Abstract:
Epiphyas postvittana nucleopolyhedrovirus (EppoNPV) has considerable potential as a biocontrol agent or biopesticide for control of lightbrown apple moth Epiphyas postvittana a pest of horticultural crops in New Zealand and a market access problem in export fruit To obtain regulatory approval for EppoNPV in either role EppoNPV must not negatively impact on nontarget organisms In this study eight nontarget insect species from one hymenopteran and five lepidopteran families were inoculated with EppoNPV at high titre (109 PIB/ml) Larval survival growth rates pupation and pupal weights were measured and larvae examined for EppoNPV Minor differences in one parameter were found in Helicoverpa armigera and Cydia pomonella but no viral infection Growth and survival were compromised in virusfed individuals in only one species Tyria jacobaeae The majority of T jacobaeae larvae had high microsporidal infections and EppoNPV polyhedra were found in only one larva suggesting a very low likelihood of field infectivity

Abstract:
Feeding by leafroller larvae damages grape bunches and makes them susceptible to Botrytis cinerea disease Leafroller infestation of foliage and bunches and the incidence of botrytis was measured on vineyards in Gisborne Hawkes Bay and Marlborough over 2 years Fortyfour blocks received no leafrolleractive insecticides while 22 were sprayed once preflowering with the selective insect growth regulator tebufenozide Tebufenozide very effectively reduced infestations and gave seasonlong control On leaves untreated blocks averaged 14 leafrollers/search compared with 4 on sprayed blocks Comparative figures for fruit at harvest were 18/100 bunches and 3/100 respectively There was a trend for lower botrytis incidence in blocks where tebufenozide was used Over 99 of the leafrollers reared were Epiphyas postvittana Parasitism of larvae and pupae at 67 on leaves and 50 in bunches was similar in untreated and treated blocks Epiphyas postvittana in vineyards is easily managed using tebufenozide which did not compromise biological control

Abstract:
Life-history parameters and developmental rates of Epiphyas postvittana were determined for four natural food plants and Shorey's diet at each of six temperatures. The rate of development of larvae and the life-history parameters were influenced by both temperature and diet. The highest r(m) value was given by populations feeding on Plantago lanceolata, followed by those on Shorey's diet and Rumex crispus, all at 25 . 2 degrees C, then by Malus pumila at 19 . 9 degrees C and Trifolium repense at 25 . 2 degrees C. Zero population growth occurred at 7 . 1 and 30 . 7 degrees C. A life-table study of five geographical strains of the moth under non-variable conditions (constant temperature and artificial diet) showed that finite rate of increase (lambda) was significantly correlated with climatic features of habitats, viz. mean annual Values of temperature, rainfall and relative humidity. Peak values of lambda occurred at cooler temperatures, moderate levels of habitat moisture and high altitudes (500-1000 m); the Canberra population gave the highest value (lambda = 1 . 157), followed by Armidale (lambda = 1 . 152), Melbourne (lambda = 1 . 141), Mildura (lambda = 1 . 135) and Auckland (lambda = 1 . 118). Higher performance of E. postvittana on herbaceous plants than on woody plants suggests that it primarily evolved as a feeder on herbaceous plants.

Abstract:
The insect growth regulators tebufenozide and fenoxycarb were compared with the industry standard organophosphate, azinphos-methyl, in a replicated field trial. In both the 1992-93 and 1993-94 seasons, the 2 insect growth regulators maintained damage levels to harvested and windfall apples below 1% for both codling moth (Cydia pornonella L.) and lightbrown apple moth (Epiphyas postvittana Walker). This was despite considerable pest pressure as indicated by pheromone trap catches of both species. In the first season of the trial, E. postvittana was controlled more effectively (P<0.05) by tebufenozide than by fenoxycarb. In both seasons, populations of two-spotted mite, Tetranychus urticae Koch, and European red mite, Panonychus ulmi Koch, were higher in plots under azinphos-methyl treatment than in either insect growth regulator treatment. Neither insect growth regulator appeared to suppress populations of the phytoseiids Typhlodromus pyri Scheuten and Typhlodromus occidentalis Nesbitt. Limb jarring in the second season showed statistically significant (P<0.05) differences in populations of other predators which may have contributed to the biological control of phytophagous mites in the insect growth regulator treatments. Numbers of spiders, Stethorus spp., and apple dimpling bug (Carnpylomma liebknechti Girault) nymphs were all lower in the azinphos-methyl treatment. Results are discussed in relation to reducing dependence on conventional pesticides by use of more target-specific compounds which may be more compatible with biological control.

