Effectiveness of indigenous plant powders as grain protectant against Callosobruchus chinensis (L.) in stored chickpea (Cicer arietinum)

Abstract

The effectiveness of 17 indigenous plant powders as grain protectant were assessed against Callosobruchus chinensis (L.). The results indicated that among all the tested plant materials, tobacco leaf powder (TLP) had promising effects on inhibiting oviposition and reducing adult emergence, seed infestation, and weight loss by C. chinensis. Tobacco leaf powder offered complete protection of chickpea seeds applied at 20.0 g/kg seeds. Its lower doses exhibited efficacy in dose dependant manner. The lowest number of eggs (24.60), egg bearing seeds (23.40), adult emergence (23.20), seed infestation (8.28%), and weight loss (0.50%) were obtained from the TLP treated at 10.0 g/kg seeds, while the highest of these parameters were in untreated control. In the ovicidal test, TLP showed 100% inhibition at 20.0 g/kg seeds over control. The lowest number of adults (37.20) were emerged when larvae bearing seeds were treated with TLP at 20.0 g/kg seeds along with 59.39% retardation over the control and had no adverse effect on seed germination up to 3 months.

Efficacy of Different Grain Protectants on the Effect of Fecundity, Adult Emergence and Weight Loss of Cigarette Beetle (Lasioderma serricorne Fabricius) Infestation in Cured Turmeric Rhizomes (Curcuma longa Linnaeus)

“…Among the botanicals, neem seed kernel powder and vitex leaf powder applied @ 5 and 10 g kg -1 to cured turmeric rhizomes were most effective in reducing the fecundity of the insect and the two treatments were significantly different from each other. Similar results were obtained by Hossain et al, (2014) who reported that neem seed kernel powder was effective in reducing the fecundity and giving complete protection from C. chinensis while, Khalequzzaman and Osman (2009) revealed that seed kernel powder of Azadirachta indica, leaves of Vitex negundo and Annona squamosa were effective against the control of Callosobruchus maculatus and C. chinensis adults in increasing the mortality and reducing the oviposition. The results were in agreement with the findings of Senguttuvan et al, (1995) and Singh et al, (1996) who reported that the neem seed kernel powder was superior and adjudged as the best treatment for the control of most of the stored product pests in different commodities.…”

“…Khalequzzaman and Osman (2009) reported that among the plant materials tested in cowpea seeds against Callosobruchus maculatus and C. chinensis for weight loss, neem seed kernel powder recorded lowest percentage of weight loss than vitex leaf powder. Hossain et al, (2014) reported that seed kernel powder of Azadirachta indica as grain protectant against Callosobruchus chinensis resulted in reducing mortality, adult emergence and weight loss of seed than the untreated control. Similar findings also reported by Chebet et al, (2013) against larger grain borer, Prostephanus truncates.…”

Eco-friendly Techniques Against Pulse Beetle in Seeds Under Storage: An Insight

“…After the use of neem oil as a grain protectant, the parental mortality was found to be 91.70% (Meghwal et al, 2007). Hossain et al (2014) observed that the seed oils of sesame, castor, neem, and karanj (4 to 8 ml/kg) showed a substantial reduction in weight loss of chickpea seeds and seed infestation. The use of edible oils against pulse beetles is safe and effective without any harmful effect to the human beings (Nair et al, 2020).…”

Biology of pulse beetle, Callosobruchus maculatus (Fab.) infesting cowpea

“…Moreover, Pulses are rich in energy, proteins, vitamins, minerals and essential amino acids. Grain legumes are popularly known as pulses (Bharati et al, 2017) [1] which contain 30-40 percent protein that is almost twice than cereals and hence, known as 'poor man's meat' (Hossain et al, 2014) [2] . Annual weight loss in storage losses of pulses in India reported to be 55-60 percent and 45.5 to 66.3 percent loss in protein content of seed (Hosamani et al, 2018) [3] .…”
