Aphids are soft bodied insects and 1.5 to 2 mm in length.
Adults are large sized, black with pear-shaped body and
conspicuous cornicles, winged or wingless.
Nymphs are reddish brown.
Both nymphs and adults when on stem are found with their
head directed towards the soil.
It is a serious pest of safflower.
During pre-flowering stage both nymphs and adults suck the
cell sap from shoot apices,
peduncles, leaves and stem, secrete a honey dew like secretion
on upper surface of the leaves and plant parts forming a black
sooty mold which hinders photosynthetic activity resulting
in stunted growth.
Finally the plants dry up.
Honey dew excreted gets deposited on the upper surface of
the leaves, on which sooty molds grow and hinder the
photosynthesis, resulting in stunted growth and poor yields.
In case of heavy infestation the plants dry and die.
Infestation may start even when the crop is 15 days old.
About 40-50% yield losses are observed due to this insect.
Infestation may occur 30-45 days old crop.
Avoid late sowing.
If the attack is observed
in the border rows take control measures.
Avoid excess use of
Use resistant varieties.
Maintain 2 or 3 rows of
Maize and Sorghum around the fields.
Release Coccinellids, chrysopids, praying mantis, Syrphids ,
Release of Chrysoperia eggs/grubs @ 1-2/plant.
Release endoparasite, Pseudendaphis sp., in the first week
