Red palm weevil ,Rhynchophorus ferrugineus Oliv., is one of the most important palm pests in Asia ,North of Africa and Espain.At peresent it is a qurantinius pest and very important in Iran, that it present in Saravan.Its major damages is created by larval stage.In this stage ,larva is feeding on palm bulk completely.Highest percent of infection is created on Mazafaty cultivar(%95/8).This cultivar was used for feeding in the first stage of research.Based on laboratory studies of rearing red palm weevil on natural feeds, duration of larval stage was 45-77 and 59 days on average.Mean weight of larva was 4.05 gr.Duration of pupa stage was 15-27 and 19.5 days on average. The amount of larve and pupa mortality by feeding on natural feeds were %20 and %25, respectively.life span of adults was 93 days.The number of laid eggs by female was 112 ,on average.The amount of adult creation from eggs was %59. The second step of research was perform on training of insect different stages on artifical cultures.no one of insect stages was not feeding on artifical culture,completely.
