Parasitismo e respostas comportamentais de Acromyrmex coronatus (Fabricius, 1804) e Acromyrmex crassispinus (Forel, 1909) (Hymenoptera: Formicidae) a Myrmosicarius catharinensis Borgmeier, 1928 (Diptera: Phoridae) em Londrina, PR

open access: yesSemina: Ciências Agrárias, 2021
Formigas-cortadeiras do gênero Acromyrmex causam sérios prejuízos em áreas florestais cultivadas. Algumas moscas pertencentes à família Phoridae são conhecidas por parasitá-las e o resultado dessa interação pode fornecer bases promissoras para o manejo ...

Comparative FISH-mapping of TTAGG telomeric sequences to the chromosomes of leafcutter ants (Formicidae, Myrmicinae): is the insect canonical sequence conserved? [PDF]

open access: yesComparative Cytogenetics, 2020
Telomeric sequences are conserved across species. The most common sequence reported among insects is (TTAGG)n, but its universal occurrence is not a consensus because other canonical motifs have been reported.
