Abstract: Amblyomma Koch, 1844 is distributed worldwide, with ca. 130 species currently recognized. These ticks are vectors of pathogens to animals and humans, including the causative agent of the New World Rocky Mountain spotted fever. Species of the Amblyomma parasitize a wide range of organisms, especially medium and large terrestrial mammals. Here we report for the first time the association of Myotis lavali Moratelli, Peracchi, Dias & Oliveira, 2011, Noctilio albiventris Desmarest, 1818 and Noctilio leporinus (Linnaeus, 1758) as hosts for Amblyomma sculptum Berlese, 1888. The ticks were originally identified as Amblyomma cajennense (Fabricius, 1787), in 2011. However, a later taxonomic review indicated that the species of the A. cajennense complex occurring in the Caatinga is A. sculptum. We also discuss the ecoepidemiological implications of this association.

Is the spider a good biological control agent for Plutella xylostella (Lepidoptera: Plutellidae)? https://zoologia.pensoft.net/article/23481/ Zoologia 35: 1-8

Abstract: Spiders, as predators of insects and other invertebrates, are an important part of the natural enemies, and they are recognized as an important biological control agent. Plutella xylostella (Linnaeus, 1758), the diamondback moth (DBM), is a well-known and destructive insect pest of brassicaceous crops worldwide. Here, we analyzed the functional responses of four spiders (Araneae) – Ebrechtella tricuspidata (Fabricius, 1775) (Thomisidae), Pardosa laura (Karsch, 1879) (Lycosidae), Pardosa astrigera (Koch, 1878) (Lycosidae), and Pardosa pseudoannulata (Bösenberg & Strand, 1906) (Lycosidae) – on P. xylostella larvae. We also analyzed intraspecific disturbances in the predation reaction and the intensity of scrambling competition of the spiders to P. xylostella larvae. Our results demonstrated that the functional responses of four spiders of different genera were in line with the Holling II model. Two Lycosidae spiders (P. astrigera and P. pseudoannulata) had the potential to control P. xylostella, and female and male spiders that belonged to the same species had different functional responses to P. xylostella. The functional responses of female predation of P. astrigena, P. laura, and P. pseudoannulata was stronger than the males, but male E. tricuspidatus had stronger functional responses to predation than females. We used the Hassell model to describe the intraspecific disturbance experiments of four spiders. There were intraspecific disturbances in the predation reactions of spiders, indicating that the predation ratio of spiders decreased in relation to the increase of its density, and with the increase of spider density, the intensity of scrambling competition of the spider increased.
