Description House fly menace is one of the major problems in livestock and poultry
production. The layer farms in Namakkal district, the largest layer belt in Tamil
Nadu, are frequently confronted with fly problems. Conventional method of fly control
using chemical insecticides has inherent limitations. In the present study, the efficacy
of plant essential oils was evaluated against house flies in the laboratory and under
field condition.
Essential oils were extracted from the fresh leaves and powders of
eucalyptus, mint, lemon, lemon grass and peels of orange by hydrodistillation using
Clevenger apparatus. Essential oils were analysed by GC-MS method and major
components were identified.
Efficacy of essential oils against larvae and pupae of house flies was
evaluated at various concentrations viz., 50,100,150, and 200 ?l by in vitro methods.
The LD50 values of mixed oil, mint, lemon grass, orange, lemon and eucalyptus
against larvae and pupae were 5.89 and 21.20 ?l, 29.58 and 18.26 ?l, 33.28 and
48.27 ?l , 37.42 and 17.8 ?l, and 48.2 and 15.69 ?l, respectively.
Similarly the efficacy of plant powders was also tested against larvae and
pupae by in vitro methods. The insecticidal properties of powder were found to be
lesser than the essential oils. However, the plant powders showed high pupicidal
effect.
Fumigant toxicity of essential oils against adult flies was tested at the
concentrations viz., 50,100,150 and 200 ?l by in vitro methods. At the highest
concentration, mixed oil took 3.8 ? 0.18 minutes to cause 100 per cent mortality of
adult flies , while lemon, lemon grass, mint, eucalyptus and orange oil took 4.0 ? 0.6,
4.3 ? 0.11, 5.5 ? 0.17, 6.5 ? 0.24 and 10.5 ? 0.22 minutes, respectively. In the
control group, no mortality was observed for up to 2 days.
Fly repellent and oviposition deterrent effect of essential oils and powders
were studied on a quail farm. A highly significant difference (P
