Enantiospecific synthesis and insect feeding activity of sulfur-containing cyclitols

The first syntheses of two deoxythiocyanocyclitols (4-deoxy-4-thiocyano-l-chiro-inositol and deoxythiocyanoconduritol F) and two deoxysulfonylcyclitol acetals are reported by a chemoenzymatic enantioselective route. The compounds were prepared by a sequence of enzymatic and ruthenium-catalyzed dihydroxylations, and the results were studied regarding reaction conditions and co-catalyst for different derivatives. The new compounds were included in a minilibrary of deoxygenated cyclitols and evaluated for their capacity to influence the feeding behavior of Epilachna paenulata (Coleoptera: Coccinellidae), a common pest of the Curcubitaceae crops.     

A microscope slide test for the evaluation of insect repellents as used with Culicoides impunctatus

An account is given of a field test suitable for evaluating insect repellents. Our test insect was Culicoides impunctatus. The test is based on the avoidance of a test substance placed within a circular chamber. It appears to be reliable and reproducible. The different components of oil of Myrica gale have been investigated and a hierarchy of activity is revealed, limonene and terpenine-4-ol being at the extremes of the range of activity.     

Identification of bloodmeals of the Scottish biting midge, Culicoides impunctatus, by indirect enzyme-linked immunosorbent assay (ELISA)

Abstract. An indirect enzyme-linked immunosorbent assay (ELISA) has been developed to identify the bloodmeal sources of Culicoides impunctatus Goetghebuer. Nightly light trapping in Scotland, between April and September 1992, caught a total of 344 blood-engorged female C. impunctatus , all in May, June and July. The insects were stored in 70% ethanol and tested 5–7 months later. Bloodmeal sources were positively identified for 246 (71.5%). Bovine hosts were most common (38.4%), followed by deer (23.0%) and sheep (9.9%). Only one midge had fed on human blood. Relatively freshly fed (<24h), fully engorged females gave the clearest results. The wider applications of the technique to the study of Culicoides host preferences is discussed.

Preliminary note on the distribution and ecology of Culicoides imicola in Portugal

Abstract. Data on Culicoides imicola were obtained during studies carried out during the recent outbreak of African horse sickness in Portugal. The previous most northerly published record of C.imicola in Portugal was 38^o40'N (Pégöes). In the present work the geographical distribution of this species is extended to the parallel of 41^o17'N. We have also confirmed the continuous presence of adult C.imicola in Southern Portugal (Alentejo and Algarve) throughout the year. In the laboratory we obtained this species from a sample of cattle faeces and from another of soil contaminated with animal excreta. In relation to host association 57.37% of C.imicola were trapped in the vicinity of pigsties. Finally, we collected 11 ,463 Culicoides of which 12.47% were C. imicola.

The Chironomidae and Ceratopogonidae (Diptera) of New Zealand’s subantarctic islands

Abstract

A taxonomic study of midges collected in the subantarctic islands of New Zealand yielded 22 species of Chironomidae and 4 of Ceratopogonidae. Only four of the chironomids occur elsewhere, three on ‘mainland’ New Zealand and one on The Snares islands. Of the 15 species found on the Auckland Islands, 11 on Campbell Island, and 5 on the Antipodes Islands, respectively 9, 4, and 2 are endemic. Nine new species are proposed in existing genera: Parochlus rennelli, P. reductus, P. gressitti, P. brevis, Telmatogeton antipodensis, Eukiefferiella heveli, Cricotopus aucklandensis, Chironomus antipodensis, and C. subantarcticus. Gressittius n.gen. is proposed for Corethra antarctica Hudson (type-species). Semiocladius n.gen. is proposed for Camptocladius crassipennis Skuse, and S. kuscheli n.sp. is described. Eight further new genera are proposed, with the following new species as type-species: Kuschelius dentifer, Mecaorus elongatus, Pterosis wisei, Hevelius carinatus, Gynnidocladius pilulus, Nesiocladius gressitti, Nakataia cisdentifer, and Maryella reducta. Genera Halirytus Eaton and Psamathiomya Deby are synonymised with Telmatogeton Schiner. Gressittius antarcticus (Hudson), Ablabesmyia mala (Hutton), Telmatogeton magellanicus (Jacobs), T. amphibius (Eaton), T. macquariensis (Brundin), Semiocladius crassipennis (Skuse), S. endocladiae (Tokunaga), and Calopsectra funebris (Freeman) are new combinations. Of the ceratopogonids, only one species occurs elsewhere in New Zealand. Three species, only one of them endemic, were found on the Auckland Islands; two were found on Campbell, of which only one is endemic. Forcipomyia kuscheli and Dasyhelea aucklandensis are proposed as new species.     

The adults of the Australian Megaloptera 1

A key to the supraspecific taxa of the Australian Megaloptera, as recognized in this paper, is presented. Identification of species and subspecies is possible by comparison with illustrations of genitalia which are presented for all known forms. Their geographical ranges are quoted. Species status is proposed for phaeoscius Riek and polypastus Riek, both originally described as subspecies of Archichauliodes guttiferus (Walker). A new subgenus of Archichauliodes, Apochauliodes is erected. Stenosialis Tillyard is re‐instated. The adults of the following new taxa are described: Archichauliodes cervulus, A. collifer, A. conversus, A. cuspidatus, A. isolatus, A. lewis, A. neoguttiferus. A. pictus, A. piscator, A. rieki, A. simpsoni, A. uncinatus, Protochauliodes biconicus incertus, P. b. tooloomensis, P. kirramae, Austrosialis maxmouldsi, Stenosialis hollowayi. Also presented is the hitherto undescribed female of Archichauliodes phaeoscius Riek. Austrochauliodes Riek is regarded a junior synonym of Protochauliodes Weele. Archichauliodes australica Kimmins is synonymized with Archichauliodes anagaurus Riek. Five species groups are defined and proposed for the subdivision of Archichauliodes s. str.
