Green lacewings (Neuroptera: Chrysopidae) are voracious predators of aphids and other small, soft-bodied insects and mites. Earlier, we identified (1R,2S,5R,8R)-iridodial from wild males of the goldeneyed lacewing, Chrysopa oculata Say, which is released from thousands of microscopic dermal glands on the abdominal sterna. Iridodial-baited traps attract C. oculata and other Chrysopa spp. males i...

Microalga Nannochloropsis oculata is a promising alternative feedstock for biodiesel. Elevating its oil-yielding capacity is conducive to cost-saving biodiesel production. However, the regulatory processes of multi-factor collaborative stresses (MFCS) on the oil-yielding performance of N. oculata are unclear. The duration effects of MFCS (high irradiation, nitrogen deficiency and elevated iron ...

Microalga, Nannochloropsis oculata, is an important microorganism for feeding fish larvae. We develop a transgenic line of N. oculata that enbles to produce an antimicrobial peptide, bovine lactoferricin (LFB). An algae-codon-optimized cDNA of LFB was fused with a red fluorescent protein (DsRed) reporter and driven by a heat-inducible promoter, which is a heat shock protein 70A promoter combine...

Three known nucleosides were isolated from the sponge Haliclona sp. The structures were established on the basis of NMR data and comparison with those reported, and chemotaxonomic relationships of the sponge nucleosides were discussed.

The relationship between antifouling metabolite production and epibiosis on the surfaces of the sponges Haliclona cymaeformis, Haliclona sp. and Callyspongia sp. was investigated in this study. Densities of macrofoulers and diatoms were suppressed on the surfaces of all examined sponges, while densities of bacteria on the surfaces of H. cymaeformis and Callyspongia sp. were similar to those on ...

A new polyunsaturated brominated fatty acid possessing acetylenic bonds 1 was isolated from the Indonesian sponge Haliclona sp. The structure of compound 1 was elucidated by analyzing its spectral data. It showed moderate cytotoxicity against cultured cells.