Abstract:
Vineyards worldwide occupy over 7 million hectares and are typically virtual monocultures, with high and costly inputs of water and agro-chemicals. Understanding and enhancing ecosystem services can reduce inputs and their costs and help satisfy market demands for evidence of more sustainable practices. In this New Zealand work, low-growing, endemic plant species were evaluated for their potential benefits as Service Providing Units (SPUs) or Ecosystem Service Providers (ESPs). The services provided were weed suppression, conservation of beneficial invertebrates, soil moisture retention and microbial activity. The potential Ecosystem Dis-services (EDS) from the selected plant species by hosting the larvae of a key vine moth pest, the light-brown apple moth (Epiphyas postvittana), was also quantified. Questionnaires were used to evaluate winegrowers’ perceptions of the value of and problems associated with such endemic plant species in their vineyards. Growth and survival rates of the 14 plant species, in eight families, were evaluated, withLeptinella dioica(Asteraceae) andAcaena inermis‘purpurea’ (Rosaceae) having the highest growth rates in terms of area covered and the highest survival rate after 12 months. All 14 plant species suppressed weeds, withLeptinella squalida, Geranium sessiliforum(Geraniaceae),Hebe chathamica(Plantaginaceae),Scleranthus uniflorus(Caryophyllaceae) andL. dioica, each reducing weed cover by >95%. Plant species also differed in the diversity of arthropods that they supported, with the Shannon Wiener diversity index (H′) for these taxa ranging from 0 to 1.3.G. sessiliforumandMuehlenbeckia axillaris(Polygonaceae) had the highest invertebrate diversity. Density of spiders was correlated with arthropod diversity andG. sessiliflorumandH. chathamicahad the highest densities of these arthropods. Several plant species associated with higher soil moisture content than in control plots. The best performing species in this context wereA. inermis‘purpurea’ andLobelia angulata(Lobeliaceae). Soil beneath all plant species had a higher microbial activity than in control plots, withL. dioicabeing highest in this respect. Survival proportion to the adult stage of the moth pest,E. postvittana, on all plant species was poor (<0.3). When judged by a ranking combining multiple criteria, the most promising plant species were (in decreasing order)G. sessiliflorum, A. inermis‘purpurea’,H. chathamica, M. axillaris, L. dioica, L. angulata, L. squalidaandS. uniflorus. Winegrowers surveyed said that they probably would deploy endemic plants around their vines. This research demonstrates that enhancing plant diversity in vineyards can deliver SPUs, harbour ESPs and therefore deliver ES. The data also shows that growers are willing to follow these protocols, with appropriate advice founded on sound research.

Abstract:
The genome of Anticarsia gemmatalis multiple nucleopolyhedrovirus isolate 2D (AgMNPV-2D), which is the most extensively used virus pesticide in the world, was completely sequenced and shown to have 132 239 bp (G+C content 44.5 mol%) and to be capable of encoding 152 non-overlapping open reading frames (ORFs). Three ORFs were unique to AgMNPV-2D, one of which (ag31) had similarity to eukaryotic poly(ADP-ribose) polymerases. The lack of chiA and v-cath may explain some of the success and growth of the AgMNPV biological control programme, as it may explain the high recovery of polyhedra sequestered inside dead larvae in the field, which are collected and used for further application as biological pesticides in soybean fields. The genome organization was similar to that of the Choristoneura fumiferana defective MNPV (CfDefNPV). Most of the variation between the two genomes took place near highly repetitive regions, which were also closely associated with bro-coding regions. The separation of the NPVs into groups I and II was supported by: (i) a phenogram of the complete genomes of 28 baculovirus and Heliothis zea virus 1, (ii) the most parsimonious reconstruction of gene content along the phenograms and (iii) comparisons of genomic features. Moreover, these data also reinforced the notion that group I of the NPVs can be split further into the AgMNPV lineage (AgMNPV, CfDefNPV, Epiphyas postvittana NPV, Orgyia pseudotsugata MNPV and C. fumiferana MNPV), sharing eight defining genes, and the Autographa californica MNPV (AcMNPV) lineage (AcMNPV, Rachiplusia ou NPV and Bombyx mori NPV), sharing nine defining genes.
