Abstract
Phenacoccus solenopsis
life table experiments on the okra (Abelmoschus esculentus L.) host
plant were conducted in the laboratory. The overall life cycle was completed in
53 days during the late summer (Kharif) season, according to the
findings. On the 6th day, the highest mortality (d x) was seen, while the
highest life expectancy (ex) was observed on the 25th day. The II
instar had the highest death rate (19.50%), followed by the I instar (16.50 %).
The intrinsic rate of increase was 0.188 (female/female/day), and the net
reproductive rate was 183.76 (females/female/generation). The mean generation
time was 29.47 days. The oviposition period was 23 days long. On the 4th day of
crucial age, the highest natality (53.5 eggs/ female) was reported, while the lowest
fecundity (5) was recorded on the 1st and 16th days. The study found that the
sequential arrangement of all key life table parameters led to the conclusion
that Phenacoccus solenopsis potential fecundity 405.5
eggs/female/generation and doubling time (3.68 days) with mean survival time
40.35 days were indicative of serious proportions, and thus may have a negative
impact on okra production in India.
