America was signaled for the first time in the South of Spain in 2006. In Romania Tuta absoluta was detected for the first time in the Western part of the country, into a grange from Satu Mare county in 2009. A year later, in the spring of 2010 its attack was signaled into greenhouses from Curtici, situated in Arad county. We studied the phytosanitary spreading area of Tuta absoluta, into solariums and greenhouses. Observations were made in the greenhouse from west of Romania. The tomatoes crops from greenhouse were verified to establish the frequency of pest attack. There were found insignificant pest attacks of Tuta absoluta in the first months, but in the last weeks we found major attack of this pest in tomato crops. Tuta absoluta is a specie whose area of distributions is expanding. Specialists in the field of plant protection should give special attention to monitoring this invasive pest.
Tuta absoluta species originates from South America. It was signaled for the first time in Europe in 2006 in eastern Spain. In Romania it was detected for the first time in the western part of the country into a grange from Satu Mare county in 2009. After a year the attack of Tuta absoluta was signaled into a greenhouse from Curtici city, Arad county. Studying Tuta absoluta reaction at different chemicals and trying to discover which one is the most suitable and efficient to reduce or eliminate the population of the pest. Observations were conducted in greenhouses in Arad. They used different chemicals to reduce or eliminate the pest Tuta absoluta population. Chemicals had a positive effect to eliminate the pest population of Tuta absoluta. If it is discovered in an early stage of the attack, it can be controlled or eliminate by chemicals treatments.
Introduction: The tomato leaf miner Tuta absoluta (Meyrick, 1917) is a key pest for solanaceous crops, mostly tomato and potato, in many areas of the World. Aims: In this study we present evidences that T. absoluta adults, both males and females, feed on tomato leaves by proboscis. Materials and Methods: Observation were given by a digital camera-equipped stereoscope and confirmed by a Cryo-SEM. Results: We describe and illustrate the adult feeding behaviour and the consequent wounds and scars on the leaves. Discussion and conclusions: A discussion about the role of this unusual behaviour in tomato leafminer biology is given.
