“…Studies on sublethal effects of pesticides in terms of alteration in Malpighian tubule cells focused mainly on insects with an economic and/or ecological relevance such as hymenopteran, dipteran and coleopteran species. Ultrastructural, histochemical and immunocytochemical alterations have been investigated only for nicotinoid such as thiamethoxam and imidacloprid in Apis mellifera (De Almeida Rossi et al, ; Catae et al, ), for hydramethylnon (Decio et al, ) and boric acid (Sumida et al, ) in Atta sexdens rubropilosa , for permethrin in Drosophila melanogaster, for fipronil and boric acid in Scaptotrigona postica (Ferreira et al , ). Results from laboratory assay show that the amount and type of alterations in cells of Malpighian tubules depend on the exposure length and the pesticide chemical characteristic, besides the pesticide concentration.…”

Although a number of biomarkers of pollutant exposure have been identified in invertebrate species, little is known about the effect on Malpighian tubules playing an essential role in excretion and osmoregulation. Analyses of structural and functional alterations on this organ can be useful to predict the effects at the organism and population level in monitoring studies of environmental pollution. The aim of the present review is to provide a synthesis of existing knowledge on cellular damages induced by xenobiotics in Malpighian tubules both under laboratory and field conditions. We compared studies of exposure to pesticides and heavy metals as mainly environmental contaminants from anthropogenic activities. This report provided evidence that the exposure to xenobiotics has an effect on this organ and reinforces the need for further research integrating molecular biomarkers with analysis on Malpighian tubules.

“…Thus, after lipid supplementation, C18:2 becomes the main fatty acid in the PPG and hemolymph of A. sexdens rubropilosa workers. Toxicological bioassays conducted with hydramethylnon diluted in soybean oil and A. sexdens rubropilosa (Sumida, 2007;Decio et al, 2013) showed a possible alternative route of ingestion of this active ingredient in the PPGs of leaf-cutting ants with increased pesticide action.…”

The postpharyngeal gland (PPG) in ants has a central role in lipid accumulation. Our objective was to investigate whether the PPG of workers of the leaf-cutting ant Atta sexdens rubropilosa (F.) performs lipid mobilization to the hemolymph, and to verify whether lipids in gland cells are in part oxidized to acetyl-CoA. Increased levels of fatty acids were observed in both the PPG and the hemolymph after 48 h of lipid supplementation. In contrast, after 120 h of lipid supplementation, fatty acid levels were reduced in the PPG and significantly increased in the hemolymph. The gland cells of the PPG of workers supplemented with lipids exhibited a high amount of AcylCoA dehydrogenase, and the lipids were in part β-oxidized to AcetylCoA. These findings suggest that the PPG of A. sexdens rubropilosa workers mobilize fatty acids from their gland cells to the hemolymph. Further work will be needed to elucidate lipid transport from the hemolymph to other organs in this organism.

“…70 This highlights the importance of understanding their structure and physiology. 69,[71][72][73] Different functions of MTs have emerged with the development of postgenomic technologies, mainly in Drosophila, such as microarrays, proteomics, and metabolomics. 74 By means of molecular techniques, Chahine and O'Donnell 75 suggest a coordinated response by the MTs, involving both alterations in detoxification pathways as well as enhanced fluid transport.…”
