Management of Citrus Pest
New Flush of Plant Temperature
New flush is necessary to
female to lay eggs.
At 68-86 ⁰F, Females lives
about 30-35 days and produce
300-800 eggs (Citrus psylla).
It is also necessary for the
subsequent development of
nymph.
When temperature is above 90
⁰F, then female lives about less
than 30 days and produce
about 70 eggs ( Citrus psylla).

3. 
IPM strategies are used to maintain the population
of Citrus pest effectively like Cultural, chemical
and biological control.
Young trees are at great risk than mature trees
because of the attraction of adult psyllid.
It is necessary to protect the young plants around
4 years.

Soil-Applied Systematic
Insecticides
Broad Spectrum Foliar
Insecticides
Long lasting control of
psyllid about 8 weeks.
Short lasting control of
psyllid about 4 weeks.
Least impact of beneficial
insects.
Residual affects of
insecticides.
Application should be
early as 30 days before
initiation of flush.
Applied on early season
flush period when
temperature is below 90⁰F
and psyllid is abundant.

5. 
Biological Control
Female lays about 800 eggs and 90% of hatching eggs
in the field not reached to become adult (Citrus
psylla).
It is due to control done by natural enemies
Predator
Ladybeetles
Parasitoids
Tamarixia radiata (Parasitic Wasp)
