“…Arthropods, such as Edaphic collembola, were also studied to verify the effect of contact with nicosulfuron (Bretaud et al, 2000;Lins et al, 2007); arthropod populations declined and there were changes in the activity and molecular forms of acetylcholinesterase. Fermino et al (2010) also used CECs to study the nuclear activity of Malpighian tubules of D. saccharalis, which are divided into 3 regions: proximal, middle, and distal; differences in the CECs between the regions were identified.…”

ABSTRACT. The sugarcane borer Diatraea saccharalis is widely known as the main pest of sugarcane crop, causing increased damage to the entire fields. Measures to control this pest involve the use of chemicals and biological control with Cotesia flavipes wasps. In this study, we evaluated the insecticides fipronil (Frontline; 0.0025%), malathion (Malatol Bio Carb; 0.4%), cipermetrina (Galgotrin; 10%), and neem oil (Natuneem; 100%) and the herbicide nicosulfuron (Sanson 40 SC; 100%) in the posterior region silk glands of 3rd-and 5th-instar D. saccharalis by studying the variation in the critical electrolyte concentration (CEC). Observations of 3rd-instar larvae indicated that malathion, cipermetrina, and neem oil induced increased chromatin condensation that may consequently disable genes. Tests with fipronil showed no alteration in chromatin condensation. With the use of nicosulfuron, there was chromatin and probable gene decompaction. In the 5th-instar larvae, the larval CEC values indicated that malathion and neem oil induced increased chromatin condensation. The CEC values for 5th-instar larvae using cipermetrina, fipronil, and nicosulfuron Agrochemical-induced CEC in sugarcane borer indicated chromatin unpacking. These observations led us to conclude that the quantity of the pesticide does not affect the mortality of these pests, can change the conformation of complexes of DNA, RNA, and protein from the posterior region of silk gland cells of D. saccharalis, activating or repressing the expression of genes related to the defense mechanism of the insect and contributing to the selection and survival of resistant individuals.

“…Fungicide and herbicide application can have direct and/or indirect impacts on soil fauna, fungicides eliminate fungi that serve as food for many orders of soil fauna and result in the death of many individuals [25]. Herbicides kill weeds, decreasing plant material supply and even the soil rhizosphere, reducing the amount of available niches and food for wildlife, thus resulting in the decrease of many microarthropod populations [26,27]. Insecticides directly affect arthropods that live in the soil [28] and negative effects can be detected both in the field and in laboratory tests [29].…”

Abstract:The soil mesofauna plays a role in organic matter comminution and decomposition, and can be used as bioindicators, since they are sensitive to soil management, vegetation and climate changes. Hence, this study aimed to evaluate mesofauna density and diversity in different land use systems to identify faunal relationships with soil properties, management and seasonality. The study area included five land use systems in Ponta Grossa municipality, Paraná State: integrated crop-livestock (ICL), integrated crop-livestock-forestry (ICLF), grazed native pasture (NP), Eucalyptus dunnii plantation (EU) and no-tillage (NT) cropping systems. In each system, eight soil samples for mesofauna were collected with Berlese funnels of 8 cm diameter along a transect in three replicate plots of 50 m × 100 m. For physical and chemical analysis, soil was sampled at five points per plot in two seasons: winter 2012 and autumn 2013. Data were statistically analyzed using ANOVA and Duncan's test (P < 0.05), nonparametric statistics (when necessary) and redundancy analysis (RDA). Diversity was calculated based on the group richness and Simpson index. The main mesofauna groups found were: Acarina, Collembola and Hymenoptera. Diplopoda, Enchytraeidae, Isopoda, Collembola, Hemiptera, Hymenoptera and Coleoptera larvae were more abundant in autumn than winter. Soil moisture was the main factor responsible for higher mesofauna abundance in autumn. Integrated production systems, especially ICLF had similar invertebrate community abundance and composition with EU, while NT favored Oribatid mites, although the use of insecticides, herbicides and fungicides reduced total mesofauna density. Most correlations between mesofauna and physical-chemical attributes in the winter were not observed in the autumn and vice versa, revealing that there are more factors involved in regulating soil mesofauna distribution.

RESUMONo presente estudo avaliou-se o efeito de diferentes doses e modos de aplicação de calcário em plantio direto em campo nativo sobre a fauna edáfica, após cinco anos da aplicação. Organismos da fauna epiedáfica foram coletados com armadilhas tipo Provid e macrorganismos euedáficos utilizando monolitos de solos em duas épocas de amostragem: inverno e verão. Os organismos foram identificados ao nível de classe e ordem. Foram identificados 17 grupos taxonômicos, com ocorrência de cinco classes: Arachnida, Diplopoda, Crustacea, Oligochaeta e Insecta. A abundância de organismos apresentou maior variação em função das diferentes épocas de coleta e não sofreu influência das diferentes doses e modos de aplicação de calcário avaliados. Termos para indexação:Fauna edáfica, manejo do solo, calagem. ABSTRACTIn the present study one evaluated the effect of different methods and levels of lime application on soil under no-tillage system on edaphic fauna, after five years of the application. Organisms of epiedaphic fauna were sampled with "Provid" traps and euedaphics macrorganisms using soil monoliths in two sampling time: winter and summer. The organisms under study were identified in laboratory at class and order levels. One identified 17 taxonomics groups, with five classes: Arachnida, Diplopoda, Crustacea, Oligochaeta and Insecta. The abundance of organisms showed higher variation in function of different sampling time than the levels and methods of lime application.
