We report the first record of Neochrysocharis formosa (Westwood) parasitizing larvae of the tomato moth, Tuta absoluta (Meyrick), in tomato crops in Northern Buenos Aires Province, Argentina. Tomato moth larvae were sampled during four consecutive growing cycles, between 2003 and 2005, in 10 sites. Neochrysocharis formosa was present only in organic outdoor and protected crops, and predominantl...

Tomato leaf miner Tuta absoluta (Meyrick, 1917) (Lepidoptera: Gelechiidae), a devastating pest of tomato originating from South America has been recorded in Serbia on three localities: in tomato main greenhouse and open field production area located in the vicinity of town Leskovac (South Serbia), in surroundings of the village Donji Vrtogoš (near town Vranje, South Serbia) and in a greenhouses...

Macrolophus pygmaeus Rambur (Hemiptera: Miridae) is a generalist predatory mirid widely used in augmentative biological control of various insect pests in greenhouse tomato production in Europe, including the invasive tomato leafminer, Tuta absoluta (Meyrick) (Lepidoptera, Gelechiidae). However, its biocontrol efficacy often relies on the presence of alternative prey. The present study aimed at...

Insect pests are responsible for major losses in crop productivity, and insecticides are the main tools used to control these organisms. There is increasing demand for new products for pest management. Therefore, the aim of this study was to assess the toxicity of pyrethroids with acid moiety modifications to measure the insecticidal activity of these compounds on Tuta absoluta (Meyrick) (Lepid...

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...

The tomato leafminer, Tuta absoluta (Meyrick) is a devastating pest associated with tomato. In this study, effects of tomato plants treated with vermicompost (20, 40, and 60%), humic fertilizer (2, 4 and 6 g/kg soil) and plant growth promoting rhizobacteria (Pseudomonas fluorescens and Bacillus subtilis) were investigated on the life table parameters of T. absoluta in a growth chamber at 25 ± 2...

the objective was to study the population development of tuta absoluta (meyrick, 1917) on tomato in greenhouse conditions at droh. the trial assessed the occurrence of t. absoluta adults from the month of october to may in traps; a low numbers is noted. the high numbers recorded (170 adults/greenhouse) are caught at the end of crop cycle. the mean number of capture is 22 adults/ week/ trap. reg...

Five new pesticides were evaluated for their effectiveness in the control of Tuta absoluta (Meyrick), (Lepidoptera : Gelechiidae) on tomato plant. The effect of pesticides against egg and larvae were estimated after 2, 5 and 7 days from application. The highest reduction percentage of eggs of Tuta absoluta during two successive seasons achieved by Emacit (81.25 and 74.5) % respectively after 7 ...

Our work reports on the establishment of neotropical parasitoid Dolichogenidea gelechiidivoris Marsh (Hymenoptera: Braconidae) for first time in Europe. This larval has been recorded samples collected commercial tomato crops Catalonia (North-eastern Spain) from 2016 to present. is considered be a new biocontrol agent among resident complex Tuta absoluta (Meyrick) (Lepidoptera: Gelechiidae).
