“…Additionally, spotted broad bean greatly reduced the weight of emerged adults of Z. subfasciatus (Fig 2B), making it the most antibiotic genotype tested. Previous work has also demonstrated that different cultivars of cowpea can alter the damage caused by another bruchidae (Callosobruchus maculatus [Fabricius]), reducing insect emergence and population growth, and increasing mortality (Torres et al, 2016). Hence, the cowpea genotype used in this work must have been unsuitable to Z. subfasciatus development the same way that the cultivars BRS Tapaihum and BRS Acauã were to C. maculatus.…”

During storage, beans can be infested with many insect-pests including Zabrotes subfasciatus, a key pest of these crops. This study aimed to identify bean genotypes demonstrating antixenosis and/or antibiosis to Z. subfasciatus and to test their integration with chemical control. The ultimate goal of assessment was to distinguish whether genotypic and insecticidal factors can provide effective beetle control. The tested genotypes were (a) Phaseolus vulgaris group: CCB, BSCB, BCB and PCB; (b) Vicia faba group: YBB, WBB and SBB; and (c) Vigna unguiculata group: C and GC. Initial assays were run to select genotypes (without insecticide treatment) that would be further tested with insecticides. Final assays included genotypes with varying degree of antibiosis and antixenosis treated with a neem formulation (Natuneem®) and distilled water (control) plus deltamethrin (Decis®) which latter was used only in the final antibiosis assay. The insecticides were used at the rates of 3 and 0.1 mL of Natuneem® and Decis®, respectively, per 30 mL of distilled water. There were no differences in preference of Z. subfasciatus adults among non-treated genotypes (initial assays), although neem-treated genotypes altered the preference and reduced infestation from 40.54-100% (final assays). In antibiosis tests, oviposition and density of emerged adults were reduced among C and SBB, and SBB also reduced the weight of emerged adults. Insecticides reduced oviposition in 53-100% and yielded half to five-fold fewer emerging insects weighting 35%-40% less in antibiotic genotypes. SBB was the most antibiotic genotype and this and other genotypes possessing antibiosis had a synergistic effect with neem or deltamethrin.

“…Antixenosis (non-preference) resistance is the characteristic exerted by a host plant or seed to prevent the insect pest from using it for oviposition (egg-laying), feeding and shelter or all three (Dent, 2000). Other authors showed in their study that the damage caused by C. maculatus on cowpea grains is dependent on the plant genotype (Torres et al, 2016). In the study of Torres et al (2016), it was evaluated the population of C. maculatus reared on beans from four cowpea cultivars.…”

“…These cultivars" reactions toward C. maculatus indicated antixenosis resistance against this insect. Indeed, inoculation of BRS Acauã cultivar with the diazotrophic bacterial strain BR 3299 resulted in higher mortality of C. maculatus (Torres et al, 2016). The result of the screening of 50 cowpea genotypes resistance to C. maculatus (de Castro et al, 2013) showed that seven cowpea genotypes: IT85 F-2687, MN05-841 B-49, MNC99-508-1, MNC99-510-8, TVu 1593, Canapuzinho-1-2, and Sanzi Sambili exhibited non-preference-type resistance for the oviposition and feeding of C. maculatus.…”

Cowpea [Vigna unguiculata (L.) Walp.] is an important food legume. This crop considered as source of dietary protein is also used as a leafy vegetable in many African countries. Its usage as food and animal fodder is focused on food security and diminishing malnutrition particularly in marginal areas. Bruchid (Callosobruchus maculatus) is the most damaging, cosmopolitan pest of stored cowpea grains especially in the tropical region. Damage caused by this pest in cowpea is irreversible, resulting in significant loss of the grains. Several management approaches including physical barriers and biological or chemical methods are used for controlling bruchid in cowpea. Considering the qualitative and quantitative damages caused by bruchid to cowpea in storage, it is important to tackle the bruchid infestation. Development of cowpea lines resistant to bruchid is the most effective, eco-friendly and durable approach to limit the losses associated with this pest. This paper presents a review of the importance of cowpea grain, the extent of bruchid damage in cowpea and the possible control measures. The advances of conventional and molecular breeding in building resistance against this cowpea pest in cowpea are also discussed highlighting the knowledge gaps and their implications. The knowledge of the status of genetic advances will inform breeders and researchers in the development of bruchid-resistant cowpea lines.

“…Study of C. maculatus –host interactions is essential to determine its host range, and so that appropriate storage can be organized for the susceptible hosts, preventing severe damage by this insect. This idea has been considered to manage C. maculatus and the susceptibility and resistance of different host cultivars were investigated to C. maculatus infestation in several previous studies 8,19–21 …”

BACKGROUND Callosobruchus maculatus (F.) (Coleoptera: Chrysomelidae) is one of the most destructive pests of stored legume seeds in many regions of the world. Evaluation of varietal resistance of host seeds to C. maculatus infestation can be useful in preventing severe damage. We studied the susceptibility and resistance of eight conventional soybean cultivars (Caspian, Kosar, L17, Nekador, Sari, Tapour, Williams and Zane) based on the oviposition preference (choice and no‐choice tests) and population growth parameters of the pest. RESULTS Compared with other cultivars tested, oviposition preference of C. maculatus was the lowest on Nekador. The developmental time of C. maculatus differed from 40.34 days on Nekador to 48.35 days on L17, and was negatively correlated with the seed protein content. Other performance measures of C. maculatus did not match the oviposition preference. Immature survival and female longevity were highest on Caspian. The intrinsic rate of increase (rm) was higher on Tapour, Nekador and Caspian than on Zane, Williams, and Kosar. A positive correlation was observed between the rm value of the pest and moisture content of the cultivars. Cluster analysis showed that cvs Nekador, Sari, Tapour, and Caspian were relatively susceptible, and cvs Kosar, Zane, Williams and L17 were partially resistant to this pest. CONCLUSION Protein and moisture contents of soybean cultivars play an important role in the development and population growth of C. maculatus, and these traits could be used to develop safe and effective management strategies for this pest on stored soybean seeds. © 2022 Society of Chemical Industry.
