the tomato leafminer, tuta absoluta (meyrick), is one of the most important pests of tomato, solanum lycopersicum l., in iran. in this research, natural enemies diversity of t. absoluta and proportion of predators or parasitoids density to moth eggs or larvae density on five tomato cultivars including super strain b, super chief, mobil, korral, and early urbana y were studied in an experimental...

This study examined the effects of various levels of nitrogen inputs (optimal, insufficient and excessive) and water inputs (optimal, low drought and high drought) to tomato plants (Solanum lycopersicum) on survival and development of an invasive tomato leafminer, Tuta absoluta (Meytick) (Lepidoptera: Gelechiidae). Plant growth i.e. plant height and the number of nodes declined under insufficie...

The tomato leafminer Tuta absoluta is native to South America where its preferred host crop is the tomato. Tuta absoluta was detected in Europe for the first time in Spain in 2006. Since then, it has rapidly invaded other European countries and spread throughout the Mediterranean basin, including North Africa and the Middle East [1]. The pest found a perfect environment in the Mediterranean reg...

Abstract Background Effects of entomopathogenic fungi (EPF); Beauveria bassiana , Isaria fumosorosea and Pupureocillium lilacinum against tomato leafminer, Tuta absoluta (Meyrick) (Lepidoptera: Gelechiidae), which is one the most economic pests tomato, were investigated in Petri dish, pot greenhouse experiments. Commercial bioinsecticide Met 52 was also used In dish trials, I. applied to third ...

Tomato leafminer, Tuta absoluta (Meyrick), (Lepidoptera: Gelechiidae), poses severe threats to sustainable tomato production globally with a high capacity develop resistance pesticides. Recently, the management programs for this cosmopolitan pest have relied on combinations of chemical insecticides which exacerbate problems cross-resistance and adverse environmental effects. A novel concept int...

Leafminer (Liriomyza langei Frick) is a major pest that causes considerable damage to a wide variety of vegetable crops including lettuce, and resistant cultivars remain the most economic means of insect control. Eighty-four lettuce cultivars and introduction lines were grown in an insect cage with eight replications for resistance screening. Leafminer flies were released in the cage to feed on...

Laboratory studies was conducted to investigate effect of mating behavior on egg laying, host selection and competition with Bracon hebetor. The results showed that no differences in laying between mated unmated females. number were 90.67 per female females respectively. However produce only males progeny.The parasitoid response the larvae different lepidopterous insects such as. Mediterranean ...

The tomato leafminer, Tuta absoluta (Lepidoptera: Gelechiidae), is a devastating pest that develops principally on solanaceous plants throughout South and Central America and Europe. In this study, we tested the influence of three levels of T. absoluta infestations on the attraction and oviposition preference of adult T. absoluta. Three infestation levels (i.e., non-infested plants, plants infe...

The tomato leafminer Tuta absoluta Meyrick is a key insect pest of tomato in Tunisia and in many other countries around the world. The present study was carried out to attempt to acquire better knowledge of the biology of this insect and to implement suitable prophylactic control tools for T. absoluta in Northeastern Tunisia. Under greenhouse conditions, T. absoluta females exhibited a stronger...
