“…Additionally, Zouba and Mahjoubi (2010) reported that the parasitoid Trichogramma is a good weapon to control T. absoluta on greenhouses of south western Tunisia. As well El-Arnaouty et al (2014) showed that both Trichogramma species were significantly efficient, especially at higher doses, in keeping down T. absoluta miners during both experimental years in North African.…”

Tuta absoluta (Meyrick) (Lepidoptera: Gelechiidae) tomato leaf miner is a major pest of the Solanaceae family, this studs was carried out in the open field of three potato varities (Espunta, Mondial and Pliny) at Al-Bustan, Nubaria Western Delta in Egypt in two evergreen (winter and Summer) using pheromone traps as an indicator to infestation by this pest. Also, the parasitoid Trichogramma evanscens (Hymenoptera: Trichogrammatidae) was evaluated to suppressing the infestation as a biological control. Also, the relationship between the adult moth of T. absoluta and temperature o C and relative humidity RH% throw the winter and summer evergreens studied. The result indicated that the population of T. absoluta adult moth in pheromone traps increased in winter evergreen during October and November (19-22°C) and summer evergreen during May and June (23 o-26 o C) in warm climates. The results revealed that Tr. evanscens gave a high significant in reducing the T. absoluta in open field and greatly exacerbates role of natural enemies.

“…Trichogrammatids are utilized as potential bio-control agents in integrated management of lepidopteran pests of various crops (Chailleux et al, 2013;Corrigan and Laing, 1994;El-Arnaouty et al, 2014). Their ability to provide 100% parasitism in favourable conditions and their amenability to rearing have made them one of the most widely used bio-control agents.…”

The effect of temperature on different Trichogramma spp. is an aspect to be understood for planning mass production strategies and further field releases. The key biological parameters of seven different spp./strains of trichogrammatids (viz. Trichogramma japonicum Ashmead, T. cordubensis Vargas and Carbello, T. achaeae Nagaraja and Nagarkatti, four strains of T. chilonis Ishii i.e. lab strain, Nilgiris strain, Kodaikanal strain and a strain acclimatized to constant 15°C) were investigated at five constant temperatures (16, 21, 26,. The different test temperatures had a significant impact on the biological parameters of the different species/strains. Based on longevity, parasitism and fecundity attributes, the best temperature to propagate these trichogrammatids was found to be 26°C. Considering the higher parasitism rates and the ability to parasitize and remain fecund at varied temperatures, T.chilonis Nilgiris strain proved to be the best. From the linear model of regression analysis, the upper temperature thresholds ranged from 35 to 46.37°C and the lower temperature thresholds were recorded to range between 9 and 12°C, with T. cordubensis appearing to be least temperature sensitive.

“…Various predators and parasitoids have been reported naturally attacking T. absoluta in tomato crops in Europe and North Africa and more recently in India and South America (Biondi, Desneux, Amiens‐Desneux, Siscaro, & Zappalà, ; Calvo, Soriano, Stansly, & Belda, ). Some efforts have targeted the activity of the T. absoluta egg (Cabello et al., ; Chailleux et al., ; El‐Arnaouty et al., ; Martins et al., ) and larval parasitoids (Biondi et al., ; Chailleux, Desneux, Arnó, & Gabarra, ). However, the most cost‐effective and successful biological control programmes are those based on the augmentation and/or conservation of Miridae bugs, such as the omnivorous M. pygmaeus and N. tenuis , employed alone or in combination with parasitoids (Chailleux, Biondi, Han, Tabone, & Desneux, ; Chailleux, Bearez, et al., ; De Backer et al., ; Naselli et al., ) or with selective pesticides (Zappala et al., ).…”

The seasonal variation in natural mortality of phytophagous insects is determined by the relative importance of biotic and abiotic factors in agroecosystems. Knowledge regarding these factors throughout the year represents a key concern for IPM programmes. Seasonal population fluctuations of tomato pinworm, Tuta absoluta, led to an investigation of its natural mortality factors during the rainy season when the population level is low and during the dry season when population peaks occur. The aim of this study was to verify the seasonal variation in T. absoluta mortality factors in tomato crops. Immature stages of T. absoluta were obtained from laboratory‐rearing in the laboratory. These were taken to the field and monitored over two years. The mortality causes for each stage of insect development from egg to adult were assessed daily. Multiple biotic and abiotic mortality factors affected the immature T. absoluta stages such as rainfall, physiological disturbances, diseases, parasitoids and predators. The key T. absoluta mortality factor during summer–spring was predation. In addition, larvae predation correlated positively with temperature, wind velocity, photoperiod and rainfall. Nevertheless, during winter–fall, the key mortality factor was parasitism. Therefore, the critical stage for mortality was 3rd‐ and 4th‐instar larvae, being more vulnerable to natural control factors. Finally, the results showed the importance of vertical and horizontal action on natural mortality factors.
