Acanthoscelides obtectus 2.jpg. Acanthoscelides Schilsky is a large genus of neotropical bruchid beetles, in which most species show host plant specialization. Antimicrobial activity of the essential oil of rosemary against an array of bacterial and fungal species including Listeria monocytogenes and Aspergillus niger have been reported by Faliero et al. VIDEO LINK: https://youtu.be/wJqy7qymLb8 = Lecture. We examined the phylogeographic structure of A. obtectus by (a) . Low temperatures soon after the cowpeas were stored in the autumn apparently delayed the development of the C. maculatus breeding inside the bags of cowpeas, and the insect population density remained low for 18 weeks. For all other bruchid species evaluated ( Callosobruchus analis , C. chinensis , C. maculatus , and Zabrotes subfasciatus ), the most effective predator density and addition time (five predator pairs at 0 h) resulted in an ∼50% reduction of emerging F . Much of the current research involves testing isolates of different fungi for efficacy. Acanthoscelides obtectus Say, after a synthetic rewiew of the potential chemical methods which may be used in the chemical control of the insectes harmful to the stored bean seeds. Acanthoscelides obtectus Say and Zabrotes subfasciatus Boheman (Coleoptera: Chrysomelidae) are major pests of stored dried beans Phaseoulus vulgaris L. (Fabales: Fabaceae). Stored-product insects varied in their susceptibility to plant compounds (Table 2-supplementary data). Significant insecticidal activity was exhibited only by the 100% 43:2091-2093. The species was described in 1831 by Thomas Say. Early harvest and keeping the soil wet so that the moth larvae cannot reach the potatoes is effective for P. operculella.

The anti-repellent property of rosemary oil to tobacco leaf aphids, Myzus persiacea, is attributed to 13 compounds; the important being linalool, d-1-camphor and α-terpineol (Hori, 1998).

Preharvest application of residual insecticides to kill postharvest insect pests also has been considered a means of reducing field infestations of C. maculatus and Callosobruchus chinensis on mungbeans in Thailand, Sitotroga cerealella and Sitophilus oryzae on maize in India, and Sitophilus zeamais and Rhyzopertha dominica on sorghum in the Philippines (see Chapter 8).

With an increase in the population of less developed countries, in addition to a reduction in agricultural land availability for food production, there is a tendency to replace animal protein with plant proteins in the human diet.

The bean weevil Acanthoscelides obtectus Say (Coleoptera: Chrysomelidae: Bruchinae) can cause significant losses in production of its primary host common bean Phaseolus vulgaris L.

Despite several attempts made to search for and characterize these substances in many leguminous plants, no secondary metabolite has yet been found to be effective against the bruchids Callosobruchus maculatus, which exclusively attacks cowpea, and Zabrotes subfasciatus, which attacks common bean and cowpea (Marsaro and Vilarinho, 2011; Mazzonetto and Vendramim, 2002; Sales et al., 2000). These mechanisms include specific responses that activate different metabolic pathways, which alter their chemical and physical characteristics.

Fumigated dry common beans ( Phaseolus vulgaris L.) that were artificially infested with Acanthoscelides obtectus Say, and others that were not artificially infested, were stored in hermetic triple-layer PICS (Lela Agro, Kano, Nigeria) or woven polypropylene (PP) bags for 6 mo at ambient laboratory temperature conditions of 22.6 ± 1.9°C and 60.1 ± 4.3% relative humidity. excellent control of Acanthoscelides obtectus in both seasons.

Delayed planting of maize reduced field infestation by Sitotroga cerealella in Kentucky, but this technique was not practical.
