continues to be encouraged to reduce the use of
insecticides that have an impact on the environment.
Biological control using Bacillus thuringiensis bacteria
local indigenous isolates continues to be developed in this
study the toxicity test of local isolates ABNP 8, 9, 11 and
12 on the larvae of Anopheles mosquito at the Faculty of
Mathematics and Sciences, Cenderawasih University.
The aim of the study was to determine the toxicity of 8, 9,
11 and 12 local ABNP isolates and to obtain local
indigenous isolates with toxicity = 85% to Anopheles
mosquito larvae. The method used was experimental with
a completely randomized design pattern using 4 local
isolates, the course of the study was made of 50 cm deep
grooves, 40 cm in diameter given transparent plastic and
10 L of water with a height of 30 cm and then sprayed
with 100 mL isolate culture. Each typical mosquito plastic
containing 40 instar 2 Anopheles larvae each treatment
isolate was repeated 3 times, observations were made
after 72 h by counting the number of dead Anopheles
larvae. The results showed the toxicity of local ABNP 8
isolates (73.33%), 9 ABNP, (74.17%), 11 ABNP, (73.33)
and 12 ABNP, (98.33%) and variance analysis showed
that the isolate treatment differed significantly at the
level of 05%, further testing using BNt α0.05,
obtained by BNt value 9.24. The results of variance
analysis with BNt further tests showed the treatment of
local isolates of B. thuringienis ABNP 8, 9 and 11
toxicity was not different from the death of Anopheles
mosquito larvae this could be caused by several factors,
namely the possibility of ABNP 8, 9 isolate and 11
bacterial strains were the same by sex influential in
metamorphosis. Whereas local B. thuringiensis ABNP 12
isolates with a toxicity of = 85%, are much higher than
ABNP 8, 9 isolates and 11 may be caused by differences
in toxicity and strains against the death of Anopheles
larvae, considering B. thuringiensis based on current
serological tests obtained 58 strains with toxicity different
or specific to insect larvae.}
