DEL TORO-BENITEZ, Marbely et al. Biology and population parameters of Aphis gossypii Glover (Hemiptera: Aphididae) on pepper (Capsicum annuum L.) and egg plant (Solanum melongena L.). Rev. Protección Veg. [online]. 2016, vol.31, n.2, pp. 87-93. ISSN 2224-4697.

The biological and population attributes of Aphis gossypii (Glover) (Hemiptera: Aphididae) were evaluated on eggplant and pepper under laboratory conditions. One hundred newly hatched nymphs were individualized in Petri plates containing leaf discs of eggplant and peppers on 1% agar water. Daily observations were made to determine the changes of moults, and the duration of the different instars to reach adulthood and mortality of nymphs was recorded. A. gossypii had a development cycle of 5.97 days on egg plant and 5.29 days on pepper, with a life cycle of 11.91 and 9.97 days, respectively. On eggplant and pepper, respectively, the r_m for this species was 0.089 and 0.05, the generation time of 20.72 and 24.57,and the Ro of 6.33 and 3.73 female daughters per mother. The biological parameters of A. gossypii on pepper and eggplant showed that on eggplant the life cycle is lengthened, the generation time is shortened, and the progeny increases.
