Abstract
Deltocephalus vulgaris Dash & Viraktamath has recently been established as a vector of sugarcane grassy shoot phytoplasma. Germinating (single bud settlings of CoS 95255) under glass house were transplanted in 12” size pots. These were covered with cages of fibreglass sheet. The leafhoppers were released in cages. The increase in population was to the tune of 3–5 times on young settlings of 1–2 weeks, but was lower (0.5 times) on 60 days plants. The young and fast growing tender sprouts with small succulent leaves were better for sucking the juice by leafhopper and also provided nutritionally better feeding material. The mortality of nymphs was lower in 7 days young plants (26%) than 60 days old plants (90%). The transmission trials of sugarcane grassy shoot disease byD. vulgaris Dash & Viraktamath were successful on young tender plants.
