[Great Abundance of Hvpogymna morio, L.,in Moravia.] — Ochrana 

 Rostlin, Prague, ii, no. 2, May 1922, pp. 17-18. 



An unusual infestation by Hypogymna morio, L., is recorded from 

 Moravia, about 500 larvae being found to every square yard. This 

 exceptional abundance is thought to be due to an invasion of this 

 moth from Hungary \cf. R.A.E., A, ix, 448]. Although couch-grass 

 appears to be the preferred food-plant, many other plants were also 

 attacked. The remedial measures include rolling.

Owing to weather conditions there has been an exceptional out- 

 break of wireworms in Czicho-Slovakia, the chief species concerned 

 being Agriotes ustiilatus. Most of the damage occurred in fields of 

 winter grain, though spring grain, clover and turnips were also 

 attacked. The measures recommended include heavy rolling and 

 dusting the ground with slaked lime or kainit.

The drying and shrivelling of the ears of corn, particularly wheat, 

 though rye and oats were also attacked, is reported from many places 

 in Czecho-Slovakia. It is attributed to various causes, one of the 

 chief being Limothrips {Thrips) cerealium, Stenothrips graminum being 

 also present. The damage was particularly severe owing to the weather 

 conditions. The measures recommended are burning over small 

 fields and deep ploughing.

The Phloeothripid, Thaumatothripsfroggatti, gen. et sp. n., is described 

 from New South Wales, where it causes galls on Casuarina cambagei. 

 These are different from the galls usually caused by thrips, the whole 

 development of the insect taking place in them.
