Two lace bug genera, Baeochila Drake & Poor, 1937 and Idiocysta China, 1930 (Hemiptera: Heteroptera: Tingidae) are recorded from Japan for the first time, and two new species, B. horvathi sp. nov. and I. takarai sp. nov., are described. The former was collected from the vines of Hedera rhombea (Miq.) Bean (Araliaceae) and the bark of Trachycarpus fortunei (Hook.) H.Wendl. (Arecaceae) in suburbanized areas of Honshu, Shikoku and Kyushu, and the latter was collected from the leaves of Freycinetia formosana Hemsl. (Pandanaceae) in the laurilignosa ecosystem of the Ryukyu Islands. The distribution ranges and host plant relationships of the two new species are discussed. Keys to all species of the two genera and photographs of living individuals for the new species are also presented.

Hedera Rhombea

The structure-activity relationship of 12 isolated acetylenes from galls of Hedera rhombea (Araliaceae) induced by Asphondylia sp. (Cecidomyiidae) and their derivatives has been studied for the inhibition of the shoot and root growth of rice, perennial ryegrass, cockscomb, lettuce, and cress. Almost all acetylenes generally showed growth inhibitory activity. The diacetylenes exhibited higher activity than the monoacetylenes, suggesting that a conjugated diyne segment is essential for the activity. On the other hand, the acetylenes with a nonoxidated methylene group at C-8 showed stronger activity comparing with those possessing hydroxy and acetoxy groups at C-8. Furthermore, it has been demonstrated that the acetylenes bearing a terminal olefinic group at C-16,C-17 enhanced the activity. It is thus clarified that important sites for the activity of the acetylenes from galls of H. rhombea are a conjugated diyne and a terminal olefinic group connecting to the aliphatic chain and that less oxidated compounds show more activity.

Hedera Rhombea

Plant growth inhibitory polyacetylenes have been isolated from the insect galls on flower buds of Hedera rhombea Bean (Araliaceae) formed by the ivy flower bud gall midge, Asphondylia sp. (Cecidomyiidae), and their structures elucidated by spectroscopic and chemical means. The EC50 values for roots/hypocotyls growth of cress ( Lepidium sativum L.) seedlings were 7.0×10−5/8.0×10−5 M for ( Z)-8-acetoxy-1,2-epoxy-3-oxoheptadeca-9-ene-4,6-diyne, 9.5×10−5/9.0×10−5 M for ( Z)-8-acetoxy-3-oxoheptadeca-1,9-diene-4,6-diyne, 2.5×10−5/5.5×10−6 M for ( Z)-8-acetoxy-1-methoxy-3-oxoheptadeca-9-ene-4,6-diyne, and 7.5×10−5/2.0×10−6 M for falcarindiol, respectively. On the other hand, 8-acetoxyfalcarinol exhibited lower inhibition on roots and hypocotyls growth. Among these compounds, ( Z)-8-acetoxy-1-methoxy-3-oxoheptadeca-9-ene-4,6-diyne exhibited the strongest inhibitiory effect on root growth of cress seedlings, whereas against hypocotyl growth of cress seedlings, falcarindiol showed the strongest inhibition.
