"Brazilian scale" is a potential biocontrol agent for strawberry guava (Psidium cattleianum). "Brazilian scale" is a potential biocontrol agent for strawberry guava (Psidium cattleianum). Tectococcus ovatus is not known to occur in Hawaii (as of 08 October 2005). Tectococcus ovatus is native to Brazil(?).
Controversy flares over proposal to control waiawi [strawberry guava] with scale insect
"The proposed release of a scale insect to control strawberry guava, or waiawi (Psidium cattleianum), has sparked an outcry of opposition among some sectors of the public. Yet, although the opposition means a delay in the scheduled release, the scientists most closely involved with the project say they welcome the development as an opportunity to educate the public about what they do and the ways in which their plan can work to the state's benefit."

"Opponents of the planned introduction of a biocontrol agent for strawberry guava have raised several arguments. Here are the top concerns, along with the responses from scientists with the Forest Service, the USDA Agricultural Research Service, and others...."
Insect release proposed to control exotic strawberry guava
"U.S. Forest Service scientists with the Institute of Pacific Islands Forestry have submitted a proposal to release a Brazilian insect to control the spread of strawberry guava, a South American tree that has invaded and degraded native Hawaiían ecosystems since it was introduced in 1825 as a garden plant."
Bugs could slow strawberry guava
"Bugs could slow strawberry guava" discusses the possibility of releasing a biocontrol agent (Tectococcus ovatus) in Hawaii to slow the spread of the invasive strawberry guava (Psidium cattleianum). Strawberry guava trees threaten the existence of many native ecosystems in Hawaii.

Host specificity of Tectococcus ovatus (Hemiptera: Eriococcidae), a potential biological control agent of the invasive strawberry guava, Psidium cattleianum (Myrtales: Myrtaceae), in Florida
"In total, 57 plant species representing 21 families were included in the host range tests.... The results of the host specificity tests suggest that [Tectococcus] ovatus is a suitable candidate for classical biological control of strawberry guava in Florida."

Hawaii County Resolution 0809 (regarding ban on biocontrol agents for Myrtaceae on the Big Island [Hawaii])
Hawaii County Resolution 0809 requests a ban on the release of biological control agents on the Island of Hawaii, Including insects, fungi, bacteria, viruses, or other pathogens for any tree species related to ohia (Metrosideros polymorpha), including all species of the family Myrtaceae, such as the strawberry guava (Psidium cattleianum).
Insect released proposed to control exotic strawberry guava

An overview of biocontrol, multimedia gallery, and proposed strawberry guava biocontrol plan are presented by the Institute of Pacific Islands Forestry.
Petition for field release of Tectococcus ovatus (Homoptera: Eriococcidae)
for classical biological control of strawberry guava, Psidium cattleianum Sabine
(Myrtaceae), in Hawaii (10 May 2005)
"Tectococcus ovatus is proposed for release into the environment for biological control of P[sidium] cattleianum in the state of Hawaii. This highly specific insect produces leaf galls on P. cattleianum in its native range in Brazil. It is expected to reduce growth and reproduction of P. cattleianum, thereby limiting spread of the weed and production of fruits available to pest fruit flies...."

Ecology of invasive plant species; their impacts on ecosystems of Hawaii and the Pacific Islands; and their biological control agents
The objectives of the project described here are to (1) increase understanding of invasive plants on native forest ecosystems of Hawaii; (2) develop understanding of biological agents released for invasive weed control; (3) develop biological control agents; (4) increase information on distribution of invasive species; (5) increase information on invasiveness of commonly used plants; (6) increase awareness of the hazards in using invasive plants in landscaping; and (7) increase abilities of agencies to prevent and manage invasive species.
