During the annual period July 1917-1918, no new work was under- 

 taken owing to the War, but the beneficial insects previously introduced 

 were propagated and distributed without interruption, although there 

 is abundant proof of their establishment. The reason for this is that 

 there is a tendency, especially in the case of insects of weak flight, 

 to disappear in isolated districts in the absence of their hosts. Hence 

 it has been the practice to stock new fields of maize with Paranagrus 

 oshorni (corn leaf-hopper parasite) when the plants were about a foot 

 high, or to use a catch crop to multiply the parasite. 



The number of beneficial insects liberated during 1917 was : — 

 Fruit-fly parasites, 16,798 ; Spalangia catneroni (horn-fly parasite), 

 60 ; Ojnus fletcheri (melon-fly parasite), 16,815 ; Paranagrus osborni 

 (corn leaf-hopper parasite), 109,611. 



The total parasitism of the fruit-fly. during the year showed an 

 increase of about 10 per cent., a fact correlated with the greater 

 abundance of some fruits, such as Kona oranges, on the markets. 



During the month of April 1918, the insectary handled 20,300 

 pupae of the melon fly [Dacus cucurbitae'], from which 1,497 

 individuals of Opius fletcheri were bred and distributed.

During 1917 a new building was erected for the Division of Plant 

 Inspection with fumigation vaults separate from the main building, 

 and equipped with an incinerator. 



The usual number of dangerous insects was mtercepted during 

 the year, including : — Coleoptera, 17 genera, 20 species ; Lepidoptera, 

 7 genera, 7 species ; ants, 7 genera, 10 species ; scale-insects, 10 

 genera, 15 species ; Aphids, 4 genera, 4 species. 



Among the more important pests met with were : — The Argentine 

 ant \Iridomyrmex humilis], discovered on two occasions, while other 

 species that have not as yet gained entrance, together with others 

 already estabhshed, were frequently found ; a weevil, the larvae of 

 which are very destructive to roots of plants found in the soil of a 

 potted plant from Japan ; and bagworms, hitherto unknown in 

 Hawaii, were also found on plants from the Orient. 



During April 1918, a package of palm seeds from Egypt was fumi- 

 gated for an infestation of scale-insects ; a case of fruit and ornamental 

 trees from Japan was fumigated owing to the presence of ants in the 

 packing ; and a package of orchids from Manila was fumigated for 

 an infestation of ants and scale-insects.
