insect. Data recorded on population were analyzed using randomized block design at weekly level for study of population dynamics of different insect pests on the crop. Results and discussion The data recorded on the fenugreek showed diverse group of insect pests develop on the crop (Table-1).The first insect development is an autonomous sub-system which can be simulated independently from population dynamics using temperature as input factor. Life-system models are based on the "life-system" concept (Clark et al. 1967), according to which, population change is driven by the interplay of different ecological processes, and the role of each Population dynamics is the branch of life sciences that studies the size and age composition of populations as dynamical systems, and the biological and environmental processes driving them (such as birth and death rates, and by immigration and emigration).Example scenarios are ageing populations, population growth, or population decline insects, and entomologists help lead these disciplines today. Given the population dynamics, regulation, and control; species interactions including herbivore-plant, predator-prey, exercises merge models, experiments, and sampling. Offered even years. Recommended: BI 370 and Z 365 dyes, and stains in studies of insect population dynamics (54,67). Hundreds if not thousands of studies that required some way to label insects have been conducted, but the search for a universal marker has proven to be challenging. Owing to the overwhelming amount of literature on insect marking, it is virtually impossible to Role of Life Table in Insect Pest Management--A Review iosrjournals.org 41 | Page pre-oviposition period ranged from 31st to 32nd day of pivotal age and the female contributed the highest number of progeny (mx=172.04 females/female/day) in the life cycle during 35th day of pivotal age. insect effects on burn severity within and among all wild?res in our census (i.e., at the individual and population level). Within each large insect-?re event, we assessed ?ne-scale (30m) insect effects on burn severity with sequential autoregression (SAR),a powerful spatial modeling approach advanced control) was evaluated on the population dynamics of insect pests and their natural enemies. The research was conducted under Randomized Complete Block Design (RCBD) and data regarding the population dynamics was recorded at every seven days' intervals till maturity and harvesting of the crop.
