LtJSTNER (G.). Incvrvaria (Lampronia) rubiella, injurious to the Rasp- 

 berry {Riibus idaeus) in Germany. — MtJdy. Bull. Agric. Intell. &

The injury caused to raspberry canes by Incurvaria rubiella, Bjk., 

 may be checked by removing and burning the attacked shoots. In the 

 spring, when the new shoots are growing, several buds lying one above 

 the other fail to develop. They at first retain their green colour, but 

 later on turji brown, wither and finally fall or decay. As a consequence, 

 the foliage of the new shoots is very scanty and thin. As these symp- 

 toms will occur at the beginning oi spring, they are likely to be confused 

 with those produced by the cold. If a shoot bearing buds which have 

 failed to develop be cut in half, a gallery may be seen which runs from 

 the pith towards the bud and is the work of the larva of this pest.

A proclamation recently issued in South Australia enacts that no 

 fruit of any tree or plant shall be introduced into South Australia from 

 the States of Queensland, New South Wales, and Western Australia, 

 in the Commonwealth of Austraha, unless accompanied by a certificate, 

 signed by an Inspector of orchards stationed in the district wherein 

 such fruit was gi'own in the exporting State, setting out and declaring 

 the following facts :■ — {a) That no fruit-fly has been known to exist 

 for the two years previous to the signing of such certificate in the 

 orchard from whence such fruit was picked or packed. (6) That no 

 fruit-fly has been known to exist in any orchard or garden within five 

 miles of the land on which the said fruit was grown. 



The New Zealand regulation requires a declaration that no fruit-fly 

 is known to exist in, or within one mile of, the orchard where the fruit 

 was grown. 



Bali.ott (H. a.). Report by the Entomologist. — Dept. Agric. for the 

 West Indies, St. George, Grenada, 26th April 1915, 11. pp. 

 [Received 24th July 1915.] 



The following observations were made during a visit to (Ircnada in 

 February and March 1915 : Heliotkrifs rubrocinctus (cacao thrips) is 

 permanently present and generally distributed in Grenada, and occurs 

 year after year in the same localities, in the same portions of the cacao 

 plantation and perha])s on the same trees. It is most abundant during 

 the last three months of the year in those estates which lie on the lower 

 lands around the periphery of the island ; in the dry months a con- 

 siderable improvement in the condition of the trees takes place. This 

 is contrary to the state of affairs prevailing in other countries. In 

 Grenada thrips may be present in cacao for several years and never 

 increase in nimibers sufficiently to attract attention. The attacks 

 of thrips indicate that something is wrong with the plant or with 

 the conditions imder which it is growing. The patches examined 

 suffered from root disease, bad drainage or unfavourable soil conditions.
