Callosobruchus chinensis é unha especie común de escaravellos crisomélidos da subfamilia Bruchinae, que é unha praga dos lugares onde se almacenan moitos tipos de legumes. Callosobruchus chinensis (Coleoptera: Bruchidae) is the main pest of mungbean (Vigna radiata) especially during seed storage.To provide background information for chemical ecology studies, we examined the externalmorphology of the antennal, maxillary palp and labial palp sensilla of this insect with scanning electron microscopy. The comparative morphology, specific status and host compatibility of two geographical strains of Callosobruchus chinensis L. (Coleoptera, Bruchudae). Adult Callosobruchus beetles do not feed on stored produce, and are very short-lived, usually no more than 12 days under optimum conditions.During this time the females lay many eggs (C. chinensis up to 70), although oviposition may be reduced in the presence of previously infested seeds (Chavan et al., 1997; Parr et al., 1998a,b).

Copyright © 1968 Published by Elsevier Ltd. https://doi.org/10.1016/0022-474X(68)90004-0. Rapid evolution has led to a large diversity in the sizes and morphology of male genitals across taxa, but the mechanisms driving this evolution remain controversial.

Status: Occasional and scattered records related to imported/stored pulses plus a few 'wild' records on umbellifers. The israeli strain had the male antennae strongly serrate, golden pubescence on the anterior part of the prothoracic median lobes, and the hind femora completely testaceous. Strains of Callosobruchus chinensis (L.) from Israel and Japan which had been in culture for several years were compared. The comparative morphology, specific status and host compatibility of two geographical strains of. When freshly moulted IV and V instar larvae of Callosobruchus chinensis were treated with different concentrations of Vitex negundo and Allium sativum oil affected the mortality, moulting and metamorphosis variedly. Callosobruchus chinensis is reported for the first time from wild host legumes in Okayama, Japan, in 1985. No evidence of intra-strain preference in mating was obtained. The evidence indicates that C. chinensis does not present a hazard to soybean production, but the genetic nature of the Israeli strain may have economic implications. Res., 1968, Vol. By continuing you agree to the use of cookies. An evaluation of the known chemical composition of soybean was undertaken and by compounding artificial beans and attempting to breed C. chinensis in them, further evidence on the incompatibility of the species with this legume was obtained. Printed in Great Britain. Attempts to breed both strains on a number of soybean varieties failed, but the Israeli strain showed partial larval development although none reached pupation. [1] [2] Esta especie ten un estilo de vida e hábitat moi similar á de Callosobruchus maculatus e é moi fácil confundilos. Taxonomic placing: Insecta, Holometabola, Coleoptera, Chrysomelidae. Callosobruchus chinensis Linnaeus. Callosobruchus chinensis (L.) is a serious pest of the stored seeds of Cicer arietinum (chickpea), C. gigas, Phaseolus spp. Callosobruchus chinensis is a very serious stored pest, causing enormous damage to almost all kind of pulse grains. To determine the wild host range in the field, the ripe pods of 15 common species of wild legumes were collected in Okayama and rearing experiments on these beans were carried out in the laboratory. These oils were found to suppress the population of pests at higher dosages, while lower dosages were found to induce several developmental defects. Habitat: Usually storage facilities, possibly outdoors nearby or on umbellifers The main morphological differences were that the Japanese strain had the male antennae pectinate, the pubescence of the median lobes of the prothorax completely white, and a dark patch on each of the hind femora. including P. aureus (radiatus) and P. aconitifolius, Lens esculenta (lentil), Pisum sativum (pea) and Dolichos biflorus throughout north-western India. In this study, we investigated the function of male genital sclerites in the adzuki Copyright © 2020 Elsevier B.V. or its licensors or contributors. [3]Este escravello está distribuído nas rexións tropicais e subtropicis do mundo. To determine the wild host range in the field, the ripe pods of 15 common species of wild legumes were collected in Okayama and rearing experiments on these beans were carried out in the laboratory. In this study, we investigated the function of male genital sclerites in the adzuki (In the past the pest was erroneously placed in the family Bruchidae).. Common name: Adzuki bean weevil, pulse beetle.. Geographical distribution: World-wide.. Morphology: The female is about 3-3.5 mm in length; the elytra are red-brown with yellow makings, antennae and legs yellow, … Journal of … The azuki bean weevil, Callosobruchus chinensis L., is one of the most serious stored product pests in the world. Callosobruchus chinensis. 135-146. This was compared with the breeding rate of Tribolium castaneum, an insect known to be insensitive to the extremes of protein and carbohydrate concentration as are found in soybeans.
