study on morphological, molecular and biological characteristics of the conifer aphid, cinara pini linnaeus (1758) (hem.: lachnidae) under greenhouse conditions
Authors
abstract
during a survey on pests of pine trees, pinus mugo turra, in april 2010 in mashhad, a colony of an aphid was observed in abundant populations on the seedlings, belongs to the subfamily cinarinae and family lachnidae, being identified as cinara pini (linnaeus, 1758). the blast sequence to c. pini in the gene bank showed that the species was most similar to c. atlantica with 93% similarity. the mean length of adults was 2.69± 0.06 mm. the base of last antennal segment has fewer than 4 setae. the final rostrum segment is longer than the basal diameter of cornicles or slightly longer than the second tarsal segment of hind legs. investigations on the biology of the aphid under greenhouse conditions of 25±2 ˚c, 45±5 rh, and 16:8 (l:d) showed that prematurity development time lasted 10 days. intrinsic rate of increase (rm) was 0.197 ♀/♀/day and the net reproductive rate (r0) was 30.67 ♀/♀/generation. the reproductive period of aphids was 12.61 days during which a total of 36.75 nymphs per female were deposited. the total length of a generation was 26.20 days.
