Abstract. The present research was aimed to study the biology of Caryedon serratus (Olivier) on groundnut,. Arachis hypogaea (L.) under. C. serratus infestation of groundnuts is revealed by larval emergence holes and the presence of cocoons outside the pods. Feeding damage to the seeds can be . Higher rates of infestation by the larvae of the seed weevil Caryedon serratus Olivier (Col., Bruchidae) were recorded. The larvae of C. serratus bore into the.

The pest damages peanuts as well as tamarinds. Several parasitoids attack the pest in Acacia pods, including the pteromalid Anisopteromalus calandrae Howard. The plant materials used were from several host plants families.
Characteristics of groundnut specimen used. The results of pre-oviposition, oviposition serrratus post-oviposition duration are presented on Table 3. The number of adult insects emerged varied from 7 to according to host plants. However, some females spent less than 24 hours to lay their first eggs while for others, this period was 6 days. Bruchidae from the Middle East.
To determine the pre-oviposition period, same age Serrahus. All the experiments were carried out with seeds belonging to various leguminous plants. After laying period, an average time of 4. In all of the tested host plants, the larval development of the beetle was possible on only five host plants.
After this stage, some larvae according to feeding support availability may infest new seeds. Conflicts of Interest The authors declare no conflicts of interest. Small openings are made on the bottle and are covered with a close mesh-net cloth to allow air circulation.
Table 3 indicates that females spend on average 1. For these authors, F. Samenkaefer, Westafrikanischer Erdnuss- Sergatus The incubation period of eggs is similar to that reported by Robert  but it is the half of what was reported by Rama and Venugopal  who found an incubation time of 8 days. Damage potential and loss caused by the groundnut bruchid Caryedon serratus Olivier [Coleoptera: Cite this paper Ouedraogo, I.
Growth Stages Top of page Post-harvest. The average length for insects emerged from two-seeds pods was 6. Bruchidae in Northern Nigeria, with a list of associated parasitic Hymenoptera. Serrarus Most popular papers.
Datasheet Caryedon serratus groundnut bruchid. In spite of a growing production, groundnut remains out of the reach of consumers at some periods of the year.
In Sahelian countries in general and Burkina Faso in particular, groundnut is one sserratus the most cultivated and consumed leguminous plant. Pod type influence on Caryedon serratus various biological parameters.
Groundnut is attacked by several insect pests during storage which cause important losses    . The results on the development time show the importance of the laying substrate on larvae development.
On seeds exposed to C.

Studies were carried out on the laying behavior of C.
The paper is not in the journal. The groundnut seed beetle, a study of its identity and taxonomic position. Journal of Asia-Pacific Entomology, 16, Thus, during the dissection of a groundnut seed, the presence of a cephalic cell is sought to mean that the larva moved from serrqtus stage to another.

Seed Research, 35 1: The beginning of the emission of the first egg determines the pre-oviposition period and the post-oviposition is the period which separates the emission of the last egg and the female death.
Infestations cause reductions in food value, in the quality of the oil and in reduced seed germination.
