Los brúquidos se alimentan principalmente de semillas de leguminosas, entre las cuales se encuentran algunos cultivos de importancia económica como el frijol (Phaseolus vulgaris L.), garbanzo (Cicer arietinum L.), lenteja (Lens culinaris Medik) y tamarindo (Tamarindus indica L.) entre otros, considerando al primero como la fuente principal de proteína en la dieta humana; sin embargo, Vigna unguiculata (L.) Walp, por sus propiedades nutritivas podría sustituir al frijol, pero su principal problema es la presencia de plagas, en particular los brúquidos, los cuales ocasionan pérdidas  considerables en postcosecha, por lo que fue necesario conocer los parámetros poblacionales de Acanthoscelides obtectus (Say, 1831), Callosobruchus maculatus (Fabricius, 1775) procedente de dos hospederos diferentes y Zabrotes subfasciatus (Boheman, 1833) alimentados con V. unguiculata por medio de un estudio demográfico bajo condiciones controladas. Los parámetros poblacionales se estimaron con la técnica de tablas de vida de cohorte, la prueba de Log rank (p ≤ 0.05) y las tasas de reproducción e intervalos de confianza con la técnica no paramétrica de Traslape de Intervalos (p ≤ 0.10), para comparar tasas instantáneas de reproducción (rm), llamada también capacidad innata de incremento. Estos parámetros poblacionales fueron mayores en la emergencia de los adultos y tasas de reproducción de C. maculatus en sus dos modalidades por lo que esta especie puede ocasionar serios problemas cuando se presenta asociado con V. unguiculata; sin embargo, A. obtectus y Z. subfasciatus sólo si no tienen opción podríanalimentarse de V. unguiculata en condiciones de almacenamiento.

Endosperm Formation

The formation of the endosperm in Phaseolus vulgaris L. conforms to the nuclear pattern of endosperm development. The endosperm is partially cellularized in the vicinity of the developing embryo, while the rest of the endosperm remains multinucleate. Mitotic activity of the endosperm is gradually confined to the region adjacent to the tips of the enlarging cotyledons. Continuing mitotic activity in this region results in the formation of cellular endosperm in the bean seed. At the cotyledon stage of embryo development, except in the region of the degenerating nucellus, the entire surface of the developing embryo is covered by a layer of cellular endosperm cells. Initially, the cellular endosperm is loosely attached to the inner surface of the seed coat. With the disappearance of the liquid endosperm, it becomes firmly attached. Further expansion of the seed results in the separation of cellular endosperm cells along their long axes. As the seed matures, the cellular endosperm dries, with no apparent degradation of its cells.

We have confirmed here that the seeds of the common bean (Phaseolus vulgaris, L.) do not support development of the bruchid Callosobruchus maculatus (F.), a pest of cowpea [Vigna unguiculata (L.) Walp] seeds. Analysis of the testa (seed coat) of the bean suggested that neither thickness nor the levels of compounds such as tannic acid, tannins, or HCN are important for the resistance. On the other hand, we have found that phaseolin (vicilin-like 7S storage globulin), detected in the testa by Western blotting and N-terminal amino acid sequencing, is detrimental to the development of C. maculatus. As for the case of other previously studied legume seeds (Canavalia ensiformis and Phaseolus lunatus) we suggest that the presence of vicilin-like proteins in the testa of P. vulgaris may have had a significant role in the evolutionary adaptation of bruchids to the seeds of leguminous plants.

