At the request of the Government of Niue the USDA Forest Service Institute of Pacific Islands
Forestry conducted a survey of invasive plant species of environmental concern. The survey was similar to those previously conducted in Micronesia and American Samoa. Conducted during the period May 15-19, 2000, the main objectives of the survey were: "Identify plant species that are presently causing problems to natural and semi -natural ecosystems; identify species that, even though they are not presently a major problem, could spread more widely or are known to be problem species elsewhere; and confirm the absence of species that are a problem elsewhere
1

and, if introduced in Niue, could be a threat; and make appropriate recommendations." A report on the study prepared by Jim Space and Tim Flynn can be found online at http://www.hear.org/pier/niuereport.htm

SOUTH AFRICAN INSECTS MAY HELP AGAINST CAPE IVY
(Source: Agricultural Research Magazine , June 2001, article by Kathryn Barry Stelljes)

.
"A fly and a moth from South Africa may soon be enlisted to help protect natural treasures in
California, Oregon, and Hawaii. That's because these insects might serve as biological control agents for Cape ivy, Delairea odorata ." Introduced here in the 1800's it now "infests prized natural coastal areas in California up into Oregon and native upland forests on the island of
Hawaii. Willow-dominated riparian areas in California have been among the most overrun so far." The two insects (Cape ivy gall fly, Parafreutreta regalis and a tiny moth, Acrolepia sp.
) will be tested in quarantine for approximately 3 to 4 years to make sure they don't feed on desirable plants.

COMPARATIVE FEEDING AND DEVELOPMENT OF Pseudoplusia includens
(LEPIDOPTERA: NOCTUIDAE) ON KUDZU AND SOYBEAN FOLIAGE

"Abstract - Kudzu, Pueraria Montana (Lour.) Merr. variety lobata (Willd.) Maesen & Almeida, a close relative of soybean, Glycine max (L.) Merr., is an adventive and widely distributed weed in the southeastern United States. Conventional wisdom says that native arthropods do not feed heavily on kudzu, but recent evidence has indicated this is not the case. To better understand the interaction of kudzu and native insects, the biology of the soybean looper, Pseudoplusia includens (Walker), was compared on kudzu and soybean. Insects fed on kudzu had higher mortality, longer development times with supernumerary molts, and lower pupal weights than those fed on soybean. Rearing for up to three ge nerations on either plant host had an effect on length of development time but did not affect other measured parameters. Foliage consumption did not differ between treatments, and nutritional quality of soybean and kudzu did not differ.
The instar at which insects were transferred from artificial diet to either kudzu or soybean significantly influenced development time, number of instars, foliage consumption, and pupal weights, with instar 4 being the optimum stage for transfer. In an oviposition test, females readily oviposited on kudzu in a no choice test, but when both kudzu and soybean were provided,
2

more eggs were deposited on soybean than on kudzu. Our studies show that although kudzu is an acceptable host, soybean is a preferred and better quality host."

FIRE ANT PROJECT
(916) 454-0817 pskyler@fs.fed.us
(Source: June 1, 2001 article by Tom Lollis, Clemson University)
"Columbia - Scientists from Clemson University and the USDA are pleased with the first year of a project that puts natural biological warfare into the battle against the red imported fire ant
(RIFA)." As part of the project, scientists traveled to South America "looking for some of the baggage the ants left behind - pathogens and predators. Thelohania solenopsae and the phorid fly are two of the natural enemies they brought back to the United States." According to Mac
Horton, Clemson Extension/Research entomologist "it will take two to three years for either organism to reach a population density strong enough to begin significant expansion."
"Horton said scientists believe that the two biological agents, released in 11 states infested with imported fire ants (IFA), and other biological controls being looked at, could eventually reduce overall IFA populations by 50-60 percent by natural means."

HUMAN HEALTH
INTEGRATED PEST MANAGEMENT AND ALLOCATION OF
CONTROL EFFORTS FOR VECTOR-BORNE DISEASES
(Howard S. Ginsberg)
(Source: Journal of Vector Ecology 26(1):32-38, June 2001). Available online at http://www.sove.org/june2001/ginsberg.pdf
.
"Abstract: Applications of various control methods were evaluated to determine how to integrate methods so as to minimize the number of human cases of vector-borne diseases. These diseases can be controlled by lowering the number of vector-human contacts (e.g., by pesticide applications or use of repellents), or by lowering the proportion of vectors infected with pathogens (e.g., by lowering or vaccinating reservoir host populations). Control methods should be combined in such a way as to most efficiently lower the probability of human encounter with an infected vector. Simulations using a simple probabilistic model of pathogen transmission suggest that the most efficient way to integrate different control methods is to combine methods that have the same effect (e.g., combine treatments that lower the vector population; or combine treatments that lower pathogen prevalence in vectors). Combining techniques that have different
3

effects (e.g., a technique that lowers vector populations with a technique that lowers pathogen prevalence in vectors) will be less efficient that combining two techniques that both lower vector populations or combining two techniques that both lower pathogen prevalence, costs being the same. Costs of alternative control methods generally differ, so the efficiency of various combinations at lowering human contact with infected vectors should be estimated at available funding levels. Data should be collected from initial trials to improve the effects of subsequent interventions on the number of human cases."

