The pineapple mealybug ( Pseudo coccus "brevipes Ckll.) is found more 
frequently in cane fields than formerly, though it is not to "be considered 
of particular importance. It continues as an important pest in oineapple 
fields, where cultural practices and spraying methods have "been perfected 
for its control. 
The avocado .mealybug ( Pseudococcus nipae Mask. ) was nowhere observed 
during the year,' either on avocado, fig, or mulberry, which were al?ays so 
thoroughly infested before the introduction of the parasite Pseudaphycus 
utilis Timb. from Mexico in 1922. 
The Mediterranean fruit fly ( Ceratitis canitata Wied.) has been about 
as prevalent as for the past few years. If anything, the infestation of 
mangoes and guavas has been a little less, and coffee is particularly free 
from infestation. 
The coconut leafroller ( Omiodes blackburni Butl.) has been sufficient- 
ly controlled by its parasites in Honolulu and vicinity so that the coco- 
nut trees have a fine appearance with perfect leaves. On the windward 
side of the island, however, the coconut leaves are very ragged, owing 
to ravages of the caterpillars, probably because their parasites are not 
working so favorably there. On the islands of Kauai and Maui, too, the 
coconut leaves are badly infested. 
The corn ear worm ( Heliothis obsoleta Fab.) has been unusually preva- 
lent. Nearly every ear of sweet corn is found attacked by one or more 
caterpillars. 
A mirid bug, Engytatus geniculatus Reut., is always present on tomato 
vines. It is reputed to destroy some of the flower buds, thus lessening 
the crop. 
The tomato pin worm ( Gnori mo schema lyco^ersicella Busck) is usually 
present on tomato leaves, but not to cause particular injury. 
The potato tuber moth ( Gnorimo schema opcrculella Zell. ) is becoming 
of more importance as a pest on the potato tubers. It has been present 
for a long time, but operated chiefly as ate-f "miner on potato, tomato, 
tobacco, Datura, etc. 
The taro leafhopper ( Mogamelus nroserpina Kirk.) was not to be found 
this year in the Waianae district, where taro was found badly infested 
the previous year. At that time (the first appearance of this insect in 
Hawaii) efforts were made to eradicate it and apparently success was at- 
tained. 
The melon fly ( Bactrocera cucurbitae Con.), although prevalent, must 
have been fairly well controlled by its parasite Opius f letcheri Silv., for 
an unusually good crop of melons was produced and the season was quite 
prolonged. 
The rose beetle ( Adoretus sinicus Bum. ) has been prevalent as usual 
as a garden pest. Although Scolia wasps parasitize its grubs, yet no ap- 
parent control is attained. Efforts are being made to introduce additi- 
tional nrasites. Many hundreds of cocoons of Tiphia lucida Ashm. have 
been received from the Philippines. The wasps are slow about developing,
