1915 it was found on all the cotton fields on the Island of Oahu, and 

 on part of Hawaii. The larva is externally parasitic on the full- 

 grown larva of Gelechia gossypiella, but is not an effective check, 

 destroying only a small percentage, though is it equally active indoors 

 among seeds and in the bolls in the fields. This species has been referred 

 to as Goniozus cellularis, Say, in Hawaiian literature.

 News, Barbados, xvi, no. 389, 24th March 1917, p. 90. 



Tomaspis saccharina, Dist., found on sugar-cane in Grenada, is 

 considered to be the same species as that found in Trinidad. It has 

 evidently been established in Grenada for some years, fields that have 

 been under pasture being apparently the most heavily infested. Con- 

 ditions favourable to the pest seem to occur in those fields where 

 there is no excessive amount of moisture, but which are not extremely 

 dry. In Trinidad the planting of cover-crops to keep down grass has 

 been recommended, or a border of about 100 feet can be planted on 

 abandoned fields adjacent to canes. Clean cultivation reduces the 

 number of froghoppers. The larvae of the Syrphid, Salpingogaster 

 nigra, Schin., exercise a considerable degree of control on the frog- 

 hopper nymphs in Trinidad, where they have been artificially bred 

 and distributed, but these are not present in any numbers in Grenada. 

 Metarrhizium anisopliae is a natural enemy of this pest in Trinidad 

 and spores of this fungus have been distributed over infested fields in 

 Grenada ; the results of this experiment are not yet known. Other 

 natural enemies are Attid spiders and the predaceous grasshopper, 

 Xiphidium sp., both of which are scarce in Grenada. The infestation 

 of froghoppers is not at present severe, but will need to be kept under 

 observation. 



Preliminary Trials with Cacao Thrips Fungus. — Agric. News, Barbados, 

 xvi, no. 389, 24th March 1917, p. 94. 



In experiments with cultures of Sporotrichum globuliferum sent from 

 St. Vincent to Grenada for the control of thrips, a number of parasi- 

 tised nymphs and adults were obtained from cacao plants in boxes 

 which had been supplied with thrips in all stages and then sprayed 

 with the fungus. Experiments with the fungus, Metarrhizium aniso- 

 pliae, were inconclusive. It is proposed to repeat these experiments 

 and to make field trials in humid situations when the wet season 

 infestation begins.
