Abstract
Area-wide management of Asian citrus psyllid, Diaphorina citri Kuwayama, might use predators abundant in citrus orchards, making necessary the assessment of local predatory species such as Ceraeochrysa valida (Banks). The objective of the study was to determine the life cycle of C. valida under different rearing conditions; its fecundity, survival, and longevity; and its predatory capacity on different larval instars of D. citri, both in the laboratory and greenhouse. Predators and pests were reared from insects collected in citrus orchards in the central coastal area of Veracruz, Mexico. Developmental time for C. valida eggs; larvae 1, 2, and 3; and prepupae-pupae were 5.5 ± 0.7, 6.5 ± 0.7, 5.0 ± 1.0, 7.0 ± 1.0, and 14.5 ± 0.7 days, respectively. Male and female longevities were 74.0 ± 38.9 and 78.0 ± 28.9 days. Mean daily number of eggs per female was 10.0 ± 8.4. Predation in the laboratory and greenhouse was greater on older larvae (P < 0.0001) regardless of the nymphal stages consumed. In the laboratory, C. valida consumed as many as 368 prey in 48 hours. However, consumption in a greenhouse was not as much as in the laboratory during the first 6 hours.
