“…There was an increase in smaller dung beetle species abundance with less biomass. Herbicides are applied in all GM maize crops, as well as most of the conventional maize crops, and herbicide application can cause a decline in the majority of dung beetles and impair reproductive function [ 79 ]. Forest-dependent dung beetle species depend in part on their ability to survive in human-modified landscapes [ 80 ].…”

Dung beetle community structures changes due to the effects of destruction, fragmentation, isolation and decrease in tropical forest area, and therefore are considered ecological indicators. In order to assess the influence of type of maize cultivated and associated maize management on dung beetle communities in Atlantic Forest fragments surrounded by conventional and transgenic maize were evaluated 40 Atlantic Forest fragments of different sizes, 20 surrounded by GM maize and 20 surrounded by conventional maize, in February 2013 and 2014 in Southern Brazil. After applying a sampling protocol in each fragment (10 pitfall traps baited with human feces or carrion exposed for 48 h), a total of 3454 individuals from 44 species were captured: 1142 individuals from 38 species in GM maize surrounded fragments, and 2312 from 42 species in conventional maize surrounded fragments. Differences in dung beetle communities were found between GM and conventional maize communities. As expected for fragmented areas, the covariance analysis showed a greater species richness in larger fragments under both conditions; however species richness was greater in fragments surrounded by conventional maize. Dung beetle structure in the forest fragments was explained by environmental variables, fragment area, spatial distance and also type of maize (transgenic or conventional) associated with maize management techniques. In Southern Brazil’s scenario, the use of GM maize combined with associated agricultural management may be accelerating the loss of diversity in Atlantic Forest areas, and consequently, important ecosystem services provided by dung beetles may be lost.

“…The honey bee, Apis mellifera L. (Hymenoptera: Apidae) colonies fed 2,4-D experienced reduced brood production at a concentration of 100 ppm, and eggs failed to hatch when the colony was exposed to 1000 ppm [24]. Martinez et al [25] correlated the population declines in three dung beetles with the use of a 2,4-D commercial formulation. Furthermore, commercial formulations of 2,4-D has been reported to be highly toxic, increase development time and decrease male population in larvae of lady beetle, Coleomegilla maculata DeGeer (Coleoptera: Coccinellidae) [14].…”

Exposure of the African mound building termite, Macrotermes bellicosus workers to commercially formulated 2,4-D and atrazine caused high mortality and impaired locomotor response

Recent empirical evidence suggests that herbicides have damaging effects on non-target organisms in both natural and semi-natural ecosystems. The African mound building termite, Macrotermes bellicosus, is an important beneficial insect that functions as an ecosystem engineer due to its role in the breakdown of dead and decaying materials. Here, we examined the effects of 2,4-D amine salt (2,4-D) and atrazine based herbicides viz. Vestamine ® and Ultrazine ® on the survival and locomotion response of M. bellicosus. Worker termites were treated with a range of concentrations of Vestamine ® (the recommended concentration: 6.25 ml per 500 ml of water, 0.25-and 0.5-fold below the recommended concentration and distilled water as control) and Ultrazine ® (the recommended concentration: 3.75 ml per 500 ml of water, 0.25-, 0.5-, 2.0-and 4-fold of the recommended concentration and distilled water as control) for 24 hours for the mortality test, and allowed to run for 15 seconds for the locomotion trial. All concentrations of both Vestamine ® and Ultrazine ® were highly toxic to worker termites and mortality increased as the concentration and time after treatment increased. For both herbicides, concentrations far less than the recommended rates caused 100% mortality. The speed of termites was significantly influenced by both Vestamine ® and Ultrazine ® as termites exposed to all tested concentrations of the herbicides exhibited reduced running speed than the control. These findings suggest that beneficial insects, especially M. bellicosus may experience high mortality (up to 100%) and reduced mobility if they are sprayed upon or come in contact with plant materials that have been freshly sprayed with (less or more than) the recommended concentrations of Vestamine ® and Ultrazine ®. The findings of our study calls for the reassessment of the usage of 2,4-D and atrazine based herbicides in weed control in termite and other beneficial insect populated habitats.

“…Two or more successive treatments at three weekly intervals had the potential to drive beetle populations towards local extinction unless there is significant immigration from surrounding untreated areas [115]. A similar situation was described in Mexico with a herbicide widely used to control weeds in pastures, which drove local dung beetle populations towards extinction (due to drastic reduction in female fecundity) when the herbicide was applied during the beetle breeding period [77]. Forbes [30] reasoned that, at any one time in the field, only a small proportion of dung pats would contain residues of ivermectin, hence beetles can easily move to an untreated pat.…”

-The overall purpose of this paper was to review the major and most recent literature relating the effects of anthelmintics on dung breeding invertebrates and dung degradation. Faecal residues or metabolites of drugs belonging to the benzimidazole and levamisole/morantel groups are relatively harmless to dung fauna, on the contrary to other anthelmintics such as coumaphos, dichlorvos, phenothiazine, piperazine, synthetic pyrethroids, and most macrocyclic lactones which have been shown to be highly toxic for dung beetles (abamectin, ivermectin, eprinomectin, doramectin), among which moxidectin was the less toxic for dung beetles. To date, the detrimental impact upon non-target organisms has been considered acceptable in eradicating the parasites because of their economic importance to commercial livestock production. The consequences of routine treatments are discussed with consideration of the long-term consequences for cow pat fauna and sustainable pastureland ecology.anthelmintic / residue / dung beetle / Diptera / sustainable parasite control Résumé -Usage des anthelminthiques en élevage et évaluation des risques pour la faune non cible du pâturage. Cet article de synthèse passe en revue les travaux de la littérature les plus récents concernant les effets secondaires des principaux produits vétérinaires utilisés en routine sur la faune coprophage et sur la dégradation des excréments dans les pâturages. Les résidus (ou les métabolites) des groupes du benzimidazole et levamisole/morantel trouvés dans les excréments s'avèrent relativement peu toxiques pour la faune coprophage. Au contraire les anthelminthiques des groupes suivants s'avèrent hautement toxiques: coumaphos, dichlorvos, phénothiazine, pipérazine, pyréthroïdes de synthèse, et la plupart des lactones macrocycliques (abamectine, ivermectine, éprinomectine, doramectine), la moxidectine étant la moins toxique pour la faune coprophage. Jusqu'à présent, cet impact négatif a été considéré comme acceptable par les éleveurs et firmes pharmaceutiques en regard de l'importance économique du contrôle et/ou l'éradication des parasites. Les conséquences des traitements de routine sont discutées en considérant que l'absence de dégradation des bouses constatée 547
