Abstract

The lifecycle of Bactericera cockerelli was evaluated on the tomato varieties ‘Charanda F1’ and ‘Rafaello’, under greenhouse conditions at the Colegio de Postgraduados, Campus Montecillo, Texcoco, Mexico, during October–December, 2009 and January–March, 2010. A line of B. cockerelli dating from 10 years ago free from agrochemical applications was used. The adults were kept in individual growth chambers. The parameters measured were average life expectancy (ex), net reproductive ratio (Ro), time of generation (T), intrinsic natural increase ratio (rm), finite increase ratio (λ), births (b), and mortality (d) in each of the varieties. For the October–December cycle, reproduction began at 34 days in the ‘Charanda F1’ variety, and at 41 days in January–March. The incubation period for the eggs was 7–13 days, with a nymphal period of 32–37 days in ‘Charanda F1’; in ‘Rafaello’, incubation took 8–10 days, with a nymphal period of 31–35 days. The lifecycle in Charanda F1 was 63–69 days, and was 68–70 days in Rafaello. The accumulated fecundity of the females was 3,426–3,200 eggs in Charanda F1 and 2,142–2,099 eggs in Rafaello.
