Abstract
The tomato leaf miner, Tuta absoluta (Meyrick) (Lepidoptera: Gelechiidae) is an invasive pest, that caused a significant damage to the tomato crop in the Middle East area. It infests Solanaceae plants especially tomato, Lycopersicon esculuntum Mill. To find parasitoids and predators for biological control of this pest, samples of tomato leaves infested with T. absoluta were collected from Qualiobya and Giza Governorates. Three genera of hymenopterous parasitoids, Diglyphus sp. (Eulophidae), Elasmus spp. (Elasmidae) and Telenomus sp. (Scelionidae) are the first record in Egypt. The predator bug, Nesidiocoris tenuis Reuter (Heteroptera: Miridae) was also recorded. T. absoluta showed two peaks of 30.3 and 25.0 leaf mines/10 leaflets on 7th and 28th of May, 2013, respectively. N. tenuis also recorded two peaks of 58.8 and 73.3 nymphs and adults/plant on the same previous dates, respectively. N. tenuis was mass reared to evaluate the predatory efficiency of nymph and adult stages on T. absoluta eggs. The nymph, adult male and female consumed 113.3, 81.5 and 125.3 eggs of T. absoluta, respectively. The 4th nymphal instar devoured the highest number (30.6 eggs), while the 1st nymphal instar ate the lowest (7eggs). Therefore, N. tenuis was highly effective in controlling T. absoluta eggs under laboratory conditions.
