“…The negative influence of HF+ on the earthworm population in relation to HF− on faba bean fields was apparent in the decrease in individual density and their biomass. Many authors reported a reduction in growth, biomass loss, decreased cocoon production or higher mortality after pesticide application [75][76][77][78][79]. Biomass reduction may be an effect of reduced food intake as a strategy to avoid contamination.…”

Earthworm species composition, the density of individuals, and their biomass were investigated in spring barley and faba bean fields in a long-term (52-year) experiment conducted at the Production and Experimental Station in Bałcyny, in north-eastern Poland (53°40′ N; 19°50′ E). Additionally, post-harvest residues biomass, soil organic matter (SOM), and soil pH were recorded. The above traits were investigated using two experimental factors: I. cropping system—continuous cropping (CC) vs. crop rotation (CR) and II. pesticide plant protection: herbicide + fungicide (HF+) vs. no plant protection (HF−). A total of three species of Lumbricidae were found: Aporrectodea caliginosa (Sav.) in both crops, Aporrectodea rosea (Sav.) in spring barley, and Lumbricus terrestris (L.) in faba bean. The density and biomass of earthworms were unaffected by experimental treatments in spring barley fields, whereas in faba bean CC increased and HF+ decreased earthworm density and biomass in comparison with CR and HF− respectively. Total post-harvest residues in faba bean fields were higher under CC in relation to CR and under HF+ compared with HF− treatment in both crops. Compared to CR, CC increased soil pH in spring barley fields and decreased in faba bean fields. Experimental factors did not affect SOM. Earthworm density and biomass were positively correlated with SOM content.

“…Similar findings were also reported by Izawa et al (1985) who found that the death of Nilaparvata lugens nymphs α treated with buprofezin was attributed to the chitin synthesis inhibitors act during metamorphosis which causes abortive molting. Badawy et al (2013) noted that a significant growth inhibition on the earthworm, Aporrectodea caliginosa, was also seen when exposed to buprofezin and triflumuron. Buprofezin and triflumuron are chitin synthesis inhibitors, act by interfering with chitin synthesis.…”

“…IGRs differ widely from the commonly used insecticides, as they exert their insecticidal effects through their influence on development, metamorphosis and reproduction of the target insects by disrupting the normal activity of the endocrine system (Khan, 2016;Dhadialla et al, 1998;Retnakaran et al, 1985;Khatun et al, 2017;Khatter, 2015). These compounds have been tested successfully against several insect species namely, the papaya mealybug Paracoccus marginatus (Khan, 2016); the cotton leaf worm Spodoptera littoralis (Khatter, 2015;Nasr et al, 2010); the brown planthopper Nilaparvata lugens (Kanaoka et al, 1996;Uchida et al, 1985;Izawa et al, 1985); the rice weevil Sitophilus oryzae (Das, 2013;Merzendorfer & Zimoch, 2003); the earthworm Aporrectodea caliginosa (Badawy et al, 2013); brinjal shoot and fruit borer Leucinodes orbonalis (Das & Islam, 2014); the sweet potato whitefly Bemisia tabaci (Ishaaya et al, 1998); and the Colorado potato beetle Leptinotarsa decemlineata (Karimzadeh et al, 2007).…”

Laboratory bioassays were conducted to compare the effects of the leaf extract of Acalypha indica L. (Euphorbiaceae) with synthetic insect growth regulators (IGRs) triflumuron and buprofezin against Spodoptera litura (F.). The experiment was set up as a randomized complete block design (RCBD). The treatments were two concentrations of A. indica extracts 1000 and 2000 ppm, two concentrations of buprofezin 100 and 200 ppm, two concentrations of triflumuron 120 and 240 ppm and control. Each treatment was replicated three times. Second instar larva of S. litura were used for the bioassays. Mortality and biological variables of treated and control larvae were recorded daily. The results indicated that the application of A. indica extracts and synthetic IGRs (buprofezin & triflumuron) significantly caused the S. litura mortality throughout the experimental period. At first, the toxicity of triflumuron on larval S. litura was significantly higher compared to those of buprofezin and Acalypha indica leaf extract. However, at the end of experimental period all treatments caused high mortality on S. litura, and those all were significantly different from control. The treatments also caused abnorrmal growth in larval, pupal, and adult stages. While in the control, larvae molted into normal adults. The results indicated that the use of biorational control agents such as synthetic insect growth regulators (IGRs) and those based on naturally derived products such as botanical insecticides show promise as a potential tool in S. litura management programs.

“…In the fauna of soil-dwelling invertebrates, earthworms are more significant organisms (Fouad et al 2023). Several studies from a long time ago have reported on their favourable effects in the agricultural soils (Badawy et al 2013;Fouad 2021Fouad , et al 2023.…”

Abstract. El-Aswad AF, Fouad MR, Aly MI. 2023. Assessment of the acute toxicity of agrochemicals on earthworm (Aporrectodea caliginosa) using filter paper contact and soil mixing tests. Asian J Agric 7: 14-19. Earthworms are suitable bioindicators of chemical contamination in terrestrial ecosystems. Therefore, adult earthworms (Aporrectodea caliginosa Savigny, 1826), which are common in Egyptian rice fields were used to study the side effects of fenitrothion and thiobencarb. Also, it was used two common Egyptian soil types; alluvial soil (clay soil) and the calcareous soil (sandy clay loam soil). Two tests were used; filter paper contact test at 24, 48 and 72 h, and the soil mixing test at 5 and 10 days. The effect of both pesticides on mortality of earthworm was insignificant at 24 h with a low mortality percentage. LC50 value of fenitrothion and thiobencarb were 83.16, 288.26, 24.67, and 39.98 µg a.i mL-1 at 48 and 72 h, respectively. Based on the LC50 values, fenitrothion was 3.5 and 1.6 times more toxic than thiobencarb at 48 and 72 h, respectively. At 5 and 10 days after treatment, respectively, the LC50 for fenitrothion in the soil mixing test decreased from 334.27 to 55.45 in clay soil and from (415.90) to (25.00) in sandy soil. Regarding to fenitrothion in soil mixing test, the LC50 was reduced from 334.27 to 55.45 in clay soil and from 415.90 to 25.00 in sandy soil at 5 and 10 days after treatment, respectively. Also, the LC50 of thiobencarb in clay soil was decreased from 0.93 to 0.41 and from 55.28 to 10.65 at 5 and 10 days, respectively. In general, a positive relation was recorded between the tested pesticide toxicity on earthworm and concentrations, and also exposure time. Fenitrothion was more toxic on earthworm in contact filter paper test than thiobencarb. While, in clay soil, fenitrothion was least toxic to the earthworm in soil mixing test, this could be attributed to the slow degradation in the worms and subsequently less elimination of the metabolites as well as attributed to its higher adsorption and lower desorption in soil.
