19. Vespula germanica attacking A. mellifera hive

20. Vespula vulgaris attacking A. mellifera worker

21. Extent of damage
• Vespa velutina may kill 718 bees in 4 hours duration during the peak
attack
• Vespa mandarinia may cause a strong colony to an unproductive stage
in 3 hours
• A loss of 20-25 % of bee colonies in the apiaries has been estimated
• Apiaries near the foot hills >in hills

22. Management options for reducing the damage to honeybee colonies
• Most bees and wasps are highly beneficial as predators of
pest insects or as pollinators
• Locate nests of wasps and destroy them
• Bait /trap the wasps in the apiaries. Various traps have
been designed for wasps
– Killing the wasps with broom attracted on sugar or gur
bags sprayed with water
• Killing of queens coming out of hibernation during spring
has also been suggested
• Eliminating alighting board and reducing hive entrance
• Flapping the visitor wasps at the hive entrance or
foraging in and around the apiary
• Use of screen and bee wasp protectors

31. • Ants are not usually serious pests
• Occasionally, may enter colonies in search
of food or establishing nesting sites
• Ants are typically found between the
inner and outer covers of the hive and in
pollen traps
• Persistent attacks by ants sometimes may
induce absconding in honey bee colonies
• Even though majority of the ants’ species
seldom disturb the bees, but can be a
nuisance to the beekeeper
• May take way feed, larvae and dead
adults
• Invade hives frequently in monsoon
season and lay eggs as well

37. • Use propolis to fill cracks and crevices
• Maintain strong colonies
• Keep bottom boards raised off the ground
• Place the colony on stand with oil or sticky barrier
• Create a slippery barrier by using AntCant and Tree Tanglefoot
• Alternatively, put legs of the stand in broad earthen bowls full of water (ant wells) to
check entry of ants into the hive
• Use carbon disulphide fumigation (2-4 tsp.) or 0.2% chlorpyriphos to destroy
underground nests of ants
• Colonies capable of defending by fanning should be selected and used as breeder
colonies for mass rearing of queen bees
• Brush away if few ants are invading the colony
• Repellents e.g. sulphur powder, borax powder, sodium fluoride can be used against ants
• Spread diatomaceous earth or cinnamon around your hives

39. • Major pest in USA, Australia, Europe and Africa
• Adults are oblong in shape
• Around 5-7 mm long
• Body coloration: tan to reddish-brown, dark brown
or black
• Head and antennae tucked down beneath the thorax
• A single female beetle can produce over 1000 eggs in
her lifetime, in clusters of 10–30 eggs
• Eggs are similar in shape to those of honey bees, but
2/3 the size
• Larvae are elongated, cream-colored to slightly
golden grubs (10-12 mm)
• Larvae prey upon A. mellifera honey, pollen, and
even brood
• Severe infestation makes honey slimy and defecated
and colony may abscond

43. • Common pest in sub- Saharan Africa
• Adults are broader and oblong in shape
• Around 20-23 mm long
• Body coloration: black with orange antennal tips
• Eggs are oval white (2 to 3 mm)
• Mature larvae are white with orange heads and pearly
abdomen (10-12 mm)
• Larvae preferentially feed on young honey bee larvae
• Larvae prey upon A. mellifera honey, pollen, and even
brood
• Heavily infested honey bee colonies can have 700 or more
adult beetles
• Severe infestation makes honey slimy and defecated and
colony may abscond

46. Management
• Maintain strong colonies
• Control mites and other stresses
• Remove burr comb
• Keep the apiary clean
• Eliminating eggs or hatchling sources such as cow dung & leaf litter
• Seal cracks & crevices
• Clean bottom board
• Remove extra honey and pollen frames
• Place diatomaceous earth, and/or slaked lime around the hives
• Diatomaceous earth tested in traps killed 100% of beetles tested
through dehydration (Cribb et al., 2013)
• Honey supers can be frozen at -12°C for 24 hours to kill all stages of
beetles
• Bacillus thuringiensis and EPNs like Steinernema riobrave and
Heterorhabditis indica
• Use of beetle traps

47. Beetle traps
1. West Beetle Trap
2. Freeman Trap
3. Bucket traps
4. Bottom bar box traps
5. Baited flight traps
6. Pitfall traps: Beetle Barn plastic trap, Beetle Blaster, AJ’s Beetle
Eater, and Beetle Jail Jr. Traps
7. Fabric entanglement traps: Beetle Bee-Gone

48. West Beetle Trap
• The West Beetle Trap is placed on the
bottom board, and requires a wooden
shim to maintain proper space beneath
the frames
• It contains a shallow pool of oil, and is
covered by a slatted screen that excludes
bees
• Adult beetles enter the trap from above,
to escape from bees, and fall into the oil
and drown
• Hives must be kept extremely level for
these traps to be effective
• These traps preclude the use of screen
bottom boards for ventilation.

49. Freeman beetle Trap
• The Freeman Beetle Trap is similar to
the West Trap in function
• It replaces the bottom board with a 3 mm
(1/8”) screen mesh, as used for varroa
control
• An oil-filled tray is inserted into a
compartment below the screen
• Adult beetles enter the trap to escape
from bees, and fall into the oil and drown
• Wandering beetle larvae may also fall into
the trap as they attempt to exit the hive to
pupate
• These traps can passively eliminate some
varroa mites as well
• Hives must be kept level for these traps
to work.

50. Beetle Barn Plastic Trap
Placed on top of frames, with
small entrances that only
allow beetle entry
Beetle bait recipe:
•1 cup of water
•1/2 cup of apple cider vinegar
•1/4 cup of sugar
• Peel of 1 ripe banana- chopped
into small pieces

foragers on an average is 708 ± 111.2 foragers/ day are eaten per
bird
 Predation was normally maximum between 1000 to 1300 h
whereas it was minimum between 1600-1900 hr.

63. Management
