“…Of all orders identified, Isopoda and Isoptera stand out. Isopoda was an indicator of OC, being associated with high TOC values, while Isoptera was an indicator of IA, being associated with high MBC values (Jouquet et al, 2005;Karanja et al, 2009;Paoletti, 1999). For the enzymes, it was possible to visualize a higher activity in the OC, and again the relationship between Isopoda and OC was detected (Figure 2).…”

“…By analyzing the faunal structures with the trap method, the high density of Isopoda in the OC was the most evident aspect of the soil fauna evaluation, indicating areas with low pesticide use and with high organic matter content (Karanja et al, 2009;Paoletti, 1999). In the IA area a greater occurrence of Isoptera was correlated with a higher MBC, which may be related to higher presence of fungus in these areas (Jouquet et al, 2005;Riggins et al, 2014).…”

Brazil is the biggest coffee producer in the world and different plantation management systems have been applied to improve sustainability and soil quality. Little is known about the environmental effects of these different management systems, therefore, the goal of this study was to use soil biological parameters as indicators of changes. Soils from plantations in Southeastern Brazil with conventional (CC), organic (OC) and integrated management systems containing intercropping of Brachiaria decumbens (IB) or Arachis pintoi (IA) were sampled. Total organic carbon (TOC), microbial biomass carbon (MBC) and nitrogen (MBN), microbial activity (C-CO 2 ), metabolic quotient (qCO 2 ), the enzymes dehydrogenase, urease, acid phosphatase and arylsulphatase, arbuscular mycorrhizal fungi (AMF) colonization and number of spores and soil fauna were evaluated. The greatest difference between the management systems was seen in soil organic matter content. The largest quantity of TOC was found in the OC, and the smallest was found in IA. TOC content influenced soil biological parameters. The use of all combined attributes was necessary to distinguish the four systems. Each management presented distinct faunal structure, and the data obtained with the trap method was more reliable than the TSBF (Tropical Soils) method. A canonic correlation analysis showed that Isopoda was correlated with TOC and the most abundant order with OC. Isoptera was the most abundant faunal order in IA and correlated with MBC. Overall, OC had higher values for most of the biological measurements and higher populations of Oligochaeta and Isopoda, corroborating with the concept that the OC is a more sustainable system.

“…Holland and Luff 2000;Belaoussoff et al 2003;Minarro and Dapena 2003), studies in invertebrate biodiversity, in relation to both landscape variables and farm management, are rare (Weibull et al 2003). Few studies are broad enough to attempt to address the question of the effects of management practices on the surrounding environment (Cairns et al 1993;Paoletti 1999), in the way invertebrates are now used in aquatic biomonitoring.…”

There is increasing interest in developing environmental management systems to ensure that agricultural industries are sustainable; invertebrate indicators provide one potential tool for monitoring sustainable production. As a first step in developing invertebrate indicators for viticulture, we compare the efficiency of 3 common trapping methods in assessing populations of relevant orders of invertebrates. Yellow sticky traps were more effective in trapping Hymenoptera, Thysanoptera, Hemiptera, Diptera, Araneae and Coleoptera; transparent sticky traps were best for Lepidoptera and Neuroptera; and pitfall traps for Collembola and the family Formicidae. Numbers collected differed among months and December was the best month, overall, for trapping. Preliminary guidelines are developed for assessing key orders. While several methods are required for assessing invertebrate biodiversity, most orders can be sampled with a single method, particularly the yellow sticky trap. Our results indicate that changes in numbers of beneficial orders, due to changes in management practices, can be detected. Power analyses suggest a relatively small number of yellow sticky traps would be sufficient to detect changes of around 30%, or greater.

“…In south‐central Ontario, Canada, Boutin, Pamela, and Martin () found that woody hedgerows adjacent to organic and conventional farms presented the greatest abundance of beneficial arthropods, whereas the abundance of phytophagous arthropods was greatest in crop fields. The abundance and species richness of Hymenoptera in an agroecosystem are considered as a biomarker of low disturbance for their role as important beneficial group for pollination, predation, and parasitism (Kevan, ; La Salle & Gauld, ; Paoletti, ). Similar results were found by Mujica () on foliage‐inhabiting arthropod guilds in potato without application of insecticides, where species richness and abundance of entomophagous (44%, 49 spp.)…”

Integrated pest management (IPM) versus farmers’ pest management practices were evaluated in potato (Solanum tuberosum L.) in the central coast of Peru. IPM technologies consisted of seed treatment, insect pest, and disease scouting using action thresholds for decision making to apply pesticides, and the use of trapping devices and selective insecticides versus chemical control by potato farmers. An ecological, environmental, and economic analysis of both approaches was carried out by using biodiversity indices, environmental impact indicators, and partial budget analysis. The leafminer fly Liriomyza huidobrensis (Blanchard) and the bud midge Prodiplosis longifila (Gagne) were the most important pests during the cropping season. Larval infestation of both pests and leafminer foliar damage were less in IPM plots. Almost twice as many pesticide (insecticide and fungicide) applications per season were carried out on farmers’ practices plots with 16.7 sprayings compared to 9.7 sprayings in IPM plots. The total quantity of pesticides used per season was higher under farmers’ practices (4,614.3 g a.i./ha) than in IPM (2,042.6 g a.i./ha) plots. Likewise, farmers applied five times more insecticides (3,620.3 g a.i./ha) than IPM (722.55 g a.i./ha). Methamidophos and chlorpyrifos accounted for 65% of the environmental impact (EI) value of 137/ha in farmers’ fields. IPM strategies reduced the EI to 42.4/ha, which represents a reduction of 69.2%. Further, IPM achieved 35% higher marketable potato yield than farmers’ practices. Partial budget analysis showed a higher net profit in all IPM plots, with an average increase of US$1,410/ha. The field trials demonstrated the environmental and economic viability of IPM for potato in the central coast of Peru. However, while there are effective integrated components for leafminer fly management, there is a clear need to develop and integrate more sustainable and ecological pest management strategies for other economically important pests such as the bud midge.
