dc.description.abstractThe red palm weevil rhynchophorus ferrugineus FABIOLIV is a very serious and dreaded pest ofcoconut, date and other palms. Being an internal feeder the weevil incidence is detected at a very late stage when the tree has succumbed to weevil attack. Hence conventional control operations may not be very effective. The biotypical variability ofthe four populations collectedfrom different parts ofIndia showed that the populations are genetically different and strainal variability exists between them. Variations in sex ratio and deleterious genetic effect were observed in the crosses and reciprocal crosses. The weevil has a very high fitness due to high production potential and the absence ofeffoctive parasites, predators and pathogens. In spite of the high fitness, in endemic areas weevil population tend to remain at certain levels ofintensity. This may be due to certain limiting factors.en_US
