بهمنظور شناسایی پارازیتوییدهای سفیدهی کوچک کلم، Pieris rapae (Linnaeus, 1758) (Lepidoptera: Pieridae) از مزارع کلمگل در جنوب تهران، در سال 1390 نمونهبرداری صورت گرفت. در بین نمونهها گونهی Hyposoter clausus (Brischke, 1880)(Hymenoptera: Ichneumonidae) برای اولینبار از از روی سفیدهی کوچک کلم و منطقهی تهران گزارش میشود. گونهی دیگر بهنام Cotesia glomerata L. (Hymenoptera: Braconidae) نی...
A new solitary endoparasitoid of the larva of Bazariaturensis Ragonot, 1887 (Lepidoptera, Pyralidae) in Qinghai province, China, Campoplexbazariae Sheng, sp. n., belonging to the subfamily Campopleginae (Hymenoptera, Ichneumonidae), is reported. Illustrations of the new species are provided.
The new species Arcoptilia naumanni sp. nov. (Lepidoptera, Pterophoridae) is described and illustrated from males found in Angola. Platyptilia rufamaculata Gielis, 2011, syn. nov. is established as a junior synonym of Arcoptilia pongola Ustjuzhanin & Kovtunovich, 2010.
The importance of trans-generational effects in shaping an individuals' phenotype and fitness, and consequently even impacting population dynamics is increasingly apparent. Most of the research on trans-generational effects still focuses on plants, mammals, and birds. In the past few years, however, increasing number of studies, especially on maternal effects, have highlighted their importance ...
This study reports DNA barcodes for more than 1300 Lepidoptera species from the eastern half of North America, establishing that 99.3 per cent of these species possess diagnostic barcode sequences. Intraspecific divergences averaged just 0.43 per cent among this assemblage, but most values were lower. The mean was elevated by deep barcode divergences (greater than 2%) in 5.1 per cent of the spe...
The control of Lepidoptera pests should be carried out before hatching of their caterpillars to avoid damage to the crops. The aim of this work was to assess the activity of neem (trade name: Natuneem, producer: Base Fértil, Chapadão do Sul, Brazil) and pyroligneous extracts (trade name: Biopirol 7M, producer: Biocarbo, Itabirito, Brazil) at 10 mL/L (1%) and 20 mL/L (2%) contents on egg masses ...
Transfer of DNA sequences between species regardless of their evolutionary distance is very common in bacteria, but evidence that horizontal gene transfer (HGT) also occurs in multicellular organisms has been accumulating in the past few years. The actual extent of this phenomenon is underestimated due to frequent sequence filtering of "alien" DNA before genome assembly. However, recent studies...
We reviewed the theory of conservation genetics, with special emphasis on the influence of haplodiploidy and other aspects of bee biology upon conservation genetic parameters. We then investigated the possibility that pollinator decline can be addressed in this way, using two meta-analytical approaches on genetic data from the Hymenoptera and the Lepidoptera. First, we compared levels of hetero...
Trichogramma pretiosum Riley and Trichogrammatoidea annulata De Santis are commonly found in avocado and persimmon orchards in northern Parana state. However, their abundance depends on whether insecticides are used or not to control the key lepidopteran pests Stenoma catenifer (Wals.) (Lepidoptera: Elachistidae) and Hypocala andremona (Stoll) (Lepidoptera: Noctuidae), respectively. The aim of ...
Lepidoptera (butterflies and moths), as many other groups of animals and plants, simultaneously represent preservation of ancestral karyotype in the majority of families with a high degree of chromosome number instability in numerous independently evolved phylogenetic lineages. However, the pattern and trends of karyotype evolution in some Lepidoptera families are poorly studied. Here I provide...
