“…The other eggs were put on fresh tomato leaves which were placed on wet cotton pieces at petri-dish (30 cm) to obtain newly hatched larvae (1st instar larvae). After hatching the larvae go through four instars, which completed in about 20 days, i.e., each instar spends 4-5 days to transfer to other one under laboratory condition (Attwa et al 2015;El-Shafie 2020).…”

Background Macrolophus caliginosus Wagner is one of the most important polyphagous predatory mirid bug that attack many agriculture insect pests. Methods The present study was carried out to show the effect of different prey stages as Tuta absoluta (eggs and fourth larval stage), Bemisia tabaci (eggs and three nymph stages) and Aphids gossypii (1st nymph stage) on the life cycle and consumption rate of male and females of M. caliginosus as predator under laboratory condition. The experiments were started by collecting the first stage of M. caliginosus nymph and placed separately on acalypha plants situated on saturated cotton pads inside Petri dishes with an excess of each prey. Results The results showed that the developmental period of the total immature stages of M. caliginosus female are affected by type and stage of tested prey. So, the duration of larval stages of female was significantly recorded the longest in case of feeding on eggs of T. absoluta compare to 1st nymph of A. gossypii. In addition to extension the adult longevity of female M. caliginosus, which fed on the 1st nymphal instar of B. tabaci more than the other pests. The consumption rate of total immature stages and adult M. caliginosus female were fed on eggs of B. tabaci was more than the other test pests. While the consumption rate of total immature stages and adult of male M. caliginosus were fed on eggs of B. tabaci was higher than that of the other pests. Conclusions The search was given the highlight focus on ability of mirid bugs to consume different insect species “stages” that might be facilitate rear predatory bugs under laboratory condition.

The remarkable biological and evolutionary adaptations of insects to plants are largely attributed to the powerful chemosensory systems of insects. The tomato leaf miner (Tuta absoluta) is a destructive invasive pest with a global distribution that poses a serious threat to the production of nightshade crops, especially tomatoes. Functional plants can attract or repel insect pests by releasing volatiles that interact with the olfactory system of insects, thereby reducing the damage of insect pests to target crops. However, there is limited research on the interaction between T. absoluta olfactory genes and functional plants. In this study, 97 members of the putative odorant-binding protein (OBP) family have been identified in the whole genome of T. absoluta. Phylogenetic analysis involving various Lepidopteran and Dipteran species, including D. melanogaster, revealed that OBP gene families present conserved clustering patterns. Furthermore, the Plus-C subfamily of OBP showed extremely significant expansion. Moreover, the expression levels of the OBP genes varied significantly between different developmental stages; that is, the highest number of OBP genes were expressed in the adult stage, followed by the larval stage, and fewer genes were expressed in high abundance in the egg stage. On the other hand, through a Y-tube olfactometer, we identified a functional plant—Plectranthus tomentosa—that significantly repels adult and larval T. absoluta. Finally, we screened the OBP genes in response to tomato and P. tomentosa volatiles at the genomic level of T. absoluta using RT-qPCR. These results laid a good foundation for controlling T. absoluta with functional plants and further studying olfactory genes.

“…The moth originated in South America and had since moved to Europe, North Africa, Asia, and the Middle East respectively [4]. Moreover, it affects tomatoes grown for both fresh and processed markets, with larvae causing up to 100 % losses when no effective control strategies are used [5]. Tuta absoluta has a high reproductive capacity, with the ability to produce up to 12 generations per year under ideal conditions [6].…”

Since 2010, Lebanese tomatoes production has been threatened by the tomato leaf miner, Tuta absoluta (Meyrick) (Lepidoptera: Gelechiidae). In this context, this study aimed to evaluate the effect of six safe biological treatments (Bacillus thuringiensis, orange essential oil, pepper & garlic extract, pepper extract, garlic extract, and olive soap) in the management of Tuta absoluta on Lebanese tomatoes in organic open field conditions. Plants were treated after the first mines of this pest had appeared on leaves. We then compared the significant ability of six treatments to reduce infestation on leaves and weight loss of tomatoes fruits, in comparison with the untreated control. The results revealed that Bacillus thuringiensis treatment presented the lowest impact on tomato leaf infestation reduction and was the most effective treatment in protecting the tomatoes plants, with least reduction in weight loss of tomatoes fruits. The orange essential oil resulted as the second most effective treatment, followed by pepper and garlic extract mixed with organic olive oil soap, pepper extract mixed with organic olive oil soap, garlic extract mixed with organic olive oil soap, and organic olive oil soap. Therefore, the first two treatments are relatively effective and economically viable to organically control Tuta absoluta.
