Aphids are small, soft-bodied
insects with long, slender mouth parts that they use to pierce stems, leaves,
and other tender plant parts and suck out plant fluids.
Low to moderate numbers of leaf-feeding aphids are usually not
damaging in gardens or on trees. However, large populations cause curling,
yellowing, and distortion of leaves and stunting of shoots. They can also
produce large quantities of a sticky exudates known as honeydew, which often
turns black with the growth of a sooty mold fungus.
Biological control: or
natural enemies can be very important in the control of aphids.
Insecticidal soap, neem oil, and narrow-range oil (e.g., supreme or superior
parafinic-type oil) provide temporary control if applied to thoroughly cover
infested foliage.and use Examples of Insecticides (Acephate – Cyfluthrin –
