dc.description.abstract | This study was conducted in Kibwezi, Eastern Ke
nya during 20 November 2002 to 04 June 2003 to
document the insects associated with sweet potatoes
(Ipomoea batatas
(L.) Lamk) and delineate the most
important pests responsible for the crop damage so that
control measures against them can be developed.
Sweet potato vines (cv Kemp) were planted in three pl
ots of 4m x 4 m, which was a major growing area of
the crop in Eastern Kenya. Infestation of the crop by
different insect species started immediately after the
crop establishment and continued for five months in
each year. More than 50 ins
ects belonging to several
orders and at different stages of development infest
ed the crop. About eight insect species caused major
damage on the crop leaves, vines and tubers. The most
destructive and important economic pest species
were sweet potato weevil (
Cylas puncticollis
Boh.) and the clearwing moth (
Synanthedon dascyeles
).
Some 21 insect species were of minor importance,
as their damaging effects were not noticeable on the
plant and they had low effects on the yield. Other th
an pests, seven insect species were found to be
beneficial as predators or parasitoids of the insect
pests, implying that any ma
nagement practice employed
for control of the major pests should consid
er conservation of the natural enemies. | en |
