Abstract

Aleurolobus barodensis (Maskell) was more abundant than Neomaskellia andropogonis Corbett on sugar-cane in Pakistan. Azotus delhiensis Lal, Eretmocerus sp., Prospaltella flava Shafee, Amitus sp. and Tetrastichus sp. parasitized nymphs and pupae of A. barodensis and E. serius Silvestri those of N. andropogonis. Chrysopa carnea Steph., Brumoides suturalis (F.), Catana parcesetosa (Sic.), Oenopia sauzeti Muls., Scymnus sp. and S. nubilus Muls. preyed on the immatures of the aleurodids.

In Peshawar valley where the crop is aerially sprayed twice a year to control Chilo infuscatellus Sn., Tryporyza nivella F., A. barodensis and Pyrilla spp., the rate of parasitism on A. barodensis was very low and its density was very high, being 330 immatures/leaf at Charsadda and 425 at Mardan in November 1979. At Sialkot (Punjab) where the crop is not sprayed, the rate of parasitism, mainly by A. delhiensis and Amitus sp., at this time was 22% and the density of A. barodensis was 70.4 immatures/leaf. The maximum rate of parasitism was 71% in January. The abundance of A. barodensis in Peshawar valley seems to be due to the mortality of natural enemies because of aerial spraying, therefore, judicious use of insecticides and redistribution of natural enemies in these areas is recommended.
