SoLOMiDEs (Z. G.)- Notes on a Thrips injurious to Vines in Cyprus. — 



Bull. Entom. Research, London, vi, no. 2, September 1915, 

 pp. 197-199. 



Cryjitothrips brevicoUis, Bagnall, sp. n., has been known to vine- 

 growers in Cyprus for the past 10 years, but the actual damage caused 

 by the insect has only recently been recognised. The disease of vines 

 called " Caraoli " has been shown to be due to the action of this thrips. 

 The insect has three generations annually, and between April and the 

 middle of September attacks the tender parts of the vine. The eggs 

 are laid in the buds or near the base of the opening leaves. The larvae 

 on hatching injure these by cutting or scraping the epidermis and 

 sucking the juices. The result of attack is a shortening of the nodes 

 of the stem and the leaves become curled and spotted. The nymphs 

 and adults continue to injure the foliage upon the branches where 

 the attack is localised, the plants meanwhile putting out new 

 branches. Complete destruction in one part is followed by a fresh 

 attack elsewhere. The insect appears at the time of the opening 

 of the leaves ; eggs laid at this time hatch in from two to five 

 days. Vines attacked early present a more injured appearance 

 than do those attacked after the formation of the first shoots. 

 The second generation occurs in May and June, when the flowers 

 and yomig fruit are damaged. Injured fruit either remains small 

 or dries up ; in serious cases, about 50 per cent, may be com- 

 pletely destroyed. New flowers and small fruit may be produced 

 in July and August, but these only serve as food for the third generation. 

 The latter continues until the falling of the leaves, when the adults 

 hibernate in crevices of the stem or branches or in the ground. Certain 

 Acari are parasitic on C. brevicoUis. 



The following preventive measures are recommended : — (1) the 

 removal of all weeds and fallen leaves ; (2) the clearing of old bark 

 from the main stem and the application of lime wash to the stems ; 

 this will kill 80 to 90 per cent, of hibernating insects ; (3) deep plough- 

 ing or digging. When the crop is already afliected, the vines should 

 be sprayed when the first shoots appear with 4 lb. of quassia chips 

 and 3 oz. of Paris green in 27| gals, of water. The spray should be 

 repeated just before the flowers open.
