The life history and life table of Bemisia tabaci Gennadius on cucumber was studied under laboratory conditions at 20, 25 and 30 degrees C. The overall developmental time varied from 34.8 days at 20 degrees C to 14.1 days at 30 degrees C. Immature mortality decreased from 45.8 to 17.3% with increasing temperature. The threshold temperatures of egg, 1st,(More)
Reproductive parameters and ovipositional preference of Plutella xylostella were assessed on some mutant genotypes of canola (RGS 8-1, RGS 102, RGS 8-13, Zar 9-9 and Talaye 8-3) and their cultivars (RGS, Zar, Talaye) under greenhouse condition (21 ± 6 °C, 65 ± 10 RH and a photoperiod of 16L: 8D h). Comparison of the reproductive parameters on RGS and its(More)
Nasonovia ribisnigri (Mosely) is one of the most important pests of the lettuce plant and it was reported for the first time in Ahvaz in 2008. In order to investigate the dominant species of its natural enemies and their population fluctuations, sample were taken arbitrarily from fifty plants twice a week during the growing season in 2010-2012. In this(More)
As an agricultural modernization, gamma irradiation is an important method for enhancing crop yield and quality. Nevertheless, its use can alter other plant traits such as nutrition and resistance to different biotic/abiotic stresses that consequently affect plant–insect interactions. A tritrophic system was utilized based on two canola mutant lines(More)
Laboratory experiments were conducted to measure the functional and numerical responses of Eretmocerus mundus Mercet parasitizing cotton whitefly, Bemisia tabaci Gennadius. Parasitoids were isolated singly for 24 h in 5 cm petri dishes with either 5, 10, 20, 40, 60 or 100 second nymphal stages of B. tabaci. Results showed a typical type II functional(More)
