282 PROCEEDINGS OF THE SECOND ENTOMOLOGICAL MEETING 
Leaf-eating insects on cauliflower include :— 
Pieris brassice. 
Plutella maculipenms. 
Plusia signata. 
., orichalcea. 
Crocidolomia binotalis. 
Hellula undalis. 
Agrotis ypsilon. 
Athalia proxima. 
Monolepta signata. 
Phyllotreta chotanica. 
All of these were included under cabbage and there is little to add here 
except that the larva of Hellula undalis bores the stem of cauliflower 
and that Phyllotreta chotanica occurred in large numbers at Pusa in. 
March 1916. 
In addition to the foregoing leaf-eaters, we have :— 
Plusia ni. 
Plusia ni has been bred at Pusa and Lahore on cauliflower and at 
Surat and Kumbhariya (Surat) on cabbage, but it is scarcely a pest. 
Phyllotreta vittata also occurs on cauliflower in the Katha District, 
Burma. 
The flowers of cauliflower are attacked by Aphids; but these are 
scarcely pests as a rule ; and the seed-pods are attacked by Bagrada picta 
in the same way as cabbage. 
Kwot-Kontu (Brassica oleracea caula-rapa). 
| Kohl-rabi. | 
The only important pest found on knol-kohlis Hellula undalis which 
was considered under mustard. 
Hellula undalis feeds on the leaves, webbing them up, and also bores: 
inthe root. In the coloured plate, a knol-khol is shown in figure 6, which 
shows how the eggs are laid, and how the caterpillars web up the leaves 
and bore in the tuberous root, the entrances of their tunnels being marked 
by the masses of extruded frass. Prompt destruction of the first lot 
of larvee is the only control-method. 
Turnip (Brassica sp.). 
Turnip leaves are attacked by :— 
Athalia proxima. 
Crocidolomia binotalis. 
Flea Beetles.
