Tea in Japan suffers scarcely any injury from insect and fungous 

 pests. The former are represented by leaf-rollers, Aphids, and cater- 

 pillars. The robustness of the Chinese tea-plant, the presence of 

 natural enemies, such as spiders, and the severe winters, are the 

 reasons given for this immunit}'.

Very little information can be given regarding insect pests of tea 

 in Burma. A borer, Zeuzera coffeae, and a scale, Aspidiotus trans- 

 parens, occur there. Helopeltis does not appear to have been recorded.

PhyUotreta utana, sp. n., from Utah, Nevada and Oregon is described. 

 Like other beetles of this genus, it attacks and undoubtedly breeds 

 on cruciferous plants, and is at least a potential pest. It was abundant 

 on sugar-beet in a field overgrown with hedge mustard, on which it 

 was also taken. 



McDonald (R. E.) & Tanquary (M. C). Report on the Pink Boll- 

 worm Situation in Mexico.— Af^A/y. News Bull., Texas Dept. 

 Agric, Austin, iii, no. 5, February-March 1921, pp. 6-7. 



This report was made as the result of a visit — from 26th November 

 to 1st December 1920 — to the Laguna region of Mexico. Certain 

 limited areas in Texas and Louisiana are now infested with Platyedra 

 gossypiella, and this infestation came from Mexico. 



Counts, made with care so as not to exaggerate the damage, showed 

 a pink bollworm infestation ranging from 38 to 83 per cent. Other 

 cotton pests include the cotton boll weevil [Anthonomns grajidis], 

 which appears to have been present for 25 years or more, but does not 

 do much injury, probably owing to the arid climate ; melon Aphids, 

 which sometimes infest young cotton in spring and retard growth ; 

 and a species of thrips. The common bollworm, Heliothis ohsoleta. 

 and the leaf worm, Alabama argillacea, are of scarcely any importance. 



In the year 1911 a planter near Monterey, Mexico, brought 125 

 sacks of cotton seed from Egypt, and the pink bollworm evidently 

 reached the Laguna region from this source. There was probably a 

 slight infestation in 1913, but no notice was taken of it. During 1920 

 the damage has been very severe, and the infestation seems to be
