Influences of temperature on interspecific competition between Liriomyza sativae and L.huidobrensis
The pupae, adults and percentage of adult emergence were evaluated by putting L. Sativae (1♀: 1♂) and L. Huidobrensis (1♀: 1♂) into glass tubes at different temperatures (18, 25, 30 ℃) to study the effects of temperature on interspecific competition and displacement between Liriomyza sativae and L. Huidobrensis .The results showed that there was significant difference in the number of F1 adults between L. Sativae (0.4±0.3) and L. Huidobrensis (2.5±0.7) at 18℃ ; at 25 ℃ , the number of L. Sativae adults (7.6±3.0) were more than that of L. Huidobrensis adults (4.3±2.0) in F1 progenies, but had no significant difference-, at 30 ℃,there were only L. Sativae adults (18.0±2.9) in F1 progenies. The results indicated that temperature was a key factor in interspecific competition between the two leafminer species.
