bassiana) and three botanical extracts; methanolic extract of Taxodium distichum leaves,
volatile oil (V.O) of Taxodium distichum leaves and (V.O) Boswella carterii (gum resin)
were studied on three stored product insects, Plodia interpunctella, Ephestia cautella and
Ephestia küehniella. At 5% concentration level to the botanical extract, T. distichum
leaves (methanolic extract), scored the highest potential effects against the target insects
(88-90% mortalities) . The other botanical extracts at this concentration causedalso high
effects (75-81 mortalities).The different stages of the target insects were affected by a
lower concentration at 0.5%. The treatments, beside inducing reasonable larval mortality,
caused increase in the malformed pupae and deformed adults. Botanical extracts tested
when combined with B. thuringiensis caused a significant enhancement to the pathogens
and increased the mortality in almost all cases. When the extract in combination with B.
bassiana caused a less than 50% reduction in the LC50 especially Taxodium distichum
(V.O).]]>Abbott, W.S.,192518265267Bowry, S.K., N.D. Pandey and R.A. Tripathi,1984Sitophilus oryzae Linnaeus.]]>46196200Burgus, H.D. and J.A.