Abstract. Beans are a staple component of human diet. However, grain storage for consumption is difficult due to pest attack. The objective of the present study was to conduct a survey of insects acting on the beans Phaseolus vulgaris L. and Vigna unguiculata (L.) in commercial stores in Porto Velho, Rondônia, Brazil. Samples were collected in small, medium-sized, and large markets. Percent infestation and weight loss caused by insects was evaluated during nine weeks. For V. unguiculata, 3.70% infestation was recorded from store PT 7 and the medium-sized market; the most serious situation occurred on the fifth week, when infestation reached 2.93%; weight loss was recorded from PT2 and PT7, with 19.19 g and 23.57 g. For P. vulgaris, infestation reached 3.70% in material from PT6; in small markets, infestation attained 0.84%; on the ninth week, 1.29% was recorded; weight loss from insects infestation occurred in samples from PT1 and PT6, 18.50 g and 9.78 g. Insect species found were Callosobruchus maculatus (Fabr.), Zabrotes subfasciatus (Boh.) and Acanthoscelides obtectus Say. Insect infestation did not significantly differ between both bean species.Levantamento dos Insetos que Atacam os Grãos de Feijão Armazenado Vigna unguiculata (L.) e Phaseolus vulgaris L.em Porto Velho, Rondônia, BrasilResumo. O feijão é um componente fundamental na alimentação dos seres humanos. Entretanto, o armazenamento dos grãos para consumo se torna uma enorme dificuldade devido ao ataque de insetos. O presente estudo teve como objetivo realizar um levantamento de insetos que atacam feijão armazenado Phaseolus vulgaris L. e Vigna unguiculata (L.) em estabelecimentos comerciais de Porto Velho, Rondônia, Brasil. As amostras foram coletadas em mercados de pequeno, médio e grande porte, nas quais foi avaliado o percentual de infestação e perda de peso ocasionado pelos insetos durante nove semanas. Para V. unguiculata PT 7 registrou 3,70% de infestação, o mercado de médio porte atingiu 3,70%, a 5ª semana foi a mais agravante alcançando 2,93% de infestação, já a perda de peso ocorreu em PT2 e PT7 sendo 19,19 g e 23,57 g. Para P. vulgaris a infestação em PT6 chegou a 3,70% , em mercados de porte pequeno a infestação resultou em 0,84%, na 9ª semana observou-se 1,29%, em relação a perda de peso por infestação de insetos ocorreram em PT1 e PT6, sendo de 18,50 g e 9,78 g. As espécies de insetos encontradas foram Callosobruchus maculatus (Fabr.), Zabrotes subfasciatus (Boh.) e Acanthoscelides obtectus Say,em ambas as espécies de feijão não houve diferença significativa em relação as infestações pelas pragas.

As part of working on the solution of the task of importing asparagus beans, it is necessary to create a conveyor of green beans for vegetables during the growing season under the conditions of the Central Nonchernozem Zone (CNZ). In this regard, in 2018, work was continued on the evaluation of the existing collection of the FSBSI FSVC on economically valuable grounds, which allowed pre-select promising samples for further breeding work. According to the results of the assessment of the collection variety samples of vegetable beans in 2018, 30 variety samples of different groups of ripeness were identified as initial forms for breeding work on creating varieties that meet the requirements of the processing industry and creating a conveyor for producing asparagus products in the CNZ. Selected varieties are described and evaluated for the productivity of beans and seeds, suitability for mechanized harvesting, quality of the bean, seed size, resistance to the most harmful diseases. It is important to note that the year 2018 was unfavorable for the optimal development of culture due to the negative weather conditions that developed from the 3rd decade of May to the 2nd decade of June. This has made its own adjustments to the development of plants, as a result of which the assessment on some grounds is not indicative.

The in vitro synthesis of phytate was studied in common bean fruit explants. Different concentrations of sucrose; phosphorus (P); myo-inositol; abscisic acid (ABA); glutamine and methionine, were tested. Fixed concentrations of these compounds were tested at different periods (0, 3, 6 and 9 days). Variation in phytate coincided with different concentrations of sucrose, myo-inositol, P and ABA for the duration tested. These compounds caused an accumulation of phytate and were more effective in the presence of myo-inositol and P. The accumulation of P varied less than phytate for the different treatments tested in vitro. In conclusion, P, sucrose, ABA, and myo-inositol caused an increase in the phytate of bean seed, showing that it could be possible to alter its content by culturing bean fruit explants in vitro.
