ABSTRACT
Exotic Paulownia fast growing tree species of Chinese
origin were introduced in different ecological zones of
Pakistan. Studies conducted by recording the
observations fortnightly on nurseries and plantations at
the Pakistan Forest Institute Campus, Peshawar showed
that the Paulownia spp. Fell prey to the attack of
fourteen insect species like Agrotis ypsilon Rott.
(Noctuidae), Aleuroplatus pectiniferus Quiint.
(Aleyrodidae), Catopsilia crocale Cram. (Pieridae),
Cyrtopeltis tenuis Reut. (Miridae), Drosicha stebbingii
Gr. (Margarodidae), Heliothis armigera Hueb.
(Noctuidae), H. peltigera Hueb. (Noctuidae), Lumantria
sp. Walk. (Lymantriidae), Nyzus persicae Sul.
(Aphididae), Odontotermes obesus Ram. (Termitidae),
Plusia orichalcea Fab. (Noctuidae), P. nigrisigna Fab.
(Noctuidae), Phycodes radiate Ochsen. (Glyphipterygidae)
and Precis orithya Marsh. (Nymphalidae). Among these
insect species D. stebbingii appeared in epidemic form
on Paulownia tomentosa and P. fortunei. The pest was
managed by adopting integrated control strategy in which
practices like destruction of eggs by soil working,
banding of tree trunks and application of insecticides
were combined together. All the components of integrated
control strategy proved effective. Among the chemicals
Buldock 25EC, Mepra 50EC and Endon 35EC @ 0.2% were the
most effective insecticides against the pest.
