4. _ Lady bird beetle_ Scientific name: Coccinella magnifica Kingdom: Animalia Phylum: Arthropods Class: Insecta Order: Coleoptera Sub order: Polyphaga Superfamily: Cucujoidea Family: Coccinllidae

5. Types of lady bird beetle Two spotted LBB: Adalia bipunctata Twice stabbed LBB: Chilocurus stigma Seven spotted LBB: Coccinella septempunctata Pink spot LBB: Coleomegilla muculata Mealy bug destroyer: Cryptolaemus montrouzieri Multicolored LBB: Harmonia axyridis Convergent LBB: Hippodamia convergens Spider mid destroyer LBB: Stethorus spp

6. Economic important of LBB Ladybugs are a beneficial bugs which helps rid an yougs area of crop-damaging aphids, mealy bugs and other destructive insects pests. The adults ladybugs feed on theses insects. They also lay their eggs among the aphids or other prey so the emerging larvae can feed on the insects, too. Most ladybugs voraciously consume plant-eating insects, such as aphids, and in doing so they help to protect crop. Ladybugs lay hundreds of eggs in the colonies of aphids and other plant-eating pests. When they hatch, the LBB larvae immediately begin to feed.

7. Ladybugs are considered a beneficial insects to man because they eat many bugs that are known to eat plants and destroy crops. The blood of ladybugs is yellow and has a very strong smell that act as a repllent to pedators . Beetles are value to humans in many way. They are prominent decomposers, especially in forests. As predators, they reduce populations of problem insects, especially caterpillars. LBB is widely known to be important predators of aphids, and can be purchased commercially for his purpose.

8. Most species of LBB are considered beneficial bacause they are predators of Homoptera or Acarina , many of which are considered to be pests. One type of biological control is thus called manipulative biological control (of which a subset is conservation biological control). A second type of biological control is augmentative biological control . A third type of biological control is classical or inoculative biological control.

9. The only time they are considered to be "pests" to people is in the fall when the weather gets cooler, anc the Asian lady beetles enter homes and other buildings in large numbers in search of a warm place to overwinter. Vacuuming these beetles and discarding the bag may be the most effective method of removing these insects from your home. Remember, we don't want to remove them from fields, orchards or gardens since they are so beneficial.

10. Mass production methodology of LBB Introduction: Different types of pests are found in nature affecting life and yield of nature and cultivated crops of Agro -forestry. They hamper and destroy standing and stored food reserves in every part of world. In many studies it is known that Coccinella septempunctata commonly called LBB is a capable predators and can be used for the biological control of T tabaci & T vaporariorum in greenhouse. The insects predator may commit to reproduction to varying degree depending of the nature of the prey the consume. To be successful the CSL searching strategy pre-supposes a high capacity to meet variation, plus a capacity for learning.

12. Methods 1. Adults and CSL were collected from the agriculture fields. and reared in Entomology laboratory. 2. The fields collected materials was sorted out in the lab and pairs were selected for oviposition. 3. The selected pairs were kept in separate petridishes to get the laboratory batches of eggs for single cohort off springs to minimize the variation in the experiment. 4. Then beetles were reared on aphids. The experiment was carried out in the laboratory under homogeneous condition. 5. The experiments was laid out according to complete Randomized CRD with there replication and eight treatment, the treatment means were analyzed using of variance.

13. Natural diet: Brevicoryne brassicae . 1st & 2nd instars of Macrosiphon roseae . Alete of Macrosiphon roseae . Rhopalosiphum maidis . Rhopalosiphum maidis on filter paper surface. Artificial diet: Honey syrup - was given with the help of cotton boll every day to observe longevity & data was recorded daily. Sugar syrup - daily sugar syrup was given in cotton boll the longevity on sugar syrup & data was recorded. Most swed Plain water- The boiling water in cotton boll was also given to observe the longevity & data was recorded daily
