We report the occurrence of natural enemies of Plutella xylostela (L.) in organically farmed kale in Pernambuco, Brazil. Seven natural enemies were observed parasitizing or preying on larvae and pupae of P. xylostella--three parasitoids: Cotesia plutellae Kurdjumov (Hym.: Braconidae), Conura pseudofulvovariegata (Becker) (Hym.: Chalcididae) and Tetrastichus howardi (Olliff) (Hym.: Eulophidae), ...

A new fossil species of salticid spider (Araneae: Salticidae) is described based on an amber-embedded specimen. The specimen was collected from lignite-sandstone early-mid Miocene sediments near the town of Totolapa in Chiapas, southwestern Mexico. The diagnosis and description is supported by key characters that best match the genus Maevia Koch, 1846. Thus, this new fossil species has been nam...

In this paper we revise the species of Sicarius (Araneae: Sicariidae) from the Brazilian Caatinga, the largest tropical dry forest nucleus in the world. We redescribe, designate a neotype and provide new records for Sicarius tropicus (Mello- Leitão, 1936), the only species previously known from the region, and describe three new species: S. cariri n. sp., S. diadorim n. sp. and S. ornatus n. sp...

A fossil tarantula (Araneae: Mygalomorphae: Theraphosidae) is described from an exuvium in Tertiary (Miocene) Chiapas amber, Simojovel region, Chiapas State, Mexico. It is difficult to assign it further taxonomically, but it is the first mygalomorph recorded from Chiapas amber and only the second unequivocal record of a fossil theraphosid. With a carapace length of ca. 0.9 cm and an estimated l...

We present the first record of Holothele longipes (L. Koch, 1875) (Araneae, Theraphosidae) from Republic Ecuador, based on a male specimen collected near Puerto Misahuallí, province Napo, in north-eastern foothills Andes, upper River Napo basin. This new extends geographic range H. by approximately 554 km west nearest previously known locality, Momón, department Loreto, Pe...

Soil arthropods are an essential part of ecosystem contributing significantly to maintaining biodiversity and functioning. The present study was conducted investigate the diversity abundance soil in selected habitats Jahangirnagar University campus, Savar, Dhaka, Bangladesh. Sampling at three different habitats, viz., woodland (W), grassland with herbs (GH), (WH), from February 2022 July using ...

New faunistic data are provided on the ground spiders (Araneae: Gnaphosidae) of Iraq. Three genera ( Haplodrassus Chamberlin, 1922; Minosiella Dalmas, 1921; Odontodrassus Jézéquel, 1965) and six species dalmatensis (L. Koch, 1866); intermedia Denis, 1958; aravaensis Levy, 1999; mundulus (O. Pickard-Cambridge, 1872); Pterotricha dalmasi Fage, 1929; Zelotes fagei 1955) reported in Iraq for first ...

Arthropods compose a large proportion of biological diversity and play important ecological roles as decomposers, pollinators, predators, prey, and nutrient cyclers. We sampled ground-occurring macroarthropods in intact gaps created by wind disturbance, in salvage-logged gaps, and in closed canopy mature forest (controls) during June 199%May 1999 using drift fences with pitfall traps. Basal are...
