Mealybugs and the spread of grapevine leafroll-associated virus 3 (GLRaV-3) in a New Zealand vineyard
TLDR
The data indicated that GLRaV-3 did not spread into the new block when third generation mealybug populations in adjacent infected vines were lower than ∼5 mealybugs/leaf, and infection in any vineyard probably occurs by all three methods.
Survey of alternative host plants for Kelly's citrus thrips (Pezothrips kellyanus) in citrus growing regions.
Kelly’s citrus thrips (Pezothrips kellyanus) (KCT) has recently been identified as the most serious pest affecting citrus production in New Zealand. A literature survey was undertaken to determine
Review of the risk factors associated with kiwifruit bacterial canker caused by Pseudomonas syringae pv. actinidiae
TLDR
A review of the epidemiological risk factors that are associated with Psa disease within orchards in New Zealand and a range of known and postulated risk factors for the development of bacterial canker in kiwifruit are described.
LIFE TABLE COMPARISON BETWEEN THE PARASITOID THRIPOBIUS SEMILUTEUS AND ITS HOST GREENHOUSE THRIPS
TLDR
Results suggest that T. semiluteus has the potential to reduce population levels of greenhouse thrips if released into New Zealand if imported into quarantine from California.
DISTRIBUTION AND NEW HOST RECORDS FOR COSMOSPORA AURANTIICOLA AND COSMOSPORA FLAMMEA: ENTOMOPATHOGENS OF DIASPIDIDAE IN NEW ZEALAND
TLDR
Two important species of fungal entomopathogens recorded on armoured scale insects in New Zealand are Cosmospora aurantiicola (Fusarium larvarum) and C. coccophilum (F. fl ammea).
EFFECTS OF GREENHOUSE THRIPS (Heliothrips haemorrhoidalis) LIFE-STAGE, DENSITY AND FEEDING DURATION ON DAMAGE TO AVOCADO FRUIT
TLDR
The results suggest that a thrips monitoring system should distinguish between adult and larval thrips, and there is potential to predict the accumulation of feeding damage over time for any given thrips population level.
Effects of adult feeding on longevity and fecundity of Ctenopseustis obliquana (Lepidoptera: Tortricidae)
TLDR
It is concluded that the provision of nectar sources within orchards is not likely to increase the reproductive capacity of C. obliquana but the suitability of any new plants as hosts for larval C. ObliquANA needs to be evaluated.
ESTIMATING THE HOST RANGE OF A THRIPS PARASITOID
New Zealand has recently adopted new legislation (The Hazardous Substances and New Organisms Act [HSNO] of 1996) governing the importation and release of new organisms, including insect biological
A POTENTIAL BIOLOGICAL CONTROL AGENT FOR GREENHOUSE THRIPS
TLDR
Greenhouse thrips (Heliothrips haemorrhoidalis) damage citrus, avocados and ornamental plants in New Zealand and a potential biological control agent, Thripobius semiluteus, has been imported into quarantine from California.
