Felt (E. P.). Arthrocnodax constricla, sp. n.—Jl. Econ. Entom., 

 Concord, N.H., vii, no. 6, December 1914, p. 481. 



A description is given of a midge, Arthrocnodax constricla, sp. n., 

 reared from garden beans infested with Tetranychus bimaculatus and 

 probably piedaceous on it.

The work undertaken against cacao beetles [Stirastoma depressum] 

 consisted of spraying and cutting out the larvae, but many planters 

 complained that some of their neighbours did nothing and so rendered 

 their own work ineffective. On one estate, 73,000 larvae and 6,000 

 beetles were caught between the 1st January and the 10th December, 

 1914. 



In connection with cacao thrips [HeUothrips ruhrocinctus], an ex- 

 periment of dusting 1,000 cacao trees Avith a mixture of 1 part flowers 

 of sulphur with 10 parts of air-slaked hme, was tried early in 

 the morning so that the mixture might adhere to the leaves when 

 applied by means of Furet dusters. Although some of the insects 

 were killed, many survived, and it is not considered that dusting can 

 be used with success against thrips.

Agric. Rev., Manila, vii, nos. 10-12, October-December 1914, 



pp. 420-421. 



The Capsid, Helopeltis anlonii, Watrh., is likely to prove one of the 



most serious pests of all anonaceous plants, mangos, and avocados, 



especially in sheltered and shady situations. This bug appears a 



short time before the rainy season begins, and even when in small 



numbers, can do a considerable amount of damage. On cacao, it 



attacks the immature pods, which blacken and drop off. It is doubtful 



whether this pest can be controlled in the nursery, when on the wing, 



but on cacao, where the immature wingless individuals congregate on 



the pods, stems and branches, it is probable that they could be destroyed 



without difficulty by a weak contact spray. 



Clement (F. M.). Plum Culture in Ontario.— On/ano Dept. Agric, 

 Toronto, Bull. no. 226, December 1914, 32 pp., 12 figs. 



In the course of this general treatise on plum culture, Aspidiotus 

 perniciostis (the San Jose scale), Conotrachelus nenuphar (plum 

 curculio), [see this Review, Ser. A, ii, pp. 432 and 458], shot-hole 

 borers and aphids are mentioned as plum pests, the first being the most 

 serious enemy of this tree. Control measures are briefly indicated. 

 Other insects attacking the plum, which are not generally serious, 

 are tent caterpillars {Malacosoma spp.], tussock moth [Hemerocampa], 

 spring and fall canker worms [Paleacrita vernata and Alsophila ponie- 

 taria] and the green fruit worm. A calendar outUning four sprayings 

 concludes this section of the bulletin.
