The life cycle of Neotropical ground beetle, Abaris basistriata (Coleoptera: Carabidae) reared on different substrates

Abstract

Carabids are recognized worldwide as biological control agents of agricultural pests. The objective was to compare the life cycle of Abaris basistriata Chaudoir (Coleoptera: Carabidae) on three substrates: soil, fine vermiculite, or paper napkins. The biological cycle of A. basistriata presented different durations in soil and paper. The viability of eggs and larvae survival of the first and second instars were similar on all three substrates, while the third instar and pupa in the soil presented higher survival when compared with vermiculite and paper. The soil substrate was more favorable for the longevity of the carabid beetle. Abaris basistriata showed a shorter pre-oviposition period and a higher oviposition and post-oviposition period in the soil. Fecundity and fertility were higher when A. basistriata was reared on soil. The soil was most favorable substrate for rearing of A. basistriata in the laboratory. This information may make this species useful for the biological control.Keywords: biological cycle, biological control, laboratory rearing, predation, prey.

Egg characterization and laying pattern of Oncideres saga (Coleoptera: Cerambycidae) in Inga edulis (Fabaceae)

“…The egg laying choices by insects affect the number of eggs deposited (Minkenberg et al, 1992;Barbosa-Andrade et al, 2018) and their specializations, throughout evolution, determine the egg morphology (Forister et al, 2006;Church et al, 2019). Understand the laying pattern is fundamental for integrated pest management programs (Shaw et al, 2018) and the egg morphology for taxonomy (Suman et al, 2011).…”
