“…This association is essential for the fungus to draw the nutrients from the plants that the ants carry into their nests [74]. Natural products can be toxic to the symbiotic fungus Leucoagaricus gongylophorus, as observed for those of R. communis (Euphorbiaceae), Helietta puberula (Rutaceae), Simarouba versicolor (Simaroubaceae) and Canavalia ensiformis (Fabaceae) [76][77][78][79]. Baits with plant extracts were effective in the field as a control measure, stopping ant activity between three and 12 days of application [35].…”

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.

Toxicity of plant extracts from Bahia, Brazil, to Atta sexdens sexdens workers (Hymenoptera: Formicidae)

et al. 2016

Ants of the Atta and Acromyrmex genera (Formicidae: Myrmicinae: Attini) are the true leaf cutting-ants with species of economic importance in America Neotropical and mainly controlled by toxic baits. There are few active ingredients for use in baits, being necessary studies to indicate molecules with insecticide potential. The aim of this study was to evaluate the toxicity of . The contact and ingestion toxicity of all extracts to this ant by was evaluated by topical application and addition in their diet, respectively. Data of contact application were submitted to analysis of variance and Tukey test while those from ingestion were compared by survival curves using the statistical test ¨log rank¨. Through contact, the leaf and branch extracts of Z. rhoifolium and of that of bark of S. amara were the most toxic ones. Through ingestion, four extracts were toxic and showed delayed action. The extract of Z. rhoifolium branches presented the slowest action (S 50 = 10 days). This characteristic is crucial for toxic baits. The Z. rhoifolium leaf and branch extracts were the only ones with contact and ingestion toxicity to A. sexdens sexdens workers.

Toxicity of Substances Isolated from Helietta puberula RE Fr. (Rutaceae) to the Leaf-cutting Ant Atta sexdens L. (Hymenoptera: Formicidae) and the Symbiotic Fungus Leucoagaricus gongylophorus (Singer) Möller

Möller RESUMO -As formigas cortadeiras são pragas que podem causar sérios prejuízos para a agricultura e silvicultura, uma vez que elas possuem o hábito de cortar material vegetal fresco para cultivar o fungo simbionte, sua principal fonte alimentar. Atualmente, métodos químicos têm sido largamente empregados para o controle de formigas cortadeiras e isso tem acarretado sérios problemas à saúde humana, assim como para o meio ambiente e outros organismos não-alvo. Nesse sentido, espécies vegetais são promissoras fontes de novas moléculas inseticidas que podem ser tóxicas tanto para as formigas cortadeiras quanto para o fungo simbionte, além de serem mais degradáveis e menos tóxicas para mamíferos. Em vista disso, o presente estudo objetivou a determinação da toxicidade de extratos, frações e substâncias puras de Helietta puberula RE Fr. (Rutaceae) para operárias médias de Atta sexdens L. (Hymenoptera: Formicidae) e para o seu fungo simbionte, Leucoagaricus gongylophorus (Singer) Möller. A toxicidade para as saúvas foi determinada através de bioensaios por ingestão, enquanto que com o fungo simbionte, foi avaliado o seu desenvolvimento em meio de cultura contendo os extratos vegetais. Os resultados mostraram que dentre as seis substâncias isoladas de H. puberulla, três delas foram concomitantemente tóxicas para as saúvas e para o fungo, mostrando ser essa espécie vegetal uma fonte promissora de novas substâncias para o controle de formigas cortadeiras. PALAVRAS-CHAVE -extratos vegetais, atividade inseticida, atividade fungicida, Rutaceae, controleABSTRACT -Leaf-cutting ants may be a serious pest for the agriculture and silviculture once they cut plant material to cultivate a symbiotic fungus, which is their main food source. Currently, chemical methods are largely used for controlling of these insects, but sometimes with serious damages to human health, environment and other non-target organisms as well. Considering this, some plants are promising as a source of toxic substances, which can be toxic both to leaf-cutting ants and the symbiotic fungus. The main objective of this research was to determine the toxicity of extracts, fractions and isolated substances from Helietta puberula RE Fr. (Rutaceae) to Atta sexdens L. (Hymenoptera: Formicidae) workers and their symbiotic fungus, Leucoagaricus gongylophorus (Singer) Möller. Toxicity of vegetal extracts to leaf-cutting ants were determined by ingestion bioassays, while the activity against the symbiotic fungus was evaluated by its development in a culture medium containing vegetal extracts in it. The results showed that three out of six compounds isolated from H. puberula have effectively targeted both partners simultaneously, indicating that this plant is a promising source of novel insecticidal substances for the control of leaf-cutting ants.
