“…Jiequn et al (2019) reported that Chlorfenapyr (8% ME) treated mulberry leaves fed to silkworms 15 and 30 days after spray exhibited a cocoon shell ratio of 19.06 and 18.09 per cent, respectively. Bhagyalakshmi et al (1995) studied the effect of Hexachlorocyclohexane (HCH) on silkworms and reported a considerable reduction in cocoon weight and cocoon shell ratio due to HCH treatment.…”

A bioassay study was conducted to test the effect of feeding pesticides sprayed mulberry leaves on silkworms. The pesticides that are used to control mulberry pests were selected with the recommended dose as per the label claim and were sprayed on mulberry plants and fed to silkworms (FC1) at 5, 10, 15 and 20 days after spraying (DAS) to know their impact on the growth of silkworms. The results revealed that among the five pesticides tested, Azadirachtin 1 per cent (2 mL/L) and Chlorfenapyr 10 SC (1.5 mL/L) were highly toxic to silkworms with maximum larval mortality of 100 and 23.5 per cent even at 10 days after spray, but less toxic at 15 days after spray, respectively. However, the pesticide Orgomite (2.5 mL/L) a botanical formulation recorded the least mortality of silkworm (7.83%) at 10 days after spray. Whereas, the pesticides Wettable Sulphur 80 WP (2 g/l) and Era Safeguard (2.5 mL/L) at 10 DAS recorded less mortality of 8.30 and 17.25 per cent, respectively. Similar trends were recorded with regard to the rearing parameters of silkworms. The findings of the current study have clearly shown that the Orgomite which is a botanical formulation was proved to be the least toxic to silkworms even at 10 DAS followed by Wettable Sulphur 80 WP, Era Safeguard, Chlorfenapyr 10 SC and Azadirachtin 1 per cent at 15 DAS. Thus, Orgomite and Chlorfenapyr 10 SC were found best for the management of both mites and leaf roller with a safety period of 10 and 15 days after pesticide spray, respectively.

“…Organochloride insecticides, like Hexachlorocyclohexane, were reported to cause a decrease in fibroin content, pupal weight and fecundity as well as deterioration in quality and quantity of silk thread in B. mori (for detail see Bhagyalakshmi et al, 1995;Li et al, 2010).…”

“…However, the survival of silkworm has been significantly affected by organophosphorus (OP) insecticides such as phoxim [O,O‐diethylO‐(alpha‐cyanobenzylideneamino)phosphorothioate], which can enter mulberry plantations by aerial application and water currents (Nath, ; Li et al, ), resulting in a threat to sericulture, a more than 30% reduction in raw silk, decreased acetylcholinesterase gene expression, and oxidative stress in B. mori (Li et al, ; Peng et al, ; Yu et al, ). In addition, toxicity of the organochloride insecticide, hexachlorocyclohexane (HCH), on damage to the growth of silkworms and silk quality has also been investigated (Bhagyalakshmia et al ). However, the mechanisms involved in the reduction of raw silk caused by OP insecticide exposure are still unknown.…”

It is known that exposure to organophosphorus pesticides (OP) including phoxim can produce oxidative stress, neurotoxicity, and greatly attenuate cocooning rate in the silkworm, Bombyx mori. Cerium treatment has been demonstrated to relieve phoxim-induced toxicity in B. mori; however, very little is known about the molecular mechanisms of silk gland injury due to OP exposure and protection of gland damage due to cerium pretreatment. The aim of this study was to evaluate silk gland damage and its molecular mechanisms in phoxim-induced silkworm toxicity and the protective mechanisms of cerium following exposure to phoxim. The results showed that phoxim exposure resulted in severe gland damage, reductions in protein synthesis and the cocooning rate of silkworms. Cerium (Ce) attenuated gland damage caused by phoxim, promoted protein synthesis, increased the antioxidant capacity of the gland and increased the cocooning rate of B. mori. Furthermore, digital gene expression data suggested that phoxim exposure led to significant up-regulation of 714 genes and down-regulation of 120 genes. Of these genes, 122 were related to protein metabolism, specifically, the down-regulated Ser2, Ser3, Fib-L, P25, and CYP450. Ce pretreatment resulted in up-regulation of 162 genes, and down-regulation of 141 genes, importantly, Ser2, Ser3, Fib-L, P25, and CYP333B8 were up-regulated. Treatment with CeCl3 + phoxim resulted in higher levels of Fib-L, P25, Ser2, Ser3, CAT, TPx, and CYP333B8 expression in the silk gland of silkworms. These findings indicated that Ce increased cocooning rate via the promotion of silk protein synthesis-related gene expression in the gland under phoxim-induced toxicity. These findings may expand the application of rare earths in sericulture.
