HAWAII INSECT REPORT 



General Vegetables - PEPPER WEEVIL (Anthonomus eugenii) moderate in 0.5 acre of 

 sweet pepper at Wailua, Kauai. (Ikehara) . BEAN FLY (Melanagromyza phaseoli ) 

 negligible in most commercial snap bean plantings at Waimanalo, Oahu; light to 

 moderate in 5,000 square-foot planting of long beans, about 20 percent of leaf 

 petioles infested. On Kauai, infested cowpea and snap bean material collected 

 from various areas revealed 81 percent parasitism of bean fly, mostly by Opius 

 spp. (73 percent). On Maui, bean fly activity remains generally light especially 

 at higher elevations (500+ feet). Infested yardlongbeans collected from Puunene, 

 Waikapu, and Waihee, Maui, revealed 63 percent parsitism; 37 percent by Opius 

 spp. (braconids) . (Sugawa, Miyahira, Kawamura) . 



Fruits and Nuts - Damage by COCONUT LEAFROLLER ( Hedylepta blackburni ) moderate to 

 about 60 percent of fronds of 40+ coconut trees at Hawaii Kai Golf Course, Oahu; 

 damage reported heavy to coconut seedlings at Waimanalo Beach Park (CEIR 21(21): 

 365) apparently contributing to demise of few plants. Cocoons of hymenopterous 

 parasites moderate on infested leaflets at both locales. (Kawamura). COCONUT 

 SCALE ( Aspidiotus destructor ) generally trace in most papaya and banana plantings 

 on windward Oahu. In most fields, about 10 percent of leaves of both crops with 

 spotty, sporadic colonies. (Au, Kawamura). 



Forest and Shade Trees - Larvae and adults of a BARK BEETLE ( Xylosandrus compactus ) 

 moderate in koa haole (Leucaena leucocephala ) terminals at Kipapa Gulch, Oahu; 

 25-50 percent of young plants infested. All stages light to moderate in twigs of 

 Acacia koa at Waiakea Forest Reserve, Hawaii. (Laemmlen, Kashiwai) . 



Miscellaneous Pests - All stages of GIANT AFRICAN SNAIL ( Achatina f ulica ) moderate 

 and active at Schofield Barracks, Oahu, following light rainfall in area; snails 

 in aestivation 2 weeks ago. All stages heavy in drainage basin at Wheeler Air 

 Force Base, Oahu; as many as 500 snails observed at base of and on trunk of Ficus 

 glomerata tree, ROSY PREDATOR SNAIL (Euglandina rosea ) and a CARNIVOROUS SNAIL 

 ( Gonaxis quadrilateralis ) trace at both areas. G. quadrilateral is released at this 

 locality for first time March 24, 1971. On Kauai, no snail activity observed at 

 Poipu or Wahiawa during routine surveillance; poison bait application temporarily 

 discontinued. (Olson, Sugawa) . Sweeping of roadside Koa haole moderately defoliated 

 by a GEOMETRID MOTH ( Semiothisa santaremaria ) and KOA HAOLE LOOPER ( Anacamptodes 

 f ragllaria ) revealed light to moderate larval counts of both species~j 46 S . 

 santaremaria, 27 A. fragilaria per 50 sweeps. (Kawamura).
