Polyandry, i.e. females mating with multiple males, is more common than previously anticipated and potentially provides both direct and indirect fitness benefits to females. The level of polyandry (defined by the lifetime number of male mates of a female) is an important determinant of the occurrence and intensity of sexual selection acting on male phenotypes. While the forces of sexual selecti...

We report here the full mitochondrial genome sequence of Limonius californicus, a species of click beetle that is an agricultural pest in its larval form. The circular genome is 16.5 kb and contains 13 protein-coding genes, 2 rRNA genes, and 22 tRNA genes.

During a survey of the flat mites (Tenuipalpidae) on forest trees and agricultural crops in five different sites Apulian territories (Southern Italy) 2019, Brevipalpus recki (Livschitz Mitrofanov) Cenopalpus longirostris were collected Quercus pubescens (Willdenow) (Fagaceae). The authors give an account new record C. longirostris, which was not listed previous Italian fauna, finding B. souther...

Eleven microsatellite loci were isolated and characterized for the intertidal copepod Tigriopus californicus . Primers reliably amplify alleles in inbred lines derived from two divergent populations previously shown to have genetic distances of 18% for the mitochondrial cytochrome oxidase I gene. The 11 loci provided markers for eight of the species’ 12 chromosomes.

Biological control can be severely disrupted by hot and dry environmental conditions associated with climate change. These may alter the food web configuration of arthropod communities through their effects on species interactions. They could disrupt competition between phytoseiid predators Euseius stipulatus, Neoseiulus californicus, Phytoseiulus persimilis, which are key natural enemies Tetra...

Behaviors of Eretmocerus sp. nr. californicus females attacking Bemisia argentifolii Bellows & Perring infesting cotton, Gossypium hirsutum L., and melon, Cucumis melo L., were quantified. Adult female behaviors were described and quantified for Eret. sp. nr. californicus to establish a behavioral time budget analysis. Females readily searched for host whitefly nymphs on cotton leaves with walk...

Animals are commonly exposed to multiple environmental stimuli, but whether, and under which circumstances, they can attend to multiple stimuli in multitask learning challenges is elusive. Here, we assessed whether simultaneously occurring chemosensory stimuli interfere with each other in a dual-task learning challenge. We exposed predatory mites Neoseiulus californicus early in life to either ...
