SAFETY OF ENDOSULFAN AND DICHLORVOS TO FOUR PARASITOIDS OF LAC INSECT PREDATORS
Indian lac insect, Kerria Iacca (Kern) is a minor pest on some horticultural plant species such as Zizyphus Mauritiana Larnk. (ber), Annona squamosa Linn. (custard apple), Ficus carica Linn. (anjeer) (Roonwal, I962) and Wris vinifera Linn. (grape) (Mehra, I955). The insect also thrives on a number of forest plants. It is being cultured on a number of plant species of minor economic importance for the production of shellac, lac wax and lac dye. These being non-toxic natural products, have tremendous export potential. A number of insectsvare closely associated with lac insects, of which three are major predators viz.; Eublemma amabilir Moore (Lepidoptera : Noctuidae), Pseudahypatopa pulvera Merk. (Lepidoptera : Blastobasidae), Chrysapa sp. (Neuroptera: Chrysopidae). There are also eight parasitoids of minor importance.
