Internal parasites of Diaspis pentagona, A. Berlese {B(jI. Ilffic. Min. Ayr., 

 Indus, c Coin. llioni(\. .'/ {I!ll)(i). .Vo. 7. />/;. (ICl (Ki'i). — lUtispis prnlayaita is 

 recognized as a serious pest of iiuili>crries. and some attention is liein^; i^iven to 

 the enconraspnicnt of jiarasitcs of tliis insect. 



On the parasites of Diaspis pentagona, L. (). Howard (/•;»/. .Acfrv, 11 {1906), 

 -Yo. N. pp. .ii>l-2i>.i, fiy. 1). — I). pciiiayoHa has been known in tlie District of 

 CoUinibia since 1892. and an o])portunity has, therefore, l)een had to study rather 

 closely its insect parasites. A number of infested scale have been sj^nt to 

 Italy in the hope that beneficial i)arasites mi.ijht be reared from them to assist 

 in combating the pest in that country. A considerable number of parasites have 

 been reared, one of which is described as new under the name Prospalta 

 hrrle«i. 



The mango weevil (Cryptorhynchus mangiferae), I). L. Yan Dine {Hawaii 

 ,Sta. Press Bill. 11. pp. It. i)lx. i). — The injury done by tlie nningo weevil to the 

 seeds of mangoes was tirst noted last year and the pest has already become a 

 serious one. Apparently it has been introduced into Hawaii some time since 

 ]S!)8. 



The hal)its and life history of the ])est are briefly described. The weevil 

 undergoes its entire development within the seed and can not, therefore, be 

 treated by ordinary insecticides. It is stated that the destruction of rubbish 

 about the trees during the i)eriod from October to March will kill many of the 

 hibernating weevils. It is also recommended that neglected trees along the 

 wayside he destroyed. 



The oyster-shell bark-louse, (i. Quinn {-Jour. Dcpt. Ayr. So. Aust., 8 {1905), 

 Yo. 11, pp. 6.39-6 'il, pys. ,3). — It is not known when the oyster-shell bark-louse 

 was first introduced into South Australia, but apparently it has l)een present 

 for many years. A detailed account is given of the life history of this insect 

 and the injuries which it produces. 



In spraying for the pest the author recommends the use of lime-sulphur-salt 

 wash, various resin compounds, kerosene emulsion, and red oil emulsion. The 

 last-named insecticide is made of 1 lb. soap, 1 gal. red oil, and 1 gal. soft water, 

 the nuxture being dihned before si)raying to 14 to 1(1 gal. 



The oyster-shell bark-louse, T. 1). Jarvis {Caiiad. Ent.. 38 {1906), Yo. .9, 

 pp. 2S9-29.'i. fiys. ,?). — The a])pearance, habits, and life history of this insect are 

 l)riefl.v discussed by way of c()mi)arison with scurfy scale and San Jose scale. 

 \Yhile a number of (>f1icient femedies are known for this pest, the be.st results 

 have followed the use of lime-sul])hur-salt wash. 



A new species of fungus parasitic on Ceroplastes rusci, A. Berlese {Redia, 

 II {1906). \(). .'//. pp. 166-168). — In western Africa, particularly in Dahomey, a 

 scale insect was observed in large numbers on the cocoanut i)alm which jiroved 

 to be Asjiidiotus dcstriicUir. A mi.xture containing soda ;ind resin is recom- 

 mended as a si)ra.v for this i»est. 



A new species of fungus parasitic on ceroplastes rusci, A. Berlese {Redia, 

 3 {1905), No. 1. pp. 8-15. pi. 1. fiys. .1). — In the body cavity and various organs 

 of a number of scale insects, including Ceroplastes nisei, fungus bodies are 

 found resembling yeast cells. The fungus is descrilied as lunv under the name 

 Oospiira sacea rd ia iia. 



Ladybirds and woolly aphis, D. L. Bree.n {-lour. Dipt. Ayr. West. Aii.^t.,
