Contamination Route of Leaf-Cutting Worker Ants Analyzed Through a Fat-Soluble Tracer Dye in Toxic Bait
(Entomological Soc Brasil, 2019-04-01)
Our study seeks to discover contamination routes of leaf-cutting worker ants during chemical control by formicide baits. To do so, toxic baits containing fat-soluble tracer dye were provided to colonies of three subspecies ...
Chemical control of leaf-cutting ants: how do workers disperse toxic bait fragments onto fungus garden?
(Soc Brasileira Entomologia, 2019-10-01)
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 ...
Control of Linepithema micans (Hymenoptera: Formicidae) and Eurhizococcus brasiliensis (Hemiptera: Margarodidae) in Vineyards Using Toxic Baits
(Oxford Univ Press Inc, 2016-08-01)
Linepithema micans (Forel) (Hymenoptera: Formicidae) is the main ant species responsible for dispersal of Eurhizococcus brasiliensis (Wille) (Hemiptera: Margarodidae), a root scale that damages grapevines in southern Brazil. ...
Effects of diafenthiuron in toxic baits on colonies of leaf-cutting ants (Hymenoptera: Formicidae)
(2017-09-01)
Dianfenthiuron is a pre-insecticide that can be activated by photolysis, and may be a promising formicide. This study evaluated the effect of diafenthiuron after photolysis in colonies of Atta sexdens rubropilosa Forel, ...
Mechanism of leaf‐cutting ant colony suppression by fipronil used in attractive toxic baits

DISTRIBUIÇÃO DE SUBSTRATOS NAS COLÔNIAS DE Atta laevigata (F. Smith, 1858) (HYMENOPTERA: FORMICIDAE)
(Universidade de São Paulo (USP), Escola Superior de Agricultura Luiz de Queiroz (ESALQ), 1999-01-01)
Estudou-se a distribuição de substratos em duas colônias adultas (L-1 e L-2) da saúva Atta laevigata (F. Smith, 1858), com áreas de terra solta de 26,10 e 31,30 m2. Alguns orifícios de abastecimento foram mapeados utilizando-se ...
Laboratory Assessment of two Active Ingredients for Control of Coptotermes gestroi (Isoptera: Rhinotermitidae)
(California State University, 2009-01-01)
The subterranean termite Coptotermes gestroi Wasmann (Isoptera: Rhinotermitidae) is a pest of major economic importance in urban environments of southeastern Brazil. Compared to using pesticides for termite control, termite ...
Foraging Behavior and Mortality of Ectatomma brunneum (Hymenoptera, Formicidae) in Simultaneous Exposure to Ant Baits and Conventional Diet in Laboratory
(California State University, 2010-01-01)
The objective of this work was to identify whether the presence of leaf-cutting ant baits in the foraging arena of the ant Ectatomma brunneum (Smith) affects its foraging behavior or causes mortality in laboratory. A ...
