<div style="text-align: justify;">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&rsquo;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 S&eacute;ville, 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 85.8&igrave;g/&igrave;l. 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.</div>

<div style="text-align: justify;">Quarantine examination of 13,29,901 imported seed samples of various crops during 1999- 2014 revealed presence of exotic bruchids commonly called seed or pulse beetles in 2,819 samples which were detected by X-ray radiography. Thirteen exotic bruchid species viz., Acanthoscelides desmanthi in Desmanths spp. from Colombia, A. obtectus in Phaseolus vulgaris from Argentina, Colombia Mexico, Peru; Bruchidius atrolineatus in Vigna unguiculata from Nigeria; Bruchus affinis in Vicia faba from Afghanistan; &nbsp;B. dentipes in Vicia spp. from Afghanistan, ICARDA (Syria) and Syria; B. ervi in Lens spp. from Afghanistan, Chile, Cyprus, Ethiopia, Germany, Greece, ICARDA (Syria), Iran, Iraq, Italy, Jordan, Lebanon, Mexico, Morocco, Russian Federation, Syria and Turkey; B. nubilis &nbsp;in V. faba from Ukraine; B. rufimanus in V. faba from Afghanistan, Canada, Spain and Syria; B. signaticornis in L. culinaris from ICARDA (Syria); B. tristis in Lathyrus odoratus from ICARDA (Syria); B. tristiculus in V. narborensis from Portugal; Callosobruchus rhodesianus in Vigna unguiculata from Nigeria and C. subinnotatus in V. subterranea from Ghana were intercepted. Many of the pulse beetles were intercepted repeatedly from the same/ different source(s) year after year. All the infested samples were salvaged using suitable disinfestation treatments. None of the intercepted beetles are yet reported from India, and are therefore, of high quarantine significance.</div>
