ABSTRACT
This study was conducted during 2004 and 2005 seasons to
investigate the efficiency of some integrated bird management on
controlling house sparrow birds and improving quality of
Thompson seedless grapes. Four chemical pesticides namely
Pyriban, Cidial L, Captan and Bayfidan, were used. Two birds
scaring namely nylon fish nets and reflecting stripes were also
tested.
Results showed that using pesticides at 0.5 to 1.0% in
Thompson seedless vineyard achieved considerable protection
against house sparrow birds compared to the check treatment. The
degree of protection was associated with increasing the level of
application. The highest repellency effect against the house
sparrow birds was occurred with using Pyriban and Bayfidan in
the first season and Captan and Bayfidan in the second one.
Application of Bayfidan proved to be effective in both seasons.
Using Nylon fish nets and reflecting stripes caused a great
protection against house sparrow birds. Reflecting stripes as bird
scaring was preferable than Nylon fish nets in protecting the fruits
from the birds. Application of the four pesticides namely Cidial-L,
Captan Pyriban and Bayfidan at 0.5 to 1.0, in the descending order
effectively improved quality parameters of fruits in terms of
increasing weight size and dimensions of berry, total soluble solids
% and T.S.S / acid ratio and in reducing total acidity. Berries of
the treated vines tended to be roundish. The promotion was
associated with increasing rates of concentration.
Sh. M. Abd EL-All et. al.
According to the methods of bird management which have
the least impact on ecosystems stability and natural balance; it is
recommended to use reflecting stripes as bird scaring for
alleviating damage caused by house sparrow birds in Thompson
seedless vineyards.
INTRODUCTION
Grapes are the most widely distributed fruit crops. They are the
most important fruits due to their high production which give a great
net income to growers. In 2003, the total area cultivate with
grapevines in Egypt was more than 155000 feddans (according to the
last statistics of Ministry of Agriculture, 2004).
Bird damage problem all-over the world is of great concern,
since the economic losses caused by birds reached more than 10% of
the production in different crops (Bruggers and Ruelle, 1981). Total
losses in grape production in the world due to bird damage reached
several millions of dollars annually (Dehaven et. al. 1979). Egypt
suffers from considerable production losses from flying vertebrates.
However, controlling of birds is considered the most difficult
operation because many birds are protected by international laws.
Bird repellent methods are safe for the environment and for non
target and even target species. Their functions are usually based on the
physical and chemical senses of target pests and crops (Fitzwater,
1982). Methods of bird repellent are classified into the following
groups: a) visual repellents (through light), b) acoustical repellent
(hearing), c) tactile repellents (touch), d) gustatory repellent (taste)
and F) olfactory repellents (smell). A good repellent methods on
material is the are that affects two or more these senses. Therefore,
application of pesticides to control of the noxious bird species (i.e.
house sparrow, Passer domesticus niloticus and Spanish sparrow and
Passer Paniolensis) on vineyards was accompanied with improving the
yield and quality of the fruits. These integrated bird management
applied in vineyards was followed by improving productivity (Winkler
1953; Winkler, 1965, Winkler et. al. 1974, Weaver, 1976 and Ware,
1983).

Controlling house sparrow birds and improving Thompson Seedless Grapes
The present investigation aimed to throw some light on the
efficiency of certain integrated bird management applied in vineyards
on checking bird attack and improving quality of Thomson seedless
grapes.
MATERIAL AND METHODS
The present study was carried out during the two successive
seasons of 2004 and 2005 on 6-year old mature, own-rooted
Thompson seedless grape road grown in newly reclaimed area of
Nubaria farm, Cairo Alexandria desert rood. The vines were planted in
a light calcareous sandy soil and spaced at 1.5m (between vines in the
row) X 2.75m (between rows). The vines were trellis trained and cane
pruned. Five canes 14 buds each and approximately five renewably
spurs, two buds each, were retained on each vine at winter pruning in
the middle of January in both seasons according to Fawzi et. al.,
(1984). The vines were drip irrigated and fertilized with macro and
micronutrient via fertigation. All vines received the same agricultural
practices already applied in the vineyard.
Experimental vines were chosen several weeks prior to anthesis
on the basis of uniformity of foliage and cluster development. All
vines were adjusted to the same cluster number (i.e. 25 clusters) prior
to anthesis.
The experimental treatments tested in this trial were as follows:
Pesticides used:
A)
B)
C)
D)
Pyriban 48% E.C. (Chloropyrifos): 0,0 – diethyl – 0 – (3,5,6 trichloro
– 2 – Pyridyl ) phosphoro thioate.
Cidial – L 50% E.C. (Phenthoate): S – (& - ethoxy – carbonyl bonzyl)
– 0,0 – dimethyl phosphorodithioate.
Captan 50% W.P. (Captan): N – trichloro methylthio – 4 –
cyclohexene – 1,2 – dicarboximide.
Bayfidan 25% E.C. (Triadimenol): B – (4 – Chloro – phenoxy ) & (1,1 – dimethyl ethyl ) 1-H- 1,2,4 triazole – 1 – ethanol.
Physical and chemical characteristics of berries:
Clusters were harvested in both seasons when the total soluble
solids of the untreated berries reached about 16-17% according to
Tourky et. al., (1995). At harvest time (last week of July) from each
-393-

