Title

COMPARISON OF APPARENT AND MARGINAL PARASITISM OF EGG PARASITOID OF GRAPE LEAFHOPPER ARBORIDIA KERMANSHAH DELABOLA (HEM., CICADELLIDAE) IN DIFFERENT CLIMATIC REGIONS OF ISFAHAN, IRAN

Abstract

 Eggs of GRAPE LEAFHOPPER Arboridia kermanshah Delabola (Hem., Cicadellidae) are attacked by two parasitoid species Anagrus atomus L. (Hym., Mymariade) (species A) and Ufens sp. (Hym., Trichogramatidae) (species B) in Isfahan vineyards, Iran. For this research, 27 vineyards were selected randomly in different climatic regions of Isfahan. Ten plants were selected randomly per hectare of each vineyard and 3 leaves were sampled on each plant from lower, middle and upper strata. Then healthy and parasitized eggs were counted and the percentage of apparent parasitism was calculated in each vineyard. Three samples that each including 30 parasitized leafhoppers eggs were selected randomly from different climatic regions and the number of wasps were recorded. The percentage of MARGINAL PARASITISM was calculated and compared for the two species. The average percentage of apparent parasitism in area of study was 8.33 that its range was varied at least 1.5 percent in very hot with dry desert up to 43 percent in dry temperate cold desert. The semi cold with warm and dry desert and semi-arid cold with dry desert climatic region with an average 82.8 percent had the highest percentage of MARGINAL PARASITISM for species A and very hot with dry desert climate with an average 4.9 percent had the highest percentage of MARGINAL PARASITISM for species B. The MARGINAL PARASITISM of both species had moderate to high correlation with the percentage of apparent parasitism. The correlation coefficient of, in other words, the apparent parasitism was increased by increasing its MARGINAL PARASITISM in climatic regions. While the correlation coefficient of species B was negative the apparent parasitism was decreased by increasing its MARGINAL PARASITISM in climatic zones. Based on data obtained, it can be interfed that A. atomus was more efficient than Ufens sp. in different climatic regions of Isfahan province.
