“…To decrease insect consumption of host cultivars via antibiosis, plants may use toxic compounds that confer resistance by delaying the development of immature stages of pests (Panda and Khush 1995). Toxic components of plant defense include antibiotics, alkaloids, terpenes, cyanogenic glycosides, and proteins (Minney et al 1990;Gepts 1999;Sakthivelkumar et al 2013). The type of grain proteins that are typically associated with defense mechanisms are lectins, alpha-amylase inhibitors, proteinase inhibitors, inactivating-protein ribosomes, protein reserves (vicilin) of modified proteins, proteins involved in lipid transport, and glucanases (Chrispeels and Raikhel 1991;Kasahara et al 1996;Grossi de Sá and Chrispeels 1997;Franco et al 1999;Carlini and Grossi de Sá 2002).…”

“…Arcelin is found in resistant wild varieties but is absent in many susceptible commercial and wild varieties (Romero Andreas et al 1986;Cardona et al 1990;Blair et al 2010;Zaugg et al 2013). Based on previous studies, arcelin, found in several wild genotypes, is associated with resistance in common beans (Osborn et al 1986(Osborn et al , 1988Romero Andreas et al 1986;Cardona et al 1989Cardona et al , 1990Minney et al 1990;Velten et al 2007), and types 1, 2, and 5 are the most resistant against bruchids (Barbosa et al 1999;Baldin and Lara 2008;Sakthivelkumar et al 2013). Arcelin prolongs immature development of A. obtectus by 15% (Schmale et al 2002) and acts as a growth inhibitor on first instar larvae.…”

The bean weevil Acanthoscelides obtectus (Say, 1831) (Coleoptera: Bruchidae) is one of the most serious pests of stored beans worldwide because of the damage it causes to grains within warehouses. The use of resistant genotypes may offer a control strategy for this pest. In the current study, we screened common bean genotypes of Andean American and Mesoamerican origin in laboratory and greenhouse bioassays to select the most promising beans for resistance to the bean weevil. In the laboratory, we evaluated number of eggs, period of development (eggadult), number of emerged adults, dry weight of adults, and weight of consumed grains. In the greenhouse, number of pods per plant and number of grains per pod were evaluated. We also assessed the percentages of damaged pods per plant and damaged grains per pod. Combining the results obtained in the laboratory and greenhouse assays, the common bean genotypes Arc.1, Arc.2, Arc.1S, Arc.5S, and Arc.3S were identified as resistance expressing antibiosis against A. obtectus. The lowest percentages of damaged pods were found in the Arc.1 and Arc.1S genotypes, and their resistance to damage was apparently morphological (antixenotic) because they possessed structures that prevented contact between larvae and grains. The use of resistant genotypes in combination with other techniques may improve management of the weevil. Additionally, the resistant genotypes identified here can be used in breeding programs to develop common bean lines with resistance to A. obtectus.

“…Hence, with the decrease in the binding energy of the receptorligand complexes, the efficiency of the ligand to the enzyme increases. In this case, salicylic acid has greater affinity to bind in the pocket 63 but less likely to bind in the pocket 62, 61 and 60 [43].…”

Plants defense system protects themselves from pathogens in two ways by preformed mechanisms and through infection-induced responses of the immune system. It is always apparent as a restriction of pathogen growth and spread to a little zone around the infected area. During localized cell death, the visible necrotic lesion evokes up and induces the programmed cell death (apoptosis). Systemic acquired resistance (SAR) will be helpful to the infected plants after a period of 5-7 days. Salicylic acid (SA) is a plant hormone essential for the immunity in plants. SA has been found to involve in the control of microbe/pathogenassociated molecular pattern triggered immunity, effectortriggered immunity and system acquired resistance (SAR). The binding modes and the bonding pattern between salicylic acid and the enzyme catalase is still unknown. In our study, the different binding modes of salicylic acid in different pockets were analyzed. Among the chosen pockets, the best probable binding pocket was identified computationally based on the binding energy, intra-molecular energy, internal energy and inhibition constant between two molecules.

“…However, the smaller number of emerged adults, the decrease of larval viability, and the delayed egg-to-adult developmental time of the genotypes tested may be an indicative of antibiosis resistance (Baldin et al 2019). These results are possibly related to toxic compounds that delay the development of immature stages of insect pests, such as antibiotics, alkaloids, terpenes, cyanogenic glycosides, and proteins (Gepts 1999, Paes et al 2000, Sakthivelkumar et al 2013.…”

Resistant genotypes are a valuable tool in integrated pest management programs of insect pests of stored grains. Here, we screened 90 Brazilian common bean genotypes to select promising sources of resistance to Acanthoscelides obtectus. Thus, bean samples were infested with newly emerged insects, and the number of eggs, emerged insects, developmental time, and larval viability were assessed in a no-choice test.
