The relative abundance of the reproductive types of Thrips tabaci Lindeman was occasionally surveyed by collecting female adults from the foliage of commercially grown Welsh onions, onions, and cabbages at various locations in Kyoto Prefecture between 2016 and 2018. Arrhenotokous females were found at 39 of the 46 surveyed sites and coexisted with thelytokous females at 26 sites, of which the arrhenotokous composition was higher than that of thelytokous at 19 sites. The arrhenotokous type was dominant in Kyoto City and Kumiyama Town, and thelytokous females were found to be dominant in the areas north of Fukuchiyama City. In cabbage, only arrhenotokous females were observed. The seasonal composition of T. tabaci reproductive types was additionally surveyed in Welsh onion plants grown in greenhouses in Kameoka City, Kyoto Prefecture, between November 2016 and June 2019. Thelytokous females were dominant between November 2016 and March 2017 and arrhenotokous females dominated between April 2017 and March 2018, except for January 2018. After May 2018, the thelytokous type dominated again.

Phytoseiid mite species were surveyed on garden and wild plants in an experimental field in Japan. The above-ground part of the plants were collected from the field, and dried in the laboratory to collect phytoseiid mites from the plant-parts. When the plant-parts were dried on the bean leaflets rearing Thrips tabaci larvae, phytoseiid mites on the plant-parts moved to and remained on the leaflets during two-day treatment. Populations of Typhlodromips sessor and Neoseiulus makuwa were established when fed on T. tabaci. Then, the life history parameters of both species were examined in the laboratory. In comparison with the data from previous studies, the daily oviposition of both species was similar to that of Amblyseius eharai, Neoseiulus barkeri, and Neoseiulus cucumeris, and the survival rate during the development of both species was similar to that of N. barkeri. The mode of reproduction of T. sessor was confirmed by the experiment as parthenogenetic thelytokous reproduction.

We examined the susceptibility of two populations of soybean pod borer, Leguminivora glycinivorella Matsumura（Lepidoptera: Tortricidae）, in Tottori Prefecture to five insecticides: diamides（chlorantraniliprole and flubendiamide）, organic phosphorus（MEP）, synthetic pyrethroid（etofenprox）, and neonicotinoid（acetamiprid）. For both populations, we detected decreasing susceptibility to diamides and synthetic pyrethroid, and organic phosphorus and neonicotinoid were highly toxic. Soybean farmers in Tottori Prefecture use chlorantraniliprole and etofenprox, but not flubendiamide, for pest control, suggesting that cross-resistance may develop between chlorantraniliprole and flubendiamide. To manage diamide resistance in the soybean pod borer in the future, pest management systems should be updated or improved.
