The research was conducted in Al- Mokhtaria Research
Station, Agricultural Research Center, Homs, Syria during season
2016. The efficacy of some plant extracts (Melia azedarach L.,
Schinus molle L., Styrax officinalis L., Eucalyptus camaldulensis
De., Nerium oleander L.) were tested against Stephanitis pyri F.
(Tingidae: Heteroptera) and compared with traditional insecticides
(Cypermethrin, Chlorpyrifos Ethel).
The efficacy of insecticide and plant extracts were tested against beet flea
beetle, Chaetocnema tibialis (Illiger) during 2008 and 2009 seasons. Six
pesticides were evaluated against beet flea beetle, results showed that Cyperino
gave the highest
effective percentage (90.88) followed by Cypermethrin
(90.69%), in comparison with Nimadol (49.35%) after two weeks of treatment.
Four plant extracts were evaluated against beet flea beetle in comparison with
Sopreen. Results showed that Melia azedarach L. extract gave the highest
effective percentage (60.81) followed Styrax officinalis L. leaves and branches
and Capsicum annuum L. extracts by 31.35, 28.44 and 16.57, respectively, in
comparison with Sopreen (58.55%) after 7 days of treatment. Percentage of
efficacy decreased gradually by increasing the period of exposure after
treatment for plant extracts from 63.19% after 3 days to 51.80% after 10 days
of Melia azedarach L. extract. Whereas the efficacy percentage of Sopreen
increased from 41.67% after 3 days to 74.57% after 10 days of treatment.
The side-effect of six insecticides get to be used on apple trees in Syria were
tested on the adults of the egg parasitoid Trichogramma cacoeciae Marchal.
Using the exposure of adults to treatment glass plates for 24 hours. The highest
recommended
field application rate was applied. The classification of the
International Organization for Biological Control for insecticides effect in
adults mortality or reducing of parasitism was used (1, Harmless; 2, slightly
harmful; 3, moderately harmful; 4, harmless). This study showed that
Cloropyrifos, Deltamethrin and Acetamiprid and caused adults mortality
100%, and classified as harmful insecticides (glass 4) according to IOBC. While
Diflubenzuron, lufenuron and fenoxycarb were slightly harmful in adults
mortality (class 2) according to IOBC. Whereas was harmful to larval stage
only, and moderately harmful to the egg and pupae. Acetamiprid was also
harmful to the egg stage and moderately harmful to larvae and pupae. Whereas
the insect growth regulator insecticides and the insect growth inhibitors
(Diflubenzuron, Lufenuron and Fenoxycarb) caused reducing in parasitism
(82.05, 56.03, 94.40)% for the three insecticides respectively, and classified
(class 2, 2, 3) respectively according IOBC category compared with the
parasitism in control 89.25%, also the latest three insecticides reduced
significantly the longevity of adults which were survived after the exposure to
treatment class plate compared with the control.
This research has been applied to compare the efficacy of the use
of pre-planting with a sensitive variety of tomato OXN93 as a trap
crop with the use of the extracts of M. azedarach , E.
camaldulensis and C. maculatum where Diazinon a treated con
trol,
in reducing the infection and the reproduction rate of the root-knot
nematodes M. javanica on tomato (var. Bestona) in pots.
This study was conducted in order to evaluate the efficacy of the aqueous extracts
of three plants (Melia azedarach L., Smilax asepra L. and Styrax officinalis L.),
three pesticides (acetamiprid, abamectin and pyridaben) and releasing of two
preda
tors (Phytoseiuls persimilis Athias–Henriot and Stethorus gilvifrons Mulsant)
in controlling of Tetranychus urticae Koch populations in tomato greenhouse.
