The feeding, fecundity and mortality of Liriomyza trifolii (Burgess) on the chrysanthemum cultivar 'Kyura-Kids' were determined in no-choice experiment and were compared with those on three other cultivars. There were no differences among cultivars in numbers of puncturing females, oviposition females and fertilized egg oviposition females. Number of feeding punctures, number of eggs laid and number of hatched larvae were not different among four chrysanthemum cultivars, while number of pupae fed on 'Kyura-Kids' were extremely small among them. This indicated that the resistance to L. trifolii of 'Kyura-Kids' reported on the basis of the field experiment was caused by high larval mortality.

The spider mite, Tetranychus takafujii Ehara and Ohashi,2002, is known to occur mainly on weeds and black nightshade in Tokyo, Osaka, Kyoto and Hyogo prefectures on Honshu island. In 2007, T. takafujii was found to cause heavy damage to cherry tomatoes in Kagoshima on Kyushu island. To test the possibility of chemically controling this spider mite, we tested its susceptibility to 18 acaricides/pesticides available for tomato and other vegetables in the Solanaceae using a leaf dip method. Spider mite females were highly susceptible to most acaricides/pesticides, except Etoxazole SC and Spirodiclofen SC which are categorized as slow-acting. Spider mite eggs were also highly susceptible to many of treatments, except Malathion EC, Bifentrin 2.0% WP, Emamectin benzoate EC, Chlorfenapyr SC and Bifenazate SC. Egg hatchability at day 4 were ranged from 24.7% to 89.4% among the treatments, and most neonate larvae died after 1 day of Emamectin benzoate EC, Chlorfenapyr SC and Bifenazate SC treatments. Results suggest that many of the treatments tested will be effective in controlling of T. takafujii either at the egg, larval or adult stage.

Nested PCR amplification of a Spodoptera litura nucleopolyhedrovirus (SpltNPV) lef-8 gene fragment was performed on egg masses and larvae of S. litura, and resulted in detection of a latent SpltNPV in 20.0% of “healthy” laboratory stock samples, and in 22.6% of samples collected at different periods and in remote places in Kagoshima Prefecture. The PCR product sequences showed 99% similarity to the published lef-8 sequence of SpltNPV, confirming that the amplification products were derived from SpltNPV. Further, cross-inoculation of laboratory stock S. litura larvae with Mythimna separata NPV (MyseNPV) activated the latent virus, which provoked a change in the virulence of MyseNPV samples collected from cadavers of S. litura. Our data suggest that caution should be taken when using S. litura as a host to produce heterologous NPVs.

Species Composition and Hostplants for Liriomyza trifolii and L sativae Inside and Outside of Plastic Greenhouses in the Southern Part of the Satsuma Peninsula in Kagoshima Prefecture . Journal of the Japanese Society of Agricultural Technology Management15 ( 1 ) 35 - 43 2008.6Reviewed International coauthorship

A survey in the southern part of the Satsuma Peninsula in Kagoshima Prefecture, Japan, found 63 host plant species from 15 families associated with Liriomyza trifolii and 53 species from 10 families associated with L. sativae. The two Liriomyza species co-occurred in most greenhouses (inside) and also on open vegetable fields near greenhouses (outside). Outside greenhouses, the number of host plant species mined by larvae declined from February to April, although mining larvae were found even in winter. In greenhouses containing Chrysanthemum and qing-geng-cai, L. trifolii was dominant. The two Liriomyza species co-occurred at equal density in greenhouses containing ornamental flowers and cherry tomato, while L. sativae dominated in greenhouses containing squash and leaf vegetables. Outside greenhouses, L. trifolii was dominant around Chrysanthemum greenhouses, and, in spite of cultivated plants, the two species co-occurred at equal densities around ornamental flower greenhouses; L. sativae was dominant around squash and cherry tomato greenhouses. The relative dominance of L. trifolii or L. sativae depended on the cultivation management and the existence of suitable host plants. Exceptionally, on some species of squash cultivated around greenhouses, we found L. trifolii in the 2005 and 2006 surveys, but not in the 2004 survey.
