Effects of Temperature, Photoperiod, and Host Plants on Development and Oviposition of Liriomyza trifolii (Burgess) (Diptera: Agromyzidae)

Abstract

The effects of temperature, photoperiod and host plants on development and oviposition of Liriomyza trifolii (Burgess) were studied in the laboratory. The regression equations relating temperature (X, °C) to development rates (Y, d-1) on kidney bean (Phaseolus vulgaris) were Y= 0.0191X-0.1531 for the egg stage, Y= 0.0155X-0.1380 for the larval stage, and Y= 0.0070X-0.0710 for the pupal stage. The estimated threshold temperatures for egg, larval, and pupal development were 8.0°, 8.9°, and 10.1°C, respectively. The upper lethal temperature was about 35°C for the pupal stage. No effect was observed for different photoperiods on the developmental period of each stage on kidney bean at constant temperatures (15° and 20°C). The combined egg and larval development time was determined for kidney bean (6.5 d), pak-choi (7.0 d), eggplant (7.2 d), gerbara (7.9 d), cherry tomato (7.9 d), cucumber (8.1 d), tomato (8.3 d), celery (8.3 d), soybean (8.5 d), melon (8.7 d), and chrysanthemum (9.7 d). Of these host plants, kidney bean and pak-choi produced individuals with comparatively-high pupal weight. The longevity and fecundity of female adults were determined for nine host plants: soybean (3.9 d and 21 eggs), tomato (3.8 d and 54.7 eggs), cherry tomato (5.4 d and 75.6 eggs), melon (6.9 d and 108.0 eggs), gerbera (12.9 d and 156.4 eggs), celery (7.4 d and 205.6 eggs), chrysanthemum (27.5 d and 208.8 eggs), kidney bean (15.7 d and 540.3 eggs), and pak-choi (24.6 d and 637.7 eggs). © 1995, JAPANESE SOCIETY OF APPLIED ENTOMOLOGY AND ZOOLOGY.