treatment, six samples each containing 50 berries were used for
physical and chemical determinations such as average berry weight
(g), diameter (mm) and size (cm)3. In addition berry dimensions (i.e.
length and width) and berry shape index were calculated. In the juice,
the chemical traits were determined i.e total soluble solids, total
acidity (as g tartaric acid / 100 g Juice) and ratio between total soluble
solids and total acidity% according to the methods outlined by
A.O.A.C. (1985).
Evaluation of the efficiency of some approaches of integrated bird
management (IBM):
Recently in Egypt, noxious bird species (i.e. house sparrow,
Passer domesticus niloticus) severely attack the different growth
stages of Thompson seedless grape fruits. To solve this problem the
efficacy of some control techniques and approaches were evaluated
against house sparrow birds. This was implemented in accordance to
the vineyards protection index (PI) research programs under different
agro ecosystems.
Mechanical approaches:
Effect of nylon fish nets:
Nylon fish net was evaluated under the conditions of Thompson
seedless grape fruits in Nubari farm at Alexandria desert road. Three
plots, each of 20m2, were covered directly by nets before ripening
stage. Other plots were left without covering as control. Damage and
undamaged sprouting were assessed after 3, 7 and 15 days. Damage
percentage was calculated using the following formula:
Average No. of damage fruits
% bird damage = ‫ ــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــ‬x 100
Average No. of total investigated fruits
The reflecting stripes:
The effectiveness of reflecting strips in repelling the noxious
birds from the field crops was evaluated under the conditions of
vineyards. Three tested field, each 2 feddans. At the experimental
area, reflecting stripes, 11 mm wide and 30 m length with different
colours were stretched and strung on 2m wooden poles against the
-394-

wind direction at 5 m intervals in parallel strands above the plants with
0.5 m. One feddan was completely covered with 10 rollers of
reflecting stripes. Another feddan was left without treatment as control
far at lest 500 – 100 m from the treated ones (Conover and Dolbeen,
1989). Bird damage was assessed in the treated and untreated areas
and protection index (PI) was calculated by the equation adopted by
Inglis and Isaacon (1987):
A–B
% Protection Index (PI) = ‫ ــــــــــــــــــــــــ‬x 100
A
Where
A = Mean damage percentage in untreated area.
B = Mean damage percentage in treated area.
Chemical approaches:
Repellency action of tested compounds :
Trial was conducted under the conditions of vineyards fields to
examine the repellency potential of Pyriban, Cidial-L, Captan and
Byfidan. Each compound was applied at 0.5 and 1.0% level once in
water on June 10, 2004 and 2005 (about 6 weeks before harvest).
Experimental plots of Thompson seedless grape were separated from
each other by about 3 meters. Three replicates were used for each
treatment. Spraying the pesticide was carried out by using a motorized
knapsack sprayer. Bird damage assessment was carried out in treated
and untreated area after 15 days from spraying (El-Deeb, 1990).
Damage percentage and protection index (PI) were calculated as
mentioned before.
All the obtained data were tabulated and subjected to proper
statistical analysis according to Snedecor and Cochran (1967) using
new L.S.D test to differentiate the different between various treatment
means.

