Última Chemical control of leaf-cutting ants: how do workers disperse toxic bait fragments onto fungus garden? Rev. Bras. entomol. Catalani,Gabriela C.; Sousa,Kátia K.A.; Camargo,Roberto S. da; Caldato,Nadia; Matos,Carlos A.O.; Forti,Luiz C.. ABSTRACT Leaf-cutting ants are controlled with toxic baits. For the method’s greater efficiency, the baits must be distributed and processed by workers during fungus cultivation. To test hypotheses whether the mode of action of the active ingredients, which blocks the sodium channels and interrupts the production of ATP in the mitochondria, interferes with fragment distribution in nests; the dispersion of pellets fragments during fungus cultivation by workers was assessed, spatially referencing the fragment onto the fungus garden. Pellets fragments were randomly distributed, but the amount pellets fragments was influenced by the way that the active ingredient acts in the colony.

Bras. entomol. Caldato,Nadia; Forti,Luiz Carlos; Camargo,Roberto da Silva; Lopes,Juliane Floriano Santos; Fourcassié,Vincent. ABSTRACT Dynamics of the restoration of physical trails in the grass-cutting ant Atta capiguara. Leaf-cutting ants of the genus Atta build long physical trails by cutting the vegetation growing on the soil surface and removing the small objects they find across their path. Little is known on the dynamics of trail construction in these ants. How much time do they need to build a trail? To answer this question we selected six trails belonging to two different nests of A. capiguara and removed on each trail a block of soil of 20 cm × 15 cm that included a portion of the physical trail. This block was then replaced by a new block of the same size that was removed in the pasture near the trail and that was uniformly covered by the same type of vegetation as...

Sousa,Kátia Kaelly Andrade; Camargo,Roberto da Silva; Forti,Luiz Carlos; Caldato,Nadia. ABSTRACT Leaf-cutting ants live symbiotically with a fungus that they cultivate on the plant leaves that they cut. The innumerous studies on the plant selection mechanism used by leaf-cutting ants show the researchers’ interest in this issue. Many classical studies propose that plants are selected according to the fungus garden nutritional needs and the absence of potentially harmful substances. This hypothesis is corroborated by behavioral experiments using cycloheximide (fungicide) with citric pulp or forage plants greatly accepted by leaf-cutting ants. According to this hypothesis, under the action of a fungicide, the fungus emits an allomone that informs worker ants that some food is inadequate to its growth. Although some authors state that the... Tipo: Info:eu-repo/semantics/other Palavras-chave: Leaf-cutting ants; Cycloheximide; Mortality; Formicide screening.

Forti,Luiz Carlos; Moreira,Aldenise Alves; Camargo,Roberto da Silva; Caldato,Nadia; Castellani,Maria Aparecida. ABSTRACT Atta bisphaerica is a species of grass-cutting ants commonly found in the Cerrado biome. The Brazilian Cerrado (savanna) biome covers 2 million km representing 23% of the area of the country. It is an ancient biome with rich biodiversity, estimated at 160,000 species of plants, fungi and animals. However, little is known about their nest architecture development. This study investigated the architecture of fourteen A. bisphaerica nests from Botucatu, São Paulo, Brazil. Molds were made of the nests by filling them with cement to allow better visualization of internal structures such as chambers and tunnels. After excavation, the depth and dimensions (length, width, and height) of the chambers were measured. As expected, there was a lateral...
