Mealybug insects are oval in shape and have a life cycle of four stages in female —. Egg, larva I, larva II and adult. Initially the affected portion will be chlorotic, later changing to brown colour and dry.
Black colour
The insect excretes honey dew, and as a result the infested portion becomes shiny and moist and to this, secondary infection by sooty mould fungus, capnodium occurs resulting in black colour covering the affected parts.
Yellowing of leaves, malformation of affected portion due to toxin injection, stunted leaf growth and fruit tip, presence of red/black ants, honey dew excretion, are some of the symptoms to watch for.Reproduction
Normally oviparous, eggs are laid just beneath the body or just at the posterior end of the abdomen. Each female is capable of laying about 400 to 500 eggs. Nymphs become adults in a month. Adult lives for about 30-60 days depending upon the environment and may move from one area to another till it finds a suitable place for feeding and reproduction. Normally they are seen beneath the stem, under surface of the leaves, in the leaf axils, flower buds and fruits and occasionally on the roots.The insect is polyphagous. In addition they also attack a variety of weeds, which serve as alternate hosts when main crop is not available.
Management
— Remove alternate weed hosts and destroy the infested parts of the plant,
— Take up the management at initial stage to get maximum control
— Wherever necessary, use botanical insecticides like neem derivatives such as azadirachtin 0.03 percent neem oil 2 percent NSKE 5 percent and fish oil rosin soap at 25g/litre of water.
— As a last resort use any recommended chemicals at the right dose for maximum control.

Citrus Mealybugs (Planococcus
Citrus Mealybugs (Planococcus citri) females are small (less than 1/8 of an inch long), mealybugs with a faint gray stripe running down their back. They also have short waxy filaments around the margin of their oval body with a slightly longer pair of filaments at their rear. Females produce a cotton-like egg sac containing yellow eggs and lay from 300 to 600 eggs. Eggs hatch into small, active crawlers. When the crawlers settle down to feed, they begin to secrete wax and produce honeydew. Males resemble females from the egg stage to the 3rd instar nymphal stage. After pupating, the winged adult male emerges but only lives for 1 or 2 days and does not feed.

Thanks for sharing the information which is efformative. The phenomenon to use botanical insecticides like neem derivatives such as azadirachtin 0.03 per cent neem oil 2 percent NSKE 5 percent and fish oil rosin soap at 25g/liter of water. — As a last resort use any recommended chemicals at the right dose for maximum control. After fortnight check for newly emerging crawlers; if necessary, go for second spray. Thanks. Regards

The information about the Mealybug insects regarding their shape, life cycle, colour and reproduction is very interesting. Want to know some of the symptoms. Thanks. Regards,

It is a great insect to watch it life cycle. It is not long and it is worth watching it. Each stage is specified by a mark, i found some documentary mp3 file about it here. By the way i would like to know the color of the insects at the adult stage please.

This is broad leaves crop and very sensitive to chemicals. So, the use of Weedicide should be very carefully. It can be done in the following manner- (i) Pre-plant soil incorporation: Use EPTC @ 1-2 kg ha-1 or Fluchloralin @ 1.0 kg ha-1. EPTC is known to increase the proportion of large sized tubers in the harvest, quite apart from its weed control effect.
Reproduction
Each female is capable of laying about 400 to 500 eggs.Per day or other units.
Mealy bug lays eggs in which place.
Reproduction
Female laying@400-500 eggs durin their life time(30-45 days)
Mealybug lays eggs beneath the leaves, flowers, nodes and sometimes in soil.
Management
Mechanical Management
Management
Mechanical method:
Insecticides:
Add diamethoate 30% 265ml or phosphomidon 85%. or 1kg soap powder and any of the above insecticide mixed in 500 liters of water.
management
1. use of grease band on the trees to prevent its entry
2. remove the host plants from the field or spray insecticide in early stages on the host plants also
3. organic method - neem extract 1500 ppm + gomutra spray + apsa-80 ( twice /thrice )