RESULTS AND DISCUSSION
Effect of some insecticides on the physical and chemical properties
of the grapes:
Table 1 shows the effect of some insecticides on some physical
and chemical characters of Thompson seedless grapes during 2004
and 2005 seasons.
It is clear that application of the four bird repellents namely
Bayfidan, Pyriban, Captan and Cidial L at 0.5 to 1.0% significantly
improved quality parameters of the berries in terms of increasing
weight, size, dimensions of berry and total soluble solids, while
reduced total acidity compared to the control treatments. Spraying
Cidial L, Captan, Pyriban and Bayfidan, in the descending order was
very effective in promoting the quality of the berries. Increasing the
rates of each bird repellent from 0.5 to 1.0% caused a slight and
insignificant promotion on fruit quality. Significant differences on all
quality parameters among the four bird repellants were observed.
Treated berries tended to be roundish. Regarding to the quality of
Thompson seedless grapes, the best results were obtained when
attacking birds was carried out by Cidial L. The control treatment gave
unfavorable effects on fruit quality these results were true in both
seasons.
The scaring of birds by birds repellents materially was
accompanied with protecting the clusters from the incidence of
various diseases namely rots which reflected in obtaining heaviest
clusters and higher yield. The disappearance of rots from clusters was
also accompanied with decreasing fruit dropping and succeeded in
gaining heaviest clusters (Weaver, 1976).
The obtained results are in accordance with those of Winkler
(1953) and Winkler et. al (1974).
Efficiency of integrated bird management (IBM) Programmes:
The effectiveness of the different methods of bird management
was examined at Nubaria farm. The methods of bird management
should be sequenced and priority should be given to the methods
which will have the least impact on ecosystems, stability and natural
balance. The objective of integrated pest management is to alleviate
damage and not to destroy the pest species.

Mechanical approaches:
The efficacy on nylon fish nets and reflecting stripes:
The effectiveness of nylon fish nets and reflecting stripes in
protection of vineyards from the attack of sparrow species in Nubaria
farm are shown in Table 2. Result obtained indicated that the highest
values of protection index (PI) occurred by using both mechanical
programs during 2004 and 2005 seasons of Thompson seedless grape.
The PI with nylon fish nets and reflecting strips were 56.11 & 74.51%
and 63.88 & 77.94% during the two seasons, respectively.
These findings are in accordance with those of Buggers and
Ruelle, (1982) and Plesser and Omasi (1983), who reported that
physical barriers such as nets or acrylic fibers could prevent the bird
attacks to fruits or seed field and provide almost complete protection.
The nets are non-toxic, noiseless, and reusable barriers that achieve
100% effectiveness. Since nets are expensive, therefore, it can be used
only to protect high-value crops, protection schemes and nurseries at
research centers.

Data in Table 3 indicated that tested pesticides when used at 0.5
and 1.0% achieved considerable protection for Thompson seedless
grape, i.e. 53.56 & 53.62 and 87.78 & 79.80 for Pyriban; 68.10 & 67.4
and 68.74 & 86.96 for Cidial-L; 21.60 & 53.40 and 33.10 & 88.50 for
Captan; 33.69 & 85.86 and 86.53 and 91.12% for Bayfidan against
house sparrow birds in Thompson seedless grapevine field during
2004 and 2005 seasons, respectively.

Sh. M. Abd EL-All et. al.
It was observed that spraying pesticides at 1.0% gave the
highest efficiency in Thompson seedless grape protection during the
two seasons compared with 0.5%. Statistical analysis showed
significant differences between the tested compounds.
It is evident that the high repellency effect against the house
sparrow birds was occurred with pyriban and Bayfidan during 2004
seasons, while was with Captan and Bayfidan during 2005 seasons
and the lowest with captan during 2004 seasons. On the other hand, all
tested compounds exhibited different repellency effect under the
conditions of field during the two seasons. This may be due to the
pressure of bird in field crops.
It could be concluded that the effectiveness of the tested
compounds differed considerably according to the type of chemical,
concentration and density of birds. Results of Kahi and Samson
(1984); Flegler et. al. (1987) ; El-Deeb (1990) and Abd-El-All et. al.
(1995), who worked on the effect of some pesticides as a bird
repellent and protection of crops against sprout damage by house
sparrow birds could support the present results.
As a conclusion, it is recommended to use reflecting stripes as
bird scaring for alleviating the great damage caused by birds and save
the ecosystem stability in Thompson seedless grapevine vineyards.
