“…Some species have been reported as widely introduced around the world by human activities, such as gardening, cultivation of plants, and soil transport (Iniesta et al, 2021). Additionally, species have been regarded as agricultural pests in some poly-or monocultures, feeding on seedlings of fern, soybean, coffee, lettuce, tuber, and ornamental plants (Schubart, 1942;1945;Lordello, 1954;Domiciano & Fontes, 2001;Link & Link, 2001;Ebregt et al, 2005;Salvadori et al, 2007;David, 2015).…”

Millipedes are known by their importance in ecological systems, although some species are regarded as agricultural pests in some poly- or monocultures. Canola (Brassicaceae: Brassica spp.) is an important feedstock for biodiesel production and a potential ingredient in the food industry, but with several arthropod pests causing damage to its cultivation. In this perspective, this study reports the still unknown relation of millipedes with cultivation of canola. Pitfall traps were plotted in cultivation of Brassica napus L. var. oleifera in Passo Fundo, Rio Grande do Sul state, Brazil, and checked weekly during the years of 2015 and 2016. A total of 66 individuals were captured in 2015 and 41 individuals in 2016, all belonging to the families Chelodesmidae and Paradoxosomatidae (Polydesmida). The most abundant species sampled in both years was Brasilodesmus austrocrucis Hoffman, 1981, with 100 specimens in total. Catharosomatini sp. was recorded with 4 specimens, Brasilodesmus triseriatus (Attems, 1931) with 2 specimens, and Oncoleptodesmus uniconus (Attems, 1931) with only one specimen. In the present study, the sampled species were not reported causing any damage to crops, suggesting that millipedes may not be considered pests in canola.

“…Populations of O. gracilis are mostly found in greenhouses worldwide and are widely registered for United States, Europe, Australia, and Central America (Hoffman, 1999;Suriel, 2012;Nguyen & Sierwald, 2013;Jovanovi et al, 2016). In South America it has been cited for Peru (Kraus, 1955), Chile (Chamberlin, 1957), Brazil (Schubart, 1942(Schubart, , 1947Boock & Lordello, 1952;Lordello, 1954;Santos da Silva et al, 2001;Iniesta et al, 2020) and Argentina (Mauriés, 1998;Agnolin et al, 2019). O. gracilis differs from other Paradoxosomatidae species also widely distributed by trade, and from its congeners by morphological differences of the male modified walking legs used for sperm transfer, the gonopods (Suriel, 2012;Nguyen et al, 2017).…”

“…Despite providing benefits for soil fertility, millipedes can become agricultural and urban pests when environmental imbalances and climate changes trigger population outbreaks. Millipedes species are known to damage newly germinated seedlings, roots, and fruits in crops, leading to economic loss in rural areas worldwide (Lordello, 1954; Winder et al, 1993; Wightman & Wightman, 1994; Ebregt et al, 2004 a , 2004 b ). In urban environments, migration and demographic explosions of millipedes are also reported (Cloudsley-Thompson, 1949; Niijima & Shinohara, 1988; Boccardo et al, 2002; Fontanetti et al, 2010).…”

“…The species Gymnostreptus olivaceus (Spirostreptidae) was chosen for the tests since it can be found both in forests and cultivated areas. These millipedes were responsible for total loss of melon and beetroot crops in Piracicaba, São Paulo, Brazil, in 1952 (Lordello, 1954). Currently, millipedes of the species G. olivaceus are abundant in the region of study and may invade urban areas and damage home gardens.…”

Changes in Synapsin Levels in the Millipede Gymnostreptus olivaceus Schubart, 1944 Exposed to Different Concentrations of Deltamethrin

et al. 2016

Millipedes are ecologically important soil organisms and may also be an economically threatening species in rural and urban areas when population outbreaks occur. In order to control infestations commercial formulations of deltamethrin have been commonly applied, even though there are few studies about the effects of such insecticide on millipedes. This paper describes the effects of this insecticide on millipedes showing neurotoxic effects assessed by synapsin labeling and confocal microscopy. Deltamethrin concentrations related to the DL50 of the active ingredient and a field concentration were applied topically in the diplopod Gymnostreptus olivaceus to evaluate the behavior, mortality rate, and synapsin levels in the brain 12, 24, and 48h after contact with deltamethin. The insecticide caused mortality at the higher concentrations employed, in which no change was observed in neurotransmission in the survivors. In contrast, at field concentrations, deltamethrin did not cause any deaths, but triggered significant changes in synapsin levels. The results obtained form the synapsin labeling provide several interpretations suggesting that the isolated application of this tool must be associated with additional tools in order to evaluate biologically induced effects of deltamethrin in an accurate way. In addition, the feasibility of chemical control of millipedes with deltamethrin is questioned.
