In 1988 Dengue Haemorraghic
Fever had spread to 27 provinces
in Indonesia. Drugs or vaccines
against the disease have not
been found yet; hence an alter-
native to break the chain of trans-
mission is an intensive Aedespre-
vention and control,
Plant-larvicides and organisms
that can be used for Aedeslarvae
control should be developed.

A trial of Malathion 96 EC (dose
500 ml/ha) against Aedes aegypti
larvae has been carried out.
Fogging was conducted in the
morning using Fontan in human
habitation of the Ngawen Tegal-
sari village, Salatiga Municipality,
in 1996.
Air bioassay test showed that
Malathion 96 EC was effective
against Ae. aegypti larvae in
open area (80100%) and in
containers with various diame-
ters (310 cm)in bushes (6084%).

CORRELATION BETWEEN MESO-
CYCLOPS ASPERICORNIS' LENGTH
AND PREDATION POTENTIAL
TOWARDS VECTOR LARVAE

Mesocyclops aspericornis is
presently cultured and inves-
tigated in the Vector Control
Research Station. Its predation
potential towards mosquito
larvae is presently studied in re-
lotion to its size. Length sizes cate-
gorizedato 0.5,0.8,1.1, 1.3 and 1.7
mm exposed to larvae at 24, 48
and 72 hours, showed a preda-
tion rate of approximately 88%
100% on Aedes aegypti larvae.
Length sizes of 0.5 and 0.8 mm
showed a low predation rate of
less than 50% on Culex quinque-
fasciatus larvae during 24,48 and
72 hours of exposure. A predation
rate of more than 50% was de-
tected in M. aspericornis measur-
ing 1.1 mm or more.
Length sizes of 0.5, 0.8 and 1.1
mm showed a low predation
rate (less than 50%) on Anopheles
aconitus larvae during 24, 48 and
72 hours of exposure. Percentage
predation of more than 50% was
detected in M. aspericornis
measuring 1.3 mm exposed for
72 hours and 1.7 mm on all expo-
sure periods.
Mesocyclops aspericornis
shows a potential for further de-
velopment as a biological
agent.
