2. INTRODUCTION Honeybees play a vital role in the pollination
of agricultural crops In recent years honey bee colony declines
have reached 10-30% in Europe, 30% in the United States and up to
85% in Middle East, but such declines are not apparent in South
America, Africa and Australia (Kluser,2010) The syndrome behind
honeybee population decline is known generally as Colony Collapse
Disorder (CCD), which is characterized by a rapid loss of adult
worker bees (van (Engelsdorp, 2009) EMFs are mentioned as a cause
of honeybee colony losses, the sudden disappearance of honeybees,
which is a huge problem in the field of beekeeping (VanEngelsdorp
et al,2009)
3. There are several factors for CCD and they fall into two
main classes: living organisms human activity Electromagnetic
radiation can best be described as waves of electric and magnetic
energy moving together (i.e. radiating ) through space .
Electromagnetic fields (EMF) are physical fields that are produced
by a source of EMR. Electric fields are associated with electric
charge and magnetic fields with the movement of electric
charge.

within 50 to 300 meter radius are in the high radiation zone (dark

radiation

6. MATERIALS AND METHODS Fifteen boxes of bees were place at
specified locations. First three boxes were placed below the mobile
tower. After measuring 200m, 400m, 600m and 800m distance from the
tower, three boxes were placed at each location, respectively. At
each place 3 replications was taken. 6 Treatment was considered at
every place. Assuming first treatment as a no. of bees
(bees-strength), second, third, fourth, fifth and sixth as area of
honey, egg, larva ,brood and pollen. Each were be measure after 14
days interval. The experiment was divided into 5 spot with each
spot different distances: Spot 1: 0 m Spot 2: 200 m Spot 3: 400 m
Spot 4: 600 m Spot 5: 800 m

2012
31. RESULTS AND DISCUSSION Bees-strength in the starting of
experiment in T1 (0 m, beneath, the mobile tower) was found to be
19,832.33 while, it was seen increased 26,053.33 at the end of
experiment, the first week of October, under the influence of
electromagnetic radiations emitted from the mobile tower. The
overall progressive increased in honey area recorded during the
month of June-October, Area of comb, filled with honey was
increased 340.833 cm2 in T1 (0m, beneath, the mobile tower) while,
decreased in -297.5 cm2 in T5 (800m) followed by T4 (600 m) in
266.2 cm2 , -264.734 cm2 in T3(400m) and -92.5cm2 in T2(200m).
32. On the basis of observations recorded, it was revealed that
the area of egg was significantly increased in T3 (T1102.5 cm2 )
and T1 (23.334 cm2 ) whereas, it was found to be decreased in T2
(-34.167 cm2 ), T5 (-13.836 cm2 ) and T4 (- 6.667 cm2 ). The
radiation was recorded during month of June- October. Highest
radiation was observed in T1 (E =304.297 mV/m, B =541.22 A/m and S
=302.913 m W/m2 ) while minimum in T5 (E =7.088 mV/m, B =19.12 A/m
and S =0.132 m W/m2 ) followed by T4 (E =7.198 mV/m, B =19.338 A/m
and S =0.0981 m W/m2 ), T2 (E=10.663 mV/m, B= 24.08 A/m and S
=0.248 m W/m2 ) and T3 (E =20.826 mV/m, B =109.54 A/m and S=2.235 m
W/m2 ), respectively.
33. Conclusion As per the present investigation, all treated
colonies with mobile tower radiation had perform well as normal
colony and none of these colonies were perished during the
experiment. At 0 m (beneath,the mobile tower) area of honey, brood,
larva, egg, pollen all were increased. The present investigation
would help to bee- keepers of Tarai region of Uttrakhand where,
their bee hives were placed near the mobile tower .No impact of
electromagnetic radiations of colony strength and bees
survivorship.
