“…Lastly, the obtained results matched those reported by Dutta et al (2016) on their field study to evaluate four insecticides against mustard aphid and their toxicity to coccinellid beetles. They found that among the treatments, azadirachtin 1EC appeared to be safest to coccinellid beetles, while indoxacarb 145 SC was found to be toxic.…”

Background For the sake of environmental safety, many new insecticide generations developed. Sulphur formulations and other botanicals or formulated synthetic insecticides were recommended in many integrated pest management programs to protect, particularly, edible vegetables and fruit trees from insect and mite pests as well as plant pathogenic diseases. Such formulations, at the recommended application rates, proved to be safer for mammals. Regarding their safety to beneficial arthropods, diversified results were reported. This study was designed to investigate and evaluate the impact of indoxacarb and sulphur formulation against some natural enemies naturally prevailing in some vegetable crops. Results Application of indoxacarb and sulphur formulation in Okra fields to control aphid was carried out. The adverse effects of these applications against some important predators were investigated. The obtained results revealed that indoxacarb was more effective than sulphur application in all treatments. At the end of the experiment, the percentages of population reductions of Coccinella indoxacarb treatment reached ≈ 92 and 76% for larvae and adults, respectively. The corresponding figures for Chrysoperla were ≈ 79 and 82% for larvae and adults, respectively. Indoxacarb-induced reduction in the Paederus population reached about 80%, while sulphur formulation had negative effects. Both indoxacarb and sulphur formulations were harmful to the aphid, inducing about 97 and 26% reduction, respectively, for the mean number of aphid populations. Conclusion It could be concluded that indoxacarb is more hazardous towards different natural enemies prevailing naturally in open fields at anywhere season round the year, and care must be in consideration when we choose and select some insecticides to kill or to eradicate pests and simultaneously conserve the natural enemies.

“…The pooled data on the incidence reveal that dimethoate 30%EC is significantly more effective against L. erysimi (93.09 and 92.94% reduction after three days in first and second treatment, respectively) followed by pyriproxyfen 10%EC and buprofezin 25%SC. Gaikwad et al (2014), Choudhary and Singh (2015), Dutta et al (2016) and Sharma et al (2017) also observed that dimethoate 30%EC is more effective. With pyriproxyfen 10%EC, buprofezin 25%SC, emamectin benzoate 5%SG and pymetrozine 50%WG reduction in incidence ranged from 90.70-79.10% with first, and 90.37-78.51% with second spray, respectively, after three days of spray.…”

A field experiment on the efficacy of biopesticides and newer insecticides against mustard aphid, Lipaphis erysimi (Kalt.) was conducted during 2016-17 and 2017-18. The treatment dimethoate 30%EC was found to be the most effective followed by pyriproxyfen 10%EC and buprofezin 25%SC. The maximum seed yield was obtained with dimethoate 30%EC (13.31 q ha-1) followed by pyriproxyfen 10%EC (13.07 q ha-1), buprofezin 25%SC (12.83 q ha-1) and pymetrozine 50%WG (11.79 q ha-1). The maximum net return was obtained with dimethoate 30%EC (`21,231.00 ha-1) followed by buprofezin 25%SC (`18,661.00 ha-1) and pyriproxyfen 10%EC (`17,756.00 ha-1), of which dimethoate 30%EC adversely affected the predator Coccinella septempunctata L.

“…The findings of this study revealed that, imidacloprid, botanical mix, and neem seed extract were proved relatively safer to the lady bird beetles. Similarly, Dutta et al (2016) reported that azadiractin 1% EC was less toxic product to coccinellid beetles and foraging honey bees. On the contrary, Ali and Zedan (2015) studied the nontarget effect of five insecticides (viz.…”

Cabbage aphid, Brevicoryne brassicae (L.) is one of the major insect pests of brassica crops worldwide. Mainly insecticides are being used for its management which poses hazardous effects on the environment and the applicator. Low efficacy and non-target effect of the available insecticide are the main challenge in the management of the pest in Ethiopia. The use of bio-rational and neonicotinoid pesticides is a promising alternative as they are less vulnerable to resistance development and relatively safe to the environment and the applicator. This study was carried out in 2018/19 cropping season to evaluate the efficacy of plant derived and synthetic insecticides for the management of cabbage aphid and their effect on coccinellid predators on Ethiopian kale. Ten treatments including six synthetic and two botanical insecticides were tested in comparison with the standard check dimethoate 40% EC and the untreated control in Randomized Complete Block Design with three replications. Significant (P<0.05) differences were observed among the treatments in terms of cabbage aphid population reduction and their effect on coccinellid beetles. The botanical mix (Garlic+onion+pepper) and imidacloprid were at par with each other and found to be the best treatment with 93.79% and 91.04% efficacy, respectively. The maximum leaf yield was obtained from imidacloprid (14.18 t/ha) followed by botanical mix (13.45 t/ha) and lufenuron (12.42 t/ha). The highest yield increment over control was obtained from imidacloprid (3.1 t/ha), followed by botanical mix (2.37 t/ha). The botanical mix, imidacloprid and neem seed extract were highly effective in aphid control as well as less hazardous to ladybird beetle (Coccinella septempunctata L.). The highest cost benefit ratio was recorded with profenofos (1:1.14) followed by lufenuron (1:0.2), spinosad and nimbecidine (1:0.18). Results of the current study demonstrated that imidacloprid and plant-based insecticides can reduce aphid populations equally to conventional insecticides and could be used as an alternative component for the integrated pest management (IPM) of cabbage aphid, Brevicoryne brassicae (L.) on kale crop under field condition of smallholder farming system.
