چکیده

the effect of four concentrations (0.5, 1, 2.5, and 5 mg/lit) of two insect growth regulators ‎‎(igrs) of buprofezin and pyriproxifen on 1 and 4-day eggs, different nymphal instars, and ‎pupae of trialeurodes vaporariorum (homoptera: aleyrodidae), was studied at 26 ± 2 °c, 80 ± ‎‎5% rh, and 16: 8 (l: d) on lantana camara in the greenhouse. the effect of both igrs was ‎positively related to increasing of concentrations. the susceptibility of one-day eggs of t. ‎vaporariorum to the insecticides was more than four-day ones, and also early nymphal instars ‎‎(1st and 2nd) than 3rd, 4th, and pupa. the mean percentage of adult eclusion from first to fourth ‎nymphal instars and pupa in 2.5 mg/liter of pyriproxifen was 0, 0, 0, 61.32 ± 11.06, and ‎95.73 ± 3.66, in 5 mg/liter of it was 0, 0, 0, 54.16 ± 10.55, and 98.09 ± 1.14, in 2.5 mg/liter of ‎buprofezin was 19.88 ± 7.67, 48.35 ± 12.05, 60.28 ± 11.34, 85.84 ± 7.18, and 91.85 ± 6.55, and in 5 ‎mg/liter of it was 12.15 ± 4.60, 34.72 ± 8.96, 45.92 ± 7.87, 79.27 ± 8.95, and 92.28 ± 7.13 percent, ‎respectively. ‎

Reproduction and development of Eretmocerus eremicus (Hymenoptera: Aphelinidae) on Trialeurodes vaporariorum (Homoptera: Aleyrodidae)

Eretmocerus eremicus is the most abundant parasitoid of the Bemisia complex in North America. It can parasitize equally successfully the most common whiteflies in greenhouses, Trialeurodes vaporariorum and the Bemisia complex. The parasitoid is used in Europe for whitefly control, either alone or in combination with releases of Encarsia formosa. Life-cycle and demographic parameters of this par...
