“…Julidae play an important role (Gere, 1956;Brygadyrenko, 2015Brygadyrenko, , 2016 in functioning of both agrocenoses and adjacent natural ecosystems (forests, steppes, meadow areas). The effect of chemical pollutants on the organisms of Julidae is not studied sufficiently (Brygadyrenko & Ivanyshyn, 2015;Douglas et al, 2017Douglas et al, , 2019Kozak & Brygadyrenko, 2018;De Souza et al, 2019;Tóth & Hornung, 2019), while the effect of agrochemicals is practically unstudied. The most abundant diplopod in Central and Southern Ukraine is Rossiulus kessleri (Lochmander, 1927).…”

Influence of herbicides, insecticides and fungicides on food consumption and body weight of Rossiulus kessleri (Diplopoda, Julidae)

Pesticides kill organisms harmful for the human organism, sometimes also harming beneficial ones. After treatment, pesticides remain on the soil surface in agrocenoses and adjacent plots for decades. For the laboratory experiment, we selected Rossiulus kessleri (Lochmander, 1927) – a species which lives 5–6 years on the soil surface and can dig in to soil to a depth of 30–40 cm. During a 20-day experiment we used herbicides (Roundup, Urahan Forte), insecticides (Omite, BI 58, Biotlin, Actellic, Nurelle D) and fungicides (Ridomil Gold, Thiovit Jet, Penncozeb 80 WP, Falcon, Tilt, Horus) which are often used in agrocenosises of Ukraine. Under the impact of Roundup and Urahan, body weight of R. kessleri reliably did not change, but food consumption and production of excrement increased. Pesticide-treated litter did not digest in the intestine of millipedes, but they survived to the end of the experiment (20 days). In the conditions of treating litter with insecticides Omite, BI 58, Biotlin, Actellic and Nurelle D, the amount of consumed food and body weight reliably did not change; most of these insecticides slowed the formation of feces in the millipedes. The highest studied concentrations of Actellic and Nurelle D preparations caused death to R. kessleri. Depending on the concentration in the litter, the studied fungicides Ridomil Gold, Thiovit Jet, Penncozeb, Falcon, Tilt, Horus had a varying effect on food consumption, body weight and the amount of excrement of R. kessleri. Thus, in agrocenoses and forest ecosystems adjacent to them (windbreaks, ravine and flood plain forests), R. kessleri can be significantly affected by the manufacturer-recommended doses of pesticides, as well as more than ten-fold lower doses.

“…14 Although millipedes can be highly destructive agricultural pests, they are still considered keystone species in their ecosystems and are used as indicator species in ecotoxicology studies, 6 evaluating soil contamination and other environmental pollutants. 9,14,36 Millipedes have varied morphologies and sizes, some with vibrant colors, and are generally docile, making them ideal for zoological exhibits and educational encounter programs. They may be housed successfully in mixed species exhibits as they are nonaggressive, and most are herbivorous.…”

Histopathologic data of millipedes are scarce. Little is known about health and disease of these invertebrates despite their exhibition at zoological institutions and use in ecotoxicological studies. In a retrospective study of 69 zoo-housed giant African millipedes ( Archispirostreptus gigas) submitted between 2018 and 2021, most deaths occurred during midwinter and in 2021. The most common lesion was inflammation ( n = 55; 80%). Necrosis was seen concurrently in 31 (45%) millipedes and of these, bacteria (20; 29%) and fungi (7; 10%) were detected in lesions. Inflammation was seen in the head/collum (20; 29%), hemocoel (16; 23%), and appendages (9; 13%), specifically in perivisceral fat body (42; 61%), gut (16; 23%), tracheae (26; 38%), skeletal muscle (24; 35%), and ventral nerve (17; 25%). Inflammatory cell types and patterns included agranular hemocytes (61; 88%), granular hemocytes (39; 57%), and nodulation/encapsulation (47; 68%) often accompanied by melanization. The oral cavity or gut (ingestion), spiracles (inhalation), or cuticular defects were considered plausible routes of bacterial entry. Metazoan parasites (adult nematodes: 2, 3%; trematode ova: 2, 3%; and arthropods: 1, 1%) were associated with gut necrosis and inflammation in 5 millipedes. In addition, adult nematodes were noted in the gut of 4 millipedes without lesions. Neoplasia was not detected in any millipedes. Speculatively, environmental factors may have predisposed to disease, as most deaths occurred during winter months. Disease surveillance of millipedes is critical to optimize husbandry practices in zoo populations and investigate potential impacts of environmental degradation and climate change on wild millipedes.
