Thrips setosus Moulton was found to be a new vector of tomato spotted wilt virus (TSWV) at Gojo, Nara Prefecture. The insects were commonly observed on tomato plants, Sonchus oleraceus L. and Youngia japonica (L.) DC. naturally grown around tomato fields. Frequent occurrence of TSWV was observed in these two weeds around the heavily infested tomato fields. These weeds may play an important role as a overwintering host and a reservoir of TSWV at Gojo.
A Pyricularia isolate from goosegrass, Eleusine indica (L.) Gaertn., produced perithecium like structures (PLSs) scatteringly around the inoculum on oatmeal agar. The PLS consisted of peridium, 134 (74-234)μm in diameter and beak, 84 (46-133)μm in width×528 (122-1313)μm in length. The PLS was morphologically indistinguishable from the perithecium produced at the junction of both mycelia by matings between the isolate and other isolates from some Graminacious plants. But, neither asci nor ascospores were produced in the peridium of the PLS. This isolate was considered to be hermaphroditic.
