Role of Life Table in Insect Pest Management--A Review

Abstract

Life table study is very useful to analyse the mortality of insect population, to determine key factors responsible for the highest mortality within population. It is determined by two types viz., Age Specific (or Horizontal) and Stage Specific (or Vertical) Life Table. Moreover, various mathematical formulas also indicated for the appropriate evaluation of life fecundity tables, stable age distribution and life expectancy. Life expectancy of beneficial insects can be calculated and used for biological control program by predicting natural things in particular instar within which the maximum mortality of the pests is obtained and plan for managing pests in time.
