4 Conclusions
The treatments T4 (
Bt
proteins and
C. flavicincta
)
were more effective in controlling
S. frugiperda
, thus
indicating a potential of proteins Cry and
C. flavicincta
to be used in the control of pest an integrated pest
management system. The offspring of the parasitoids
that developed in larvae treated with
Bt thuringiensis
4412 exhibited altered biological characteristic when
compares to the control. These effects were largely
indirect, related to the sensitivity of lepidopteran
larvae to
B. thuringiensis.
. However, the existence of
direct effects cannot be excluded.
Authors'Contributions:
LP oversaw the development of bioassays and insect rearing,
helped in the analysis of results and preparation of the
manuscript. FP produced some bioassays and helped in the
creation of insects.VM helped the statistical analysis and
drafting of the manuscript, LF oversaw the development of the
tests, helped in data analysis and preparation of the manuscript.
