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.
Highlights
The expansion and evolution of Integrated Pest Management programs have required the refinement of techniques for insect rearing in order to implement new technologies for pest control, such as biological control with predators and parasitoids (Cônsoli and Parra, 1997)
The life cycle of Abaris basistriata reared on different substrates
The biological cycle duration of A. basistriata (35.8-38.5 days) was higher than that reported for some other species of carabid beetles present in Brazilian agro‐ecosystems (Pegoraro and Foerster, 1985; Correa‐Ferreira and Pollato, 1989)
Summary
The expansion and evolution of Integrated Pest Management programs have required the refinement of techniques for insect rearing in order to implement new technologies for pest control, such as biological control with predators and parasitoids (Cônsoli and Parra, 1997). It can permit the introduction of individuals in the field for biological control (Symondson et al, 2002). 457-463 capacity, feeding habits, voracity, and predatory potential if they are to be used as agents of agricultural pests (Suenaga and Hamamura, 1998; Snyder and Ives, 2001; Fawki and Toft, 2005; Saska, 2008) Biol., 2018 , vol 78, no. 3, pp. 457-463 capacity, feeding habits, voracity, and predatory potential if they are to be used as agents of agricultural pests (Suenaga and Hamamura, 1998; Snyder and Ives, 2001; Fawki and Toft, 2005; Saska, 2008)
