Abstract: We present hereafter a protocol to test attractiveness of new formulations of granulated baits used against leaf-cutting ants (Acromyrmex spp. and Atta spp.) in the field. Its purpose is to standardize the methodology, thus making possible further comparison of results wherever these tests are carried out.

“…They may be involved in both chemical and mechanical defense, negatively affecting the oviposition rate and feeding of herbivorous insects and nutrition of larvae (Lokesh and Singh 2005). It is possible that the leaf trichome density in the studied species can play a role in protection against herbivores insects, which are considered pests in the cultivation of some species of this genus, such as beetle (Barbosa and Fonseca 2002), caterpillar (Lourido et al 2007), and leaf-cutting ants (Delabie 1989). However, additional studies are needed to better understand the ecological role of these trichomes in Theobroma.…”

“…Another problem is the activity of the colonies prior to experimentation (rearing stage), because according to Delabie et al (2000), it is important to make sure that nests used in experiments of attractiveness are active. These should have good transport of leaves and large size workers (head width greater than 2 mm).…”

“…4,9,28 Ten colonies of this species were field collected in Viçosa County, state of Minas Gerais, Brazil (20 ∘ 45 ′ 14 ′′ S, 42 ∘ 52 ′ 54 ′′ W), and established in the laboratory where they were maintained under controlled conditions of 25 ± 5 ∘ C temperature, 75 ± 5% relative humidity and 12 h scotophase, as described elsewhere. 29 Each colony produced about 1 L of fungus and exhibited similar foraging activity; all of the colonies were monogynic, exhibiting progeny at each of the developmental stages (i.e.…”
