Description Field experiments were carried out to
study the population dynamics of Lobster moth
(Neostauropus alternus Walker) on pigeonpea and
its relation with different weather variables during
kharif season of 2013-14 and 2014-15 under unprotected
conditions at Pantnagar, Uttarakhand, India.
The results revealed that the incidence of this insect
commenced from the 34th standard week and it remained
active up to 41st standard week of both the
years. The insect showed one peak of its population
during both the years. The maximum number of N.
alternus was recorded on 37th standard week (5.6
larvae per plant) in 2013-14 while in 2014-15, population
of N. alternus was highest in 38th standard week
(4.8 larvae per plant). Correlation studies indicated
that larval population of N. alternus exhibited a significant
positive correlation with temperature whereas a
significant negative correlation was established
with relative humidity. Other abiotic factors had no
significant effect on this insect pest population.
