Pseudococcus calceolariae, P. sacchari, and Aspidiotus sacchari, and 

 the termites, Coptotermes marabitanus, Hag., and Eutermes hatiensis, 

 Holmg., the latter being a local species. 



Stenocranus (Delphax) saccharivorus (cane fly), a very serious pest 

 in Jamaica, has not been observed in Barbados since 1914, when its 

 eggs on cane leaves were heavily parasitised by the Mymarid, Anagrus 

 Jlavescens. 



Cotton was subject to small local attacks by Eriophyes gossypii 

 (blister mite) and by Alabama argillacea and Aletia luridula (cotton 

 caterpillars), which, however, were held in check with Paris green. 

 Injury to the stem by Porricondyla gossypii (red maggot) was recorded 

 from one locality during the year. 



In several districts complaints were received of injury to sweet 

 potatoes by Euscepes batatas (scarabee), the remedy for which lies in 

 much improved methods of clean cultivation, such as planting from 

 sound tubers only, and the removal and destruction of all infested 

 material from the fields after harvesting. 



Tetranychus telarius w^as present to some extent during the dry 

 months. In cases where treatment was necessary dusting with 

 flowers of sulphur and lime in about equal parts helped to control it. 



Diaprepes abbreviatus was found severely attacking young potato 

 plants grown as a rotation crop after infested cane. The stems 

 below ground were bored so as to result in the death of the plants. 

 Less susceptible plants, such as cotton or cassava, should be used in 

 such cases as a rotation crop. 



Peregrinus maidis, Ashm., was collected from sorghum leaves 

 during the year. 



Garden plants and citrus were found to be attacked by : — Lepido- 

 saphes beckii, Newm., Chionaspis citri, Comst., Pseudococcus citri, 

 Risso, and Coccus viridis, Green, the control of this last being attempted 

 in one place by spraying with the fungus, Cephalosporium, lecanii. 

 A parasite of Chrysomphalus dictyospermi, Morg., was bred out and sent 

 for identification. A species of Diaspis, probably D. echinocacti, 

 was collected on cactus. A species of Aspidiotus, probably A. rapax, 

 was collected on oleander. Two Cerambycids, Achryson surinamum 

 and Chloridaf estiva, were bred in large numbers from the trunk of an 

 ebony tree. A thrips, probably Thrips tabaci, seriously infested 

 eschalot leaves in one locality. The Ptinid, Cathorama herbarium, 

 Gorh., was found eating into books and upholstered furniture. The 

 Curculionids, Promecops lunatus and Artipus corycaeus, attacked bean 

 leaves and the seed pods of Abrus precatorius respectively. The 

 Scolytids, Xyleborus confusus and Pycnarihrum pallidum, were obtained, 

 the latter from the bark of Ficus nitida. 



Nezara viridula (green bug) has been reported as causing damage 

 to tomato plants, laying eggs in clusters on the foliage and sucking 

 the juices of the leaves and fruit. This pest can be controlled by 

 hand-picking the eggs and adults. The larvae of Prodenia dolichos 

 and Pacliyzqncla bipunctalis caused great injury to the foliage of 

 certain ornamental plants. A species of termite infesting wooden 

 buildings has been identified as Phinotermes nasutus, Perty. 



Species added to the collection of Barbados insects include the 

 Tenebrionid, Opatrinus gemellatus, recorded as attacking young 

 cotton plants in some of the other West Indian Islands.
