Ans.)The warm, moist conditions and copious nourishment in a nursery give a superb, stable environment for pest advancement. Generally, the characteristic adversaries that serve to monitor bugs outside are not present in the nursery. For these reasons, pest situations often extend in this environment and with greater severity than outdoors.. Bother issues can be unending unless perceived and adjusted. There are several methods are determine the amount of additive genetic variation in resistance to individual insecticides and subsequent estimation of the heritability (h2) of resistance. Heritability is the degree of difference in a specific characteristic, in a specific populace, that is because of hereditary variables, instead of ecological impacts or stochastic variety. Broadly there are two types of heritability; Broad and narrow H2 = Broad sense heritability h2 = Narrow sense heritability Here H2 = Vg/Vp where, Vp ( phenotypic var) = Vg (genetic var) + VE (environmental var) Solution Ans.)The warm, moist conditions and copious nourishment in a nursery give a superb, stable environment for pest advancement.
