Papaya ( Carica papaya L.) is grown over 2300 ha in Maharashtra and almost 50% of the crop is utilized for papain production. Recently, the papaya crop was found to be infested by the invasive papaya mealybug (PMB), Paracoccus marginatus Williams and Granara de Willink. The PMB was first noticed in Maharashtra in the papaya orchard at Regional Fruit Research Station (RFRS), Ganeshkhind, Pune on 14 th July, 2010 by a survey team of scientists of the All India Co-ordinated Research Programme on Biological Control of Crop Pests and Weeds, Mahatma Phule Krishi Vidyapeeth, College of Agriculture, Pune.- Evaluation of Indigenous Fungal Isolates, Metarhizium anisopliae M34412, Beauveria bassiana B3301 and Nonluraea rileyi N812 for the Control of Helicoverpa armigera (Hubner) in Pigeonpea Field

The effectiveness of oil-based conidia formulations of indigenous fungal isolates Metarhizillm anisopliae M34412, Beallveria bassiana 83301 and Nomuraea rileyi N812 were evaluated against Helicoverpa armigera (Hubner) infestation on pigeon pea under field conditions. The M. allisopliae M34412 conidia in the oil formulation (7:3, diesel: Sunflower oil) were found to be most effective in controlling H. armigera. The results were compared with other control agents such as, endosulfan and HaNPV (H. armigera Nuclear Polyhedrosis Virus). The per cent efficacies were, .W. anisopliae,/i> 66.74, endosulfan 62.58, N. rileyi 60.88 and HaNPV 55.58. B. bassiana preparation was found to be relatively less effective (51.25% efficacy). The effectiveness of all the control agents based on per cent pod damage and yield has also been discussed.Keywords

Fruit piercing moths, Eudocima sp. (Noctuidae) are common pests of ripening fruit in tropical and subtropical Southeast Asia, Australia, and the western Pacific islands. Surveys were conducted in Maharashtra revealed that three abundant larval parasitoids viz., a tachinid fly, Gonipthalmus hali, eulophid wasps, Euplectrus maternus and Tetrastichus sp. were contributing up to 36.65, 41.46 and 36.58 % larval mortality, respectively. The host specificity of parasitoids was studied in the laboratory by exposing them to larvae of Eudocima sp. However, Goniopthalmus hali showed parasitization on other species of Eudocima, whereas E. maternus is found to be host specific on E. materna species. In laboratory investigation, 72 to 89% parasitization of Trichogramma chilonis on the eggs of E. materna was also recorded.
