Survey of leafminers and their parasitoids to find endosymbionts for improvement of biological control

摘要: Abstract Agromyzid leafminers cause serious pest problems in Japan. These are parasitized by their native parasitoids. The objective of our research is to find symbionts that may be useful improving the biological control using parasitoids Among four species leafminers, we detected two strains Wolbachia from Liriomyza trifolii (Burgess) (Diptera: Agromyzidae) and bryoniae (Kaltenbach) Agromyzidae). Although induces strong cytoplasmic incompatibility (CI) L. , level infection population was not fixed it maintained at frequencies must regarded as unstable. 15 leafminer parasitoids, found a Hemiptarsenus varicornis (Girault) (Hymenoptera: Eulophidae) Rickettsia Neochrysocharis formosa (Westwood) Eulophidae). H. observed infected with very similar . This strain did induce CI or parthenogenesis N. thelytokous practically all populations were studied, has reached fixation. Many including belong family Eulophidae. It possible used render other Eulophidae well method increase efficiency.