DIAZINON; RECEIPT OF REQUESTS FOR AMENDMENTS
AND CANCELLATIONS
(Source: Environmental Protection Agency, Notice, Federal Register May 30, 2001, Vol. 66, No.
104, pp. 29310-29313)
"Summary: The companies that manufacture diazinon [O, O-diethyl O-(2-isopropyl-6-methyl-
4-pyrimidinyl) phosphorothioate] for formulation of pesticide products containing diazinon have asked EPA to cancel their manufacturing-use product registrations. In addition, these companies have asked EPA to cancel or amend their registrations for end-use products containing diazinon to delete all indoor and certain agricultural uses. Pursuant to section 6(f) (1) of the Federal
Insecticide, Fungicide, and Rodenticide Act (FIFRA), EPA is announcing the Agency's receipt of these requests. These requests for voluntary cancellation were submitted to EPA in February and
March 2001. EPA intends to grant the requested cancellations and amendments to delete uses.
EPA also plans to issue a cancellation order for the deleted uses and the canceled registrations at the close of the comment period for this announcement. Upon the issuance of the cancellation order, any distribution, sale, or use of diazinon products listed in this notice will only be permitted if such distribution, sale, or use is consistent with the terms of that order."

(General Technical Report, PNW-GTR-495, Septe mber 2000, USDA Forest Service, Pacific
Northwest Research Station) Available online at http://www.fs.fed.us/pnw/pubs/gtr495.pdf
)
"Abstract - In 1998, forest vegetation was monitored for ozone injury on permanent plots in two
Sierra Nevada national forests in California, at three locations in Mount Rainier National Park in
4

Washington, and at 68 forest health monitoring (FHM) locations throughout Washington,
Oregon, and California. This was the first year that extensive monitoring of forest vegetation for ozone injury was carried out in Oregon and Washington. Injury was detected on ponderosa and
Jeffrey pine in the Sierra Nevada permanent plots and on red elderberry at one FHM location in southwest Washington. No injury was detected at the Mount Rainier sites. We also report on results of a trial where red alder, huckleberry, blue elderberry, and chokecherry were exposed to ozone under controlled conditions."

(Source: Journal of Vector Ecology 26(1):7-14, June 2001). Available online at http://www.sove.org/june2001/mantooth.pdf
.
"Abstract: The purpose of this study was to increase our knowledge of the geographic distribution and natural host range of hantaviruses in Texas, southeastern New Mexico, and
Mexico. Blood samples from 3,255 wild rodents representing 34 species, were tested for hantavirus antibody (IgG), using an enzyme-linked immunosorbent assay. Hantavirus antibody was found in one or more rodents from each of 13 counties in Texas, Otero County in southeastern New Mexico, and Mexico State (central Mexico). The 133 antibody-positive rodents included seven Peromyscus species ( P. attwateri, P. boylii, P. hylocetes, P. leucopus, P. maniculatis, P. melanotis, and P. pectoralis ), Sigmodon hispidus, Oryzomys palustris, two
Reithrodontomys species ( R. fulvescens and R. megalotis ), Neotoma albigula , and Perognathus merriami . This study provides further evidence that rodent-associated hantaviruses are geographically widely distributed in Texas. The discovery of antibody in P. hylocetes and P. melanotis is evidence that peromyscine rodents in Mexico are naturally associated with viruses belonging to the genus Hantavirus ."

REPELLENCY OF VOLATILE OILS FROM PLANTS
AGAINST THREE MOSQUITO VECTORS
(A. Tawatsin, S.D. Wratten, R.R. Scott, U. Thavara, and Y. Techadamrongsin)
(Source: Journal of Vector Ecology 26(1): 76-82, June 2001). Available online at http://www.sove.org/june2001/tawatsin.pdf
"Abstract: Volatile oils extracted by steam distillation from four plant species (turmeric
( Curcuma longa ), kaffir lime ( Citrus hystrix ), citronella grass ( Cymbopogon winterianus ) and hairy basil ( Ocimum americanum )), were evaluated in mosquito cages and in a large room for
5

their repellency effects against three mosquito vectors, Aedes aegypti, Anopheles dirus and Culex quinquefasciatus . The oils from turmeric, citronella grass and hairy basil, especially with the addition of 5% vanillin, repelled the three species under cage conditions for up to eight hours.
The oil from kaffir lime alone, as well as with 5% vanillin added, was effective for up to three hours. With regard to the standard repellent, deet alone provided protection for at least eight hours against Ae. aegypti and Cx. quinquefasciatus , but for six hours against An. dirus.
However, deet with the addition of 5% vanillin gave protection against the three mosquito species for at least eight hours. The results of large room evaluations confirmed the responses for each repellent treatment obtained under cage conditions. This study demonstrates the potential of volatile oils extracted from turmeric, citronella grass and hairy basil as topical repellents against both day- and night-biting mosquitoes. The three volatile oils can be formulated with vanillin as mosquito repellents in various forms to replace deet ( N,N -diethyl-3methylbenzamide), the most common chemical repellent currently available."
