“…The ENA04 isolate of M. anisopliae was found to be most pathogenic to the A. bisphaerica soldiers, with a TL 50 of 1.15 days, with more than 80% mortality during the first three days of application, and high spore production on ant cadavers [93]. The insecticide imidacloprid, at very low concentrations, applied with B. bassiana, can change ant behavior and increase its susceptibility to this fungus [94].…”

Brazilian forest producers have developed integrated management programs to increase the effectiveness of the control of leaf-cutting ants of the genera Atta and Acromyrmex. These measures reduced the costs and quantity of insecticides used in the plantations. Such integrated management programs are based on monitoring the ant nests, as well as the need and timing of the control methods. Chemical control employing baits is the most commonly used method, however, biological, mechanical and cultural control methods, besides plant resistance, can reduce the quantity of chemicals applied in the plantations.

“…Sublethal contamination with imidacloprid also affected the brain development and motility of callow stingless bee workers (Melipona quadrifasciata anthidioides) [12]. The grooming behaviour of the leafcutting ant Acromyrmex subterraneus subterraneus, which is a defensive action that prevents colony contamination by pathogens, such as the entomopathogenic fungus Beauveria bassiana, was also reduced after exposure to sublethal doses of imidacloprid [13].…”

A neurotoxic pesticide changes the outcome of aggressive interactions between native and invasive ants

et al. 2013

Neurotoxic pesticides, such as neonicotinoids, negatively affect the cognitive capacity and fitness of non-target species, and could also modify interspecific interactions. We tested whether sublethal contamination with neonicotinoid could affect foraging, colony fitness and the outcome of behavioural interactions between a native (Monomorium antarcticum) and an invasive ant species (Linepithema humile). The foraging behaviour of both ants was not affected by neonicotinoid exposure. Colonies of the invasive species exposed to the neonicotinoid produced significantly fewer brood. In interspecific confrontations, individuals of the native species exposed to the neonicotinoid lowered their aggression towards the invasive species, although their survival probability was not affected. Exposed individuals of the invasive species interacting with non-exposed native ants displayed increased aggression and had their survival probability reduced. Nonexposed individuals of the invasive species were less aggressive but more likely to survive when interacting with exposed native ants. These results suggest that non-target exposure of invaders to neonicotinoids could either increase or decrease the probability of survival according to the exposure status of the native species. Given that, in any community, different species have different food preferences, and thus different exposure to pesticides, non-target exposure could potentially change the dynamics of communities and influence invasion success.

“…The association of neurotoxic insecticide and pathogen also seems promising, as recently suggested. 4,33,34 This is plausible because the former can impair the ants' naturally protective behaviour against pathogen contamination, which is the alleged cause of the little success so far obtained with entomopathogen use against leaf-cutting ants, despite the high laboratory efficacy of the tactic. 4,35,36 Thus, the findings reported here suggest alternative venues in pursuing management of leaf-cutting ants in forest plantations that are consistent with current demands of certification agencies and product marketability.…”
