Coleoborers in Bambusa sp. in the Southern Amazon

Abstract

Bamboo (Bambusa sp.) is a grass species with high potential for exploitation, however, this raw material is easily attacked by xylophagous agents such as Coleoptera. The objective of this study is thus to analyse the presence of wood-boring beetles associated with Bambusa sp. in Alta Floresta, Mato Grosso, Brazil. The study was carried out in a bamboo plantation, from August 2016 to July 2017. Two models of ethanolic traps were used, PET Santa Maria and ESALQ-84. Three families of wood-boring beetles were observed in this study: Bostrichidae, Cerambycidae and Curculionidae. 2,144 individuals were identified, belonging to 19 species, in four subfamilies and 11 tribes, and the species Xyleborus affinis was the most frequently collected. Thus, this study constitutes an important contribution to the knowledge of coleoborers associated with bamboo plantations, with the registration of the occurrence of species, as well as contributing to the knowledge of the entomofauna associated with species cultivated in the Southern Amazon.

Tropisetron improved testicular inflammation in the streptozotocin‐induced diabetic rats: The role of toll‐like receptor 4 (TLR4) and mir146a

“…The overproduction of ROS and the release of inflammatory cytokines develop apoptosis. [ 42 ] In this process, the activation of caspase‐3 indicates the final step of the apoptosis pathway; hence, itis a reliable hallmark of apoptosis. [ 43 ] The present findings illustrated that the caspase3 expression decreased after tropisetron treatment in the testes of diabetic rats.…”

Increased capture efficiency of Scolytinae with modified semi-funnel trap model

“…Scolytinae species, in high populations, are pests and can damage trees reducing wood production and increasing fire risks (Li and Li, 2019). Besides, Scolytinae can be vectors of phytopathogenic fungi (Chakraborty et al, 2020;Contarini et al, 2020) causing tree death and some species can transmit viruses (Oliveira et al, 2021). These beetles identify suitable host plants for colonization by detecting semiochemicals released by those physiologically stressed (Özcan et al, 2018;Zhao et al, 2020) or recently dead or dying (Aflitto et al, 2015).…”
