Abstract


Liriomyza sativae is the world's most serious and dangerous polyphagous leafminers one of. Reed lattice Eulophidae as natural enemies of leafminer in the world, not yet reported, its biology is a blank. Requirements for environmental protection and sustainable development, the development and utilization of new natural enemies to control Liriomyza damage this experiment, the biology of the bee made a detailed study of the system. The main findings are as follows: 1. Artificial climate chamber set different temperature and humidity, lighting conditions, record the developmental duration bee different instars. The results show that: the temperature is not affect the duration of the most important factors of various stages of development, the impact of relative humidity and illumination time. Developmental duration in the range of 15 ℃ ~ 30 ℃ instars shortened with increasing temperature, developmental duration was negatively correlated with temperature. 5 ℃ cold storage bees and pupae seven days, its survival and emergence rate of more than 98%. With the increase in storage days, survival and emergence rate declined sharply. 2. Cage cover, record the number of male and female individuals feeding lethal number of each pair of bee life and fecundity, and Aberdeen bee. The results show that: the female bee life of up to 17 days, about six days than drones. The male and female bees than 0.9:1. Bee 6:00-14:00 feeding the fatal number and spawning accounted for 66% of the day. 22:00-6:00 The bee feeding and oviposition. Bee daily fecundity in copulation after nine days of the formation of two parasitic peak. Feeding lethal Trends and parasitic same, they have a certain correlation. 3. Fed different food record the life and female bee bee fecundity. The results show that: 5% honey water pollen solution can significantly extend the life and the female bee bee fecundity. 4. Use the setting of the male and female bee mating than control mating time visit bee breeding. The results show that: the mating than larger every female fan bee number, and the small role of the mating time. In mating than the same to extend beneficial to increase the number of fan bee mating time. The bee Parthenogenesis of producing male bees. 5. Supply does not host instars larvae bee host selectivity. The results show that: the bee feeding 1,2,3 instar host larvae, but only at the end of the second instar and third instar hosts spawning. The most suitable host for the third instar sativae larvae. 6. Bee Feather shortly after they mate. The the female bees after mating will along the latent Road Search host and choose to lay their eggs at the end of the second instar or third instar host. Bee generally more active in the morning, from 16:00 to 6:00 the next day, basically do not eat nor moved. Blooms later and further research results above about reed Eulophidae of developmental biology and reproductive biology, basic theoretical basis, and thus has a certain theoretical and practical significance.
