Experiment Background
India is the world’s largest mango producer, accounting for 54.2% of global production (Fivaz, 2009). Mango is attacked by more than 400 pests in the world (Tandon and Verghese, 1985). Several fruit borer species of mango is identified so far in different mango orchards in India. The mango fruit borer, Citripestis eutraphera (Meyrick), (Lepidoptera:Pyralidae) originally confined to the Andaman Islands, is a recent invasion in mainland India. C. eutraphera which was originally described from Java, is a significant borer of mango fruits in South and South-East Asia and some parts of Australia (Anderson and Tran-Nguyen, 2012). The most recent classical example of intra-national invasion of insect pests from the Andaman and Nicobar Islands to mainland India is the mango fruit borer, C. eutraphera (Jayanthi et al., 2014). They first time reported the occurrence of C. eutraphera causing extensive damage to immature fruits of mango in Karnataka and Tamil Nadu. Recently, infestation of C. eutraphera was reported first time causing extensive damage in Gujarat (Bana et al., 2018). Mango-growing pockets in the southwestern parts of Gujarat, as well as parts of Kerala and Tamil Nadu were moderately to highly suitable for C. eutraphera distribution in 2050 and 2070 (Choudhary et al., 2019).
Mango fruit borer has become a serious problem in major mango growing areas of Gujarat and peak infestation of this pest occurs during April-May, which approximately coincides with ‘marble stage’ of fruit development. The damage is done by the larvae feeding on fruits by weaving web connecting adjacent fruits. The young larvae scrap the epidermal tissue and the mature ones bore into the fruit and feed on the pulp. The affected fruits exude resin and black or brown rough sticky patches can be seen on the infested area. The entry portion starts decaying due to secondary infection, which subsequently spread to the pulp rendering them unfit for consumption. By considering the economic importance of C. eutraphera the present study will be carried out.
