- Abstract
The stone leek leafminer, Liriomyza chinensis (Kato), has become a serious pest on Allium spp. However, knowledge concerning the biology of L. chinensis, which affect development of control programs, is still limited. Therefore, this experiment was conducted during 2020 at Entomology Laboratory, Faculty of Agronomy, University of Agriculture and Forestry, Hue University, Vietnam to study the effects of temperature on development, longevity, feeding and fecundity of L. chinensis under laboratory conditions. Liriomyza chinensis used for the present study were collected from green bunching onion fields at Hue City, Central Vietnam and reared on green bunching onion, Allium fistulosum L. in an environmental chamber at a constant temperature of 25 ± 0.5, 27.5 ± 0.5 and 30 ± 0.5oC, 70±10% RH and a 16L: 8D photoperiod. Developmental time, longevity, feeding and fecundity were inversely proportional to temperature. Total developmental times from egg to adult emergence decreased from 20.9 to 13.4 days for temperatures from 25 to 30oC. The longevities of L. chinensis were 9.2, 10.8 and 12.0 days at 25, 27.5 and 30oC, respectively. Females made the average of 1004.2, 1716.8 and 2549.0 punctures during her lifespan at 25, 27.5 and 30oC, respectively. The females laid means of 54.2, 115.2 and 134.8 eggs at 25, 27.5 and 30oC, respectively. These data are useful for predicting population dynamics of L. chinensis under field conditions and determining the maximum proportion of susceptible individuals for facilitating improved timing of application of control measures.
