RECENT STUDIES ON THE MANAGEMENT OF MANGO STONE WEEVIL STERNOCHETUS MANGIFERAE FAB. (COLEOPTERA : CURCULIONIDAE) IN SOUTH INDIA
Mango stone weevil, Sternochetus mangiferae Fab. an important insect pest of mango fruit is amenable to control in the early stage of fruit-set. In South India, the varieties Banganpalli, Totapuri, Alphonso, Neelum etc. are highly susceptible. The objective of this study therefore, was to develop a timely management schedule leading to pest-free fruits at harvest, which is a prerequisite for export and processing. Field studies were carried out to evaluate insecticidal treatments of IIHR and in farmers' fields, the latter with the help to Agricultural and Processed Food Products Export Development Authority (APEDA). Results showed that intervention with a single spray of monocrotophos 0.05% or Fenthion 0.08% at pea to marble size (middle of March) showed 13 to 15% infestation as compared to 34% in control in 1997. Two sprays of monocrotophos 0.05% at a 10 day interval, in 1998, and destruction of fallen fruits (at and just before harvest of previous year) resulted in 97.5% and 100% control in Banganpalli and Alphonso. In the farmers field in Andhra Pradesh, South India, two experiments with three sprays of monocrotophos 0.05% or fenthion 0.08% at pre-flowering, at pea size and at marble size gave 100% control, thus ensuring pest-free fruits for export and processing.
