“…Both sexes feed on pollen and nectar of faba beans for 7-18 days before laying eggs. Similar results were obtained by Ikeno (1968) and Franssen (1955) on B. rufimanus Boheman, the latter reporting that 12-18 days was the period required for egg maturation in the Netherlands. The literature appears to emphasize that feeding takes place before oviposition in B. rufimanus and B. pisorum, whereas feeding during the oviposition period was found to be very important in our experiments with B. dentipes.…”

Bruchus dentipes Baudi was found to have four larval instars, and the sex ratio was very close to 1:1. Both sexes fed on pollen and nectar of faba beans (Vicia faba) for seven days before and throughout the oviposition period of the females, which was about 33 (range 26–40) days. The beginning and peak of oviposition were influenced by the phenology of the crop, particularly flowering and pod-setting dates, but also temperature. Females laid an average of 123 (range 28–310) eggs, and the end of the adult life in the field came in May when the pods had matured. In different years, peak oviposition occurred on different dates in April when the pods were still all green. During the quiescence period in the winter, females obtained from wetted seeds were fed with different diets in the laboratory, but only those supplied with faba bean flowers laid eggs. No major adult mortality occurred in seeds harvested in May and stored until the end of March of the following year, after which mortality rose steeply till all adults had died by early June. Therefore, storing seeds and delaying their planting till the following year will ensure 100% adult mortality. As the seeds remain viable, such storage is one method for reducing infestation in the field. Mortality of larvae in the stored seeds was from cannibalism when two larvae met at the same tunnel (10%), from the mite Pyemotes tritici (Lagrèze-Fossat & Montagné) (11%), from the braconid larval parasite Triaspis thoracicus (Curtis) (2%) and from unknown reasons (5%).

“…According to (Medjdoub-Bensaad et al, 2011) in the Tizi-Ouzou' region the laying activity spread over a period of one month to two and a half months. In the same vein, Franssen (1955) indicated that the duration of spawning was 17 days in 1951 and 4 days in 1954. It spaned the whole fruiting period of pods and it finished with the hardening of the pericarp and the blackening of the latter corresponding to the period of seed collection.…”

The main objective of this study is the Population dynamics evaluation of broad bean bruchid Bruchus rufimanus (Coleoptera: Chrysomelidae) in crops beans of Vicia faba within the El Asnam’s region (Algeria). A weekly monitoring of B. rufimanus was made during breeding diapauses in the laboratory and during their colonization in the parcel of variety of Séville, and then a comparative study had been implemented to characterize the total haemolymphatic protein levels during diapause and the periods of reproductive activity. The obtained results demonstrated that after the diapause period, the colonization of the field by adults of B. rufimanus coincides with the period of full bloom of the host plant which represents a trophic source necessary for the reproductive activity. 54 beetles were captured from which 28 were males. Oviposition covering a period of one month and 15 days, with a total of 168 eggs being counted, of which 72 were placed on the low layer pods. The total hemolymphatic protein content of B. rufimanus was found a high concentration during diapause and varying between 46 to 85.8ìg/ìl. High levels of protein were probably due to the stock of proteins during the larval life of this pest. Protein levels had decreased significantly in April, reflecting a recovery in the activity and colonization of bean fields for food, sexual partnership, spawning, and other activities. However, throughout the month of May, the protein concentration increased due to the pollen supply provided by the host plant and weeds present in the agrosystem.
