Mango Pests
 
  • Hoppers (Idocerus atkinsoni)
  • Mealy bugs (Drosicha mangiferae)
  • Fruit fly (Bactocera dorsalis, B. zonatus)
  • Scales (Aspidiotus distructor, Parlotoria pergandei)
Mango Hopper
Two spp. (Amritodus atkinsoni & Idioscopus clypealis) -- Cause 60% losses
Adult (Idioscopus clypealis)
Large ( 6.3 mm)
Greyish in colour
(Amritodus atkinsoni )
Smaller ( 5.1 mm)
Greyish in colour
Nymphs Dull Green Less active Pale Yellow, more active
  • Prefer humid climate and therefore more attack on thick Canopy plants.
  • Active during Spring and Monsoon season I.e. Feb - April & June –August.
  • Spend Winter (dormant period) sitting around the main trunk.
  • Suck sap from Inflorescence and tender shoots
  • Excrete honey-dew
  • Nymphs dull green, voracious feeders
  • Very active from March – August
  • Over-winter under tree bark
  • Adults grayish, about 5 mm long
  • 200 eggs/female, singly embedded in plant tissue
  • Inflorescence withers and turn brown
  • Fruit drops pre-maturely
  • Prefer humid climate
Mode Of Damage
  • Cause damage by sucking cell sap & by egg laying in the inflorescence and young leaves by injecting ovipositor.
  • Inflorescence wither up & turn brown
  • Excrete honey dews which serve as media for sooty mould development
  • Both Nymphs and Adult damage the plant, but nymphs are more harmful due to voracious feeding.
 
 
Control Measure
CULTURAL
  • Proper Pruning to allow sun light inside plant canopy
  • Remove bunched leaves & malformed panicles
CHEMCIAL
  • Spraying with Confidor 200 SL @ 30-50 ml / 100 lit. of water
  • use mist blower
  • Avoid run-off the spray mixture.
  • Volume of water according to plant size
  • Spray inside canopy including main stem and branches
Mango Mealy Bug
  • Active from December to May and spends diapause in egg stage in the soil up to 6 inch depth ( June - Nov )
  • Male--winged while female--wingless, flattened body with white powder.
  • Nymphs ( 70 -80%) crawl on plants during January - March
  • Complete their development by April & mate
  • Deposit eggs in April-May in soil in a silken purse
Mode Of Damage
  • Cause damage by sucking cell sap from twigs, leaves & inflorescence
  • The young fruits shrivels become juiceless & drop off
  • Nymphs & females are harmful, whereas male do not feed only mate,
 
 
Control Measure
  • Destroy eggs under soil of infested tree by scraping the upper 6“ of soil or by drenching 2 % Hostathion Solution in soil
  • Use sticky bands in end December
  • Slippery bands ( Polythene )
  • Trap band ( Cotton layer & Gunny bags)
  • Sticky band ( Molesis, Greece, Cooltar
  • Readymade available Ostico & Namhar)
  • Spraying with Confidor SL 200 @ 50 ml / 100 lit Of Water.
Mango Scales
  • About 27 species of scales attack on mango
  • Usually dispersed by birds & bats through their feather & fur
  • Active during November ---- January
  • Male is smaller than female ( Oval in shape having transparent skin coat )
  • Secrete wax which give it protective cover on both sides
  • Upper side ---- hard while Lower side ----- Soft
Mode Of Damage
  • Cause damage by sucking cell sap from soft twigs & leaves
  • Yellow spots on attacked leaves & ultimately drying of whole leaves
  • Nymphs & Young females are more harmful
Control Measure
  • Remove & burn infested leaves & twigs
  • Spraying with Confidor SL @ 50 ml / 100 lit. of water.
Mango Fruit Fly
  • Three spp. ( Dacus zonatus, Dacus dorsalis, Dacus ferrugeneus )
  • Active during Summer months & diapause in pupal stage in winter.
  • Active at 25-30 C & become inactive below 20 C
  • Adult is stout & little bigger than housefly
  • Lay eggs in clusters in fruit skin with its sharp ovipositor at the start of ripening.
  • Legless larvae (Maggot) with pointed anterior & yellow in colour
  • Grubs feed on pulp
  • Grown grubs are yellow-opaque measure 8 mm
  • Active in summer, over-winter as pupa in soil
  • Very active from February – May
  • Adults are brown with transparent wings
  • Female lays 50-200 eggs, in clusters of 2-15
Mode Of Damage
  • Maggots feed on pulp of fruit & secrete excreta which is deposited in the fruit
  • No visible scar traceable on fruit in the early stages of attack
  • Brown spots appear on the surface of infested fruits in later stages
Control Measure
  • Destroy & burn all infested fruits to reduce future pest attack
  • Apply traps of methyl eugenol (3-4 trap/acre--Replace lure after every 14 days)
  • Spray with Dipterex 80 SP @ 100-150 gm / 100 lit Of Water
