Studies on the Species Complex Hexomyza sarothamni (Hendel, 1923) and Hexomyza kiefferi (Tavares, 1902) comb. nov. (Diptera: Agromyzidae) in Spain
2012
The parasitoid species complex associated with sexual and parthenogenetic Naryciinae (Lepidoptera: Psychidae): Integrating ecological and molecular a…
2011
This study describes the parasitoid species complex associated with seven closely related species of sexual (Siederia rupi- collella, S. listerella, Dahlica lazuri, D. charlottae and D. lichenella) and parthenogenetic (Dahlica fennicella and D. triquetrella) Naryciinae (Lepidoptera: Psychidae) in Central Finland. A thorough ecological analysis of all the species of parasitoids recorded was combined with analyses of molecular data. Mitochondrial and nuclear DNA data were obtained from all the species in order to (1) detect cryptic species associated with host specialization, (2) assign undescribed males to females, and (3) verify the morphological identification of closely related species. A…
Pathogenicity of intrathoracically administrated Bacillus thuringiensis spores in Blatta orientalis.
2006
Abstract The ability of Bacillus thuringiensis to produce septicaemia in Periplaneta americana and Blatta orientalis has been investigated. Spores and crystals from several wild-type strains as well as spores of a B. thuringiensis crystal-deficient mutant, were first orally administrated at high doses, and no significant mortality was recorded. Intrathoracic injection of spore suspensions in P. americana revealed that this species is not very susceptible to B. thuringiensis spores. B. orientalis , by contrast, was found to be very susceptible to B. thuringiensis , with a LD 50 of about 35,000 spores, that is similar to that reported on Lepidoptera challenged with parenterally injected B. th…
The enigmatic case of the genus Argyresthia in the Azores Islands (Lepidoptera Argyresthiidae)
2020
The species composition of the genus Argyresthia Hübner, 1825 in the Azores is examined. Argyresthia brumella, sp. nov., is described and illustrated from Terceira and Flores Islands. Argyresthia minusculella Rebel, 1940, syn. nov. and Tinea poecilella Rebel, 1940, syn. nov. are synonymized with Argyresthia atlanticella Rebel, 1940. The high variability of A. atlanticella is revealed through the polymorphic wing pattern and the intraspecific genetic divergence of the DNA barcode COI in the specimens examined.
<p><strong>Revision of the plant bug genus <em>Cylapocoris</em> Carvalho (Hemiptera: Heteroptera: Miridae: Cylapinae), with d…
2013
The plant bug genus Cylapocoris Carvalho, 1954 is revised. Seven new species: Cylapocoris costaricaensis sp. nov., C. cucullatus sp. nov., C. fulvus sp. nov., C. laevigatus sp. nov., C. marmoreus sp. nov., C. plectipennis sp. nov., and C. simplex sp. nov. are described from Costa Rica, Brazil, Ecuador, and Venezuela. The genus Adcylapocoris Carvalho, 1989 is synonymized with Cylapocoris . Five species: C. castaneus (Carvalho, 1989), C. funebris (Distant, 1883), C. pilosus Carvalho, 1954 , C. sulinus Carvalho & Gomes 1971 , and C. tiquiensis Carvalho, 1954 are redescribed. Illustrations of the male genitalia, color pho-tographs of dorsal and lateral views of the adult of most species, scanni…
PENIS MORPHOLOGY IN ONCOPODIDAE (OPILIONES, LANIATORES): EVOLUTIONARY TRENDS AND RELATIONSHIPS
2002
Abstract An interim report on our ongoing revisional study is given together with a short summary of the current knowledge on the systematics and distribution of the family Oncopodidae (Opiliones, Laniatores). An exceptionally high diversity in male genitalia is shown and its possible evolution is discussed. Four major penis types are distinguished in the Oncopodidae and compared with similar forms in other laniatorean families.
A new species of Hedya Hübner from Iran with proposed rearrangement of some species currently assigned to Metendothenia Diakonoff (Lepidoptera: Tortr…
2011
Hedya tritofa, new species, is described and illustrated based on eleven males and five females collected in northern Iran (Gilan, Mazandaran, and Golestan provinces). Morphology and diagnostic characters of Hedya Hubner, 1825, Metendothenia Diakonoff, 1973, the Olethreutes group of genera, and the Neopotamia group of genera are discussed. We propose the resurrection of the combinations Hedya atropunctana (Zetterstedt, 1840), revised status, and H. separatana (Kearfott, 1907), revised status, and the new combination H. inouei (Kawabe, 1987).
Description Of A New Species Of Aspinipogon Razowski And Becker, 2010, With The First Reported Female Of The Genus (Lepidoptera: Tortricidae)
2020
AspinipogonRazowski and Becker, 2010 was described as a monotypic genus from Brazil. Aspinipogon samaypatensis Perez Santa-Rita, Valdivia and Baixeras, new species, is described and illustrated from Bolivia. The female of Aspinipogon is reported for the first time, completing the description of the genus. The unusual combination of characters (e.g., wing pattern and venation, male and female genitalia) are discussed in the context of the enigmatic systematic position of Aspinipogon.
Effects of the ingestion ofSerratula tinctoria extracts, a plant containing phytoecdysteroids, on the development of the vineyard pestLobesia botrana…
1997
We describe here the effects of extracts from Serratula tinctoria, a plant producing phytoecdysteroids, on the growth and development of Lobesia botrana, an economically important pest in vineyards. Leaves, hairy roots, or semi-purified (by Sep-Pak procedure) methanolic extracts from this plant were incorporated into an artificial diet given to insects. Larval growth, mortality, weight, and sex-ratio were investigated, as well as sterol and ecdysteroid contents. Experimental diets induced an important mortality in the first, second, and third larval instars, but also in pupae. As males appeared more sensitive to extracts, sex ratio was significantly modified on experimental diets (particula…
Dichrorampha dinarica, new species, a century of confusion in European lepidopterology (Lepidoptera: Tortricidae) resolved by combining morphology an…
2012
Dichrorampha dinarica, new species, is described from the Dinaric mountains (Macedonia, Bosnia and Herzegovina). The newspecies was formerly confused with D. ligulana (Herrich-Schäffer, 1851) from the Alps and D. rilana Drenowsky, 1909 fromthe Rila mountains (Bulgaria). Therefore, a re-description of D. rilana is provided based on topotypical specimens. The diag-nostic morphological characters of the involved species, supported by significant divergence of the mtDNA barcode (COI fragment of 658 bp), are discussed in detail.
