A note on Pyrilla perpusilla Walker on maize



A note on Pyrilla perpusilla Walker on maize



Indian Journal of Plant Protection 18(1): 113-114



During outbreaks of the maize pest Pyrilla perpusilla in Uttar Pradesh, India, in 1985 and 1987, its preference for different cultivars was studied. Of the 13 cultivars tested, J 115, Kanchan and Ganga 2 were the least preferred for oviposition. Adults and nymphs were parasitized by Epiricania melanoleuca, and eggs by Tetrastichus pyrillae. In 1985, the maximum pest population (12.1 adults/plant) was recorded in the 2nd half of August, falling to 1.8 adults/plant in the 2nd week of September.
