Observations indicate that the mere fact of oviposition into the larva 

 of P. brassicae causes the latter to decompose and liquefy, contrary 

 to the action of the Tachinid, CompsiUtra concinnata, Meij^., which 

 causes it to dry up. Further observations on the nature of the 

 parasitism by D. ruhrostriata are required. 



Phora chlorogastra, Beck., of which one individual was reared at 

 the same time as the Drosophila, is a rare southern species, which 

 seems also to have become acclimatised in the Lvons district.

The insect pests of the pineapple in Cuba are an ant, Sole}iopsis 

 geminata, F., and a Coccid associated with it, Pseudococcus citri, Risso. 

 They may be combated by spraying with an insecticide made up with 

 18 parts water and 1 part of an emulsion containing kerosene 2 gals. 

 [U.S. ?], crude carbolic acid | pint, caustic potash soap h lb., and 

 water 1 gal. This spray must not be applied when the fruit is 

 forming.

The study of insect pests of cranberries was continued [R.A.E., 

 A, ix, 49]. Hitherto unknown parasites of Crambus hortuellus (cran- 

 berry girdler) were reared. A new measure adopted against this 

 moth was spraying with nicotine sulphate. It was found that this 

 method was also successful against leaf-hoppers and spring-tails, 

 which are usually abundant on bogs that are not reflooded, and 

 which probably reduce the vitality of the plants considerably. Satis- 

 factory results were obtained with nicotine sulphate sprays against 

 Rhopobota vacciniana (black-head fire worm). Epelis trimcataria var. 

 faxonii (brown span worm) was unusually prevalent and appeared 

 on more bogs than in 1919. Remedial measures were, as a rule, 

 promptly applied, so that little harm was done, except on a few 

 neglected bogs. Cymatopliora sulphurea (green span worm) was also 

 unusually abundant and completely destroyed a very promising crop 

 covering several acres. Trichogramma minutum, the egg-parasite of 

 the cranberry fruit worm [Mincola vaccinii] was less prevalent than 

 usual.
