Laboratory rearing and life history of Liriomyza sativae (Diptera: Agromyzidae) on lima bean
Environmental Entomology 23 (6), 1416-1421
Abstract: A life table study with five replicates was conducted through age 9 d at 25°C with eight male and eight female Liriomyza sativae Blanchard caged with a lima bean plant (Phaseolus lunatus L. 'Henderson') and provided honey. Oviposition peaked in 2- to 6-d-old adults. Overall, 80% of females but only 50% of males lived to age 9 d. Fecundity through adult age 9 d in four cohorts ranged from 1,355 to 1,737 offspring, but one cohort produced only 569 offspring. In a separate experiment at 25°C, fecundity through age 9 d by cohorts of eight small (mean = 435 µg) versus eight large (mean = 731 µg) females with males was 1,461 and 2,038 offspring, respectively. Effect of leafminer size on life history parameters at 25°C was examined more specifically by providing a male-female pair (each of known pupal weight) with a lima bean plant and honey each day until death. Males were removed after 8 d to standardize female exposure to males. Mean longevity of the 33 females weighing an average of 667 µg was 27.1 ± 1.8 d (mean ± SEM) with females producing 362 ± 30.8 offspring. Net reproductive rates (R_o) of females weighing <550 µg, from 550 to 700 µg, and >700 µg were 170, 166, and 197 female offspring per female, respectively. Placement of L. sativae pupae in 20, 40, 60, 70, 80, 90, and 95% RH regimes at 25°C within 30 min after dropping from leaves resulted in 49, 81, 90, 97, 100, 99, and 94% survival to adult eclosion, respectively.
