متن کاملHarmful supernumerary chromosomes in a mealy bug population.
HE supernumeraries, or B chromosomes, of the mealy bug, Pseudococcus obscurus, have been shown to undergo preferential segregation both in oogenesis and in spermatogenesis (NUR 1962a). In a female with two supernumeraries, they do not pair during the first meiotic division but usually pair and segregate regularly in the second division. However, when one or an odd number is present the unpaired...
متن کاملComparison of the Suitability of Four Commercial Pistachio Cultivars to the Pistachio Green Stink-bug, Brachynema germari, under the Laboratory Conditions
The pistachio green stink-bug, Brachynema germari Kolenati (Hem.: Pentatomidae), is an important pest of pistachio in Iran. In this research, the effects of four commercial pistachio cultivars that are commonly grown in Iran including Kaleghochi, Ahmadaghaii, Ohadi and Akbari were evaluated on the biology (developmental time, mortality rate, longevity) and demographic parameters of <em...
متن کاملEcology and management of grapevine leafroll disease
Grapevine leafroll disease (GLD) is caused by a complex of vector-borne virus species in the family Closteroviridae. GLD is present in all grape-growing regions of the world, primarily affecting wine grape varieties. The disease has emerged in the last two decades as one of the major factors affecting grape fruit quality, leading to research efforts aimed at reducing its economic impact. Most r...

The coccinellid Cryptolaemus montrouzieri Muls. is an oligophagous predator that is used to control mealy bugs in the orchards and greenhouses. Citrus soft scale, Pulvinaria aurantii, as an active pest on citrus plants in North of Iran is also attacked by this predator. This research was conducted to study biological characteristics of C. montrouzieri on citrus soft scale and mealy bug, Planoco...
