Acanthoscelides Obtectus Say

Acanthoscelides obtectus (Say, 1831) (Coleoptera: Chrysomelidae: Bruchinae) es unescarabajo de distribución cosmopolita que ocasiona graves daños a diversas especies de la familia Fabaceae. Este trabajo es el primer reporte de su infestación en arbustos de Senna multiglandulosa (Jacq.) H.S. Irwin & Barneby, 1982 (Fabaceae) en la zona andina central del Perú. Se describe la morfología de los estados biológicos de A. obtectus y las perforaciones que realizaron en legumbres infestadas colectadas en tres lugares del Valle del Mantaro de enero a diciembre 2018. Se midió la longitud total (L) y ancho (A) de los huevos, larvas, pupas y adultos de A. obtectus, así como el diámetro (D) de las perforaciones en vainas y semilla de S. multiglandulosa. Los resultados mostraron diferencias significativas en los tamaños de cada uno de los estadios (p < 0,001) y sus perforaciones en las legumbres (p < 0,001), afectan especialmente las semillas de S. multiglandulosa, por lo cual se constituye en un problema sanitario muy severo en la planta estudiada. Acanthoscelides obtectus (Say, 1831) (Coleoptera: Chrysomelidae: Bruchinae) is a beetle with a cosmopolitan distribution that causes severe damages to diverse species of the Fabaceae family. This is the first report of its infestation on Senna multiglandulosa (Jacq.) H.S. Irwin & Barneby, 1982 (Fabaceae) bushes in the central Andean region of Peru. The morphology of the biological stages of A. obtectus and the perforations they made on infested legumes collected in three sites of Mantaro Valley from January to December 2018 are described. The total length (L) and width (W) of eggs, larvae, pupae, and adults of A. obtectus and the diameter (D) of the perforations on the pods and seeds of S. multiglandulosa were measured. The results showed significant differences in the size of each stage (p < 0.001) and their perforations on legumes (p < 0.001), affecting mainly the seeds of S. multiglandulosa, constituting a severe health problem for the studied plant.

Acanthoscelides Obtectus Say

This paper relates a female age effect to the mating behavior of Chryseida bennetti Burks, an ectoparasitoid of the bean weevil (Acanthoscelides obtectus (Say)). The sexual behavior includes rapid courtship and copulation followed by a postmating courtship behavior ("guarding"). Male guarding behavior varies according to the females' age, with males guarding females of 2–3 days old longer than younger and older females. A period of sexual maturation is necessary for most of the males. Females' attractiveness begins at the pupal stage, and their receptivity on emergence. Mated females are still attractive to males. Multiple matings (up to four copulations) with the same male have been observed. The females' age seems to control copulation frequency and the duration of the postmating courtship behavior. Two- and three-day-old females had more successive multiple matings with the same male than the other females did, and males spent much more time guarding them. The age of the males (except from newly emerged males) did not seem to influence copulation frequency. On the other hand, the complexity of the sequential courtship behavior increased with the age of the partners. The function of males' postmating courtship is discussed.

Acanthoscelides Obtectus Say

Twenty-six mungbean varieties and accessions were screened for resistance to 4 bruchid species (Coleoptera : Chrysomelidae). On the basis of the percentage of seeds damaged all Australian commercial mungbean varieties tested here were highly susceptible to strains of Callosobruchus maculatus and C. chinensis, the 2 species that cause most damage worldwide to mungbean in storage. In addition, 3 accessions of wild mungbean appeared to have bruchid resistance. The texture layer present on the seed coat of some mungbean varieties and small seed size may act as oviposition deterrents. Consequently, these assays for determining resistance to bruchid infestation may not be suitable for identifying biochemical resistance of some mungbean genotypes.
