Efektivitas Insektisida Komersial Terhadap Kecoak Jerman (Blattella Germanica L.) Strain VCRU-WHO, GFA-JKT dan PLZ-PDG dengan Metode Kontak (Glass Jar)
Abstract: The purposes
of this study
was to find
out the effectiveness
of commercial insecticides
to German cockroaches. Study
was conducted from
September to November
2013 in the Laboratory of Animal Physiology,
Department of Biology, Andalas University. This study used the contact method
(glass jar) with three strains of German cockroaches (VCRU–WHO,
GFA-JKT and PLZ-PDG) and five kinds of insecticide (ByWS, HtWS, MtWS, RdWS, and
VpWS). The average of
knockdown time and
lethal time were
counted with a
probit analysis. The effectiveness category divided into two
groups, value of knockdown time and lethal time were needed to
be achieved in
a certain time.
The results showed
that based on
the value of knockdown time 90% (KT90), effective
aerosol insecticide to knockdown the German cockroach is aerosol insecticide
ByWS, HtWS and VpWS. Aerosol insecticide MtWS was only effective to knockdown
the German cockroach VCRU-WHO strain and ineffective for GFA-JKT and
PLZ-PDG strains. Aerosol
insecticide RdWS was
only effective to
knockdown the German cockroach VCRU-WHO
and GFA-JKT strains,
ineffective for PLZ-PDG
strain. Based on the
lethal time 90% (LT90) there was no
single insecticide effective to kill German cockroach.
