Where as, it correlated negatively and significantly with minimum temperature at one, two, three and four weeks lead time. Similarly, it also correlated negatively and significantly with morning and afternoon relative humidities that existed during the week of observation, one, two, three and four weeks lead time. The female had three nymphal instars while the male had four. The total life cycle of grape mealy bug took more days during winter than summer.
