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 کاملMolecular Evidence of Polyandry in the Citrus Mealybug, Planococcus citri (Hemiptera: Pseudococcidae)
The occurrence of polyandry in Planococcuscitri, presumed by earlier observations of mating behavior, was confirmed using microsatellite genotyping of pools of over 400 eggs resulting from controlled crosses of one female with two males. The genetic contribution of both mated males was confirmed in 13 out of 43 crosses. In three crosses it was possible to determine that only the first male fert...

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...
