Neem on major pests

 

 
Desert Locust
Neem oil causes solitarization of gregarious nymphs @ 2.5 lit/ha. They became solitary, lethargic, almost motionless and highly susceptible to predators like birds 
 
 
Army Worm
Retard growth, repel adult, Inhibit feeding, disrupt molting, toxic to larvae
  
Cockroach
Neem seed extract kills young cockroaches and inhibits adults from laying eggs  
Mealy Bugs
 
Repels, Inhibit feeding
 
Green Leaf Hoppers
Inhibits feeding Brown
Rice, Cowpea and
Boll Weevils
Inhibits feeding, disrupt growth, toxic
 




Plant Hoppers
Reduction in survival, affect the development of nymphs to adults stage, oviposition deterrent, sterility, repellent, mating failure

Fire ant
Inhibit feeding
 
Mosquito
Throwing crushed neem seed into ponds prevent breeding and affect larvae
Cabbage loopers Inhibit feeding, disrupt growth
 
Mexican Bean Beetle
Retards growth, inhibit feeding, disrupt molting  
Rice gall midge
Toxic
 
Khapra Beetle
Inhibits feeding, disrupt molting, toxic to larvae Bean  
Gypsy Moth
Retards growth, Inhibit feeding, disrupt molting
 
Aphid
Reduces fecundity, disrupt molting  
Leaf Minor Larvae
Unable to molt, retard growth,Inhibit feeding
Diamond Back Moth Strongly suppresses larvae and pupae, retard growth, Inhibit feeding  
Fruit flies
Repellent, (100 % control by neem spay under tree) Inhibit nematode hatching, prevent second stage juvenile (by use of neem cake incorporation in soil)

Pink Boll Worm
Retards growth, Inhibit feeding
White fly
Repellent, growth retardent, feeding inhibitor
 
Sorghum shoot fly
Feeding inhibitor
 
Spotted cucumber beetle
Growth retardent, feeding inhibitor
 
Snails
Kills snails
