Abstract

The present study was conducted at El-Hashatra village, Yousf
El Sedek district, Fayoum governorate for 33months. Chlorozan 48%
and Helban 48% were tested against the subterranean sand termite P.
hybostoma; the active ingredient of each is chloropyrifos. A building
of 5 rooms was chosen for experimentation. The room represented a
replicate. Corrugated cardboard traps were used for 3 months to
determine foraging activity. In a complete randomized design, a dose
of 4L/trench 2% aqueous emulsion was used. Five treatments were
applied in each room; two treatments for Chlorozan being one
beneath earthen floor and the other beneath cement slab. For Helban
termiticide similar treatment was applied. Control treatment (5
trenches) received only 4L water/ trench.
Results showed that infestation varied and indicated the
efficiency of these termiticides for controlling termites. The least
number of infested traps was recorded in soil treated with Chlorozan
beneath cement slab followed by soil treated with Helban termiticide
beneath cement slab then soil treated beneath earthen floor compared
with control treatment.
Helban was less effective when applied beneath earthen floor,
where complete protection was for 6 months, whereas in treated soil
beneath cement slab 100% protecting was for 14 months. Chorozan
results showed more stable effects. The full protection was extended
to 15 months in treated soil beneath both earthen floor and cement
slab.
Chemical analysis of treated soil after 33 months indicated that
residues of Chlorpyrifos in Helban beneath earthen floor was 0.03 -
2.4 ppm and that beneath cement slab was 0.04 - 68.0 ppm. The
residues with Chlorozan treatments ranged between 0.07 - 123.0 ppm
in earthen floor and 0.65-185.0 ppm in that beneath cement slab. The
lowest concentration of Chlorpyrifos that gave protection from
subterranean termites infestations was 13.3ppm.
