Abstract

 Woolly poplar aphid, PHLOEOMYZUS PASSERINIII Sign., is considered to be a major insect pest of poplar trees in Iran. This aphid causes serious injury to poplar trees in Hamadan province. In this study, stable population parameters of woolly poplar aphid P. passerinii were evaluated in growth chamber on twelve poplar CLONEs of four species namely, POPULUS alba (p.a), POPULUS nigra, POPULUS del/oides and POPULUS x euramericana. A poplar cut from each CLONE was infested with a single newly born aphid, and the reproductive processes were recorded in a controlled condition 21± 1 Celsius, 60-70% RH, and photoperiod of 16:8 (L: D). Subsequently, the experiment was carried out with 18 replications and the aphid fecundity and death rate was recorded until the end of lifespan. Thereafter, stable population parameters were calculated on each CLONE. The aphids could not reproduce on a number of CLONEs including, P. alba 58/57, P. deltoides 72/51 and P. euramericana 214, showing the immune response in these CLONEs. Intrinsic rate of increase (rm) (0.38) and net reproductive rate (Ro) (62.72 nymph per female) on p.n 56/72 was higher than remaining CLONEs. The rm on p.n 47/13, p.n 56/32, p.n 74/1 and p.n 75/2 were about 0.26-0.34, and the varied within 23.67- 41.00, which these CLONEs were semi susceptible. However, rm and R0 on the resistant CLONE (p.d missoriensis) was 0.03 and 1.39. Other stable population parameters of the aphid such as gross reproductive rate, mean generation time, doubling time, intrinsic death rate, intrinsic birth rate and finite rate of increase were also calculated on different CLONEs.
