| dc.description.abstract | The insecticidal activity of
Maruca vitrata
(F.) multi-nucleopolyhedrovirus (
Mavi
MNPV) combined with
oil from neem,
Azadirachta indica
Juss and
Jatropha curcas
L. (Euphorbiaceae) was studied under labo-
ratory and
fi
eld conditions against three key insect pests of cowpea,
Vigna unguiculata
(L.) Walp. Second-
instar
Aphis craccivora
Koch and
Megalurothirps sjostedti
Trybom nymphs, and third-instar
M. vitrata
larvae, all from laboratory colonies, were treated with various concentrations of one of the control agents
separately or combined. Daily mortality was recorded for
fi
ve days (
A. craccivora
and
M. sjostedti
nymphs)
or fourteen days (
M. vitrata
) and the larval and pupal development as well as adult emergence were
assessed. Combination of
Mavi
MNPV resulted in a signi
fi
cantly higher larval mortality in
M. vitrata
than
treatment with either virus or botanical insecticide alone at the corresponding concentrations. Larvae of
M. vitrata
infected with
Mavi
MNPV and treated with botanical oils died sooner than those infected with
only one control agent. Combinations of
Mavi
MNPV and botanical oils produced additive or synergistic
effects. No evidence of antagonistic effects was noted. In
fi
eld experiments, the application of botanical
insecticide and
Mavi
MNPV either alone or in combination was effective in reducing insect abundance
over the four weeks, and preventing yield loss. In the
fi
rst
fi
eld season, where the
M. vitrata
population
was higher, the combination of the virus and either of the botanical pesticides induced signi
fi
cantly
higher yields than spraying chemical insecticide. Application of
Mavi
MNPV in combination with
J. curcas
and
A. indica
oil has proven to induce consistent
Mavi
MNPV infection in
M. vitrata
populations. The
combined application of
Mavi
MNPV and botanical oils is discussed in the context of integrated pest
management.The insecticidal activity of
