| Abstract |
Two products of Neem plant (Azadirachta indica), i.e. NeemAzal T/S (1%) and Neemix (4.5%), and Mint oil, (a commercial product from Spearmint plant, Mintha sativa) were evaluated for there effects on the adult female of Tríchogramma evanescens Wostwood (Hymenoptera: Trichogranunatidae), an important egg parasitoid. At the same time, their effects on hatchability of Agrotis ipsilon HUfn. eggs were estimated. It was found that, the three products were effective against the black cutworm eggs, as they cause an increase in the percentages of un hatched eggs which estimated by 63.98, 71.37 and 86.26 % when treated with NeemAzal, Neemix and Mint oil, compared with control (9.004%). Exposure of the adult parasitoid to Neemix and NeemAzal T/S did not affect the percentage of parasitism (79.98% and 78.57%), but Neemix increased fecundity of the emerged adult parasitoid to 60 progeny/ female compared with control (37.67 progeny/female). Exposure to Mint oil minimized the percentage of parasitísm to 53.91%, reduced fecundity of emerged adults to 20.75 progeny/female. Meanwhile, NeemAzal T/S decreased fecundity of the emerged adult (33.4 progeny/female), and affected drastically on the percentage of progeny survival and reduced it to 57.06%.
