Abstract:
In this study, four inhibitor of apoptosis genes (iaps) in the genome of Epiphyas postvittana nucleopolyhedrovirus (EppoMNPV) that are homologous to iap-1, iap-2, iap-3 and iap-4 genes of other baculoviruses have been identified. All four iap genes were sequenced and the iap-1 and iap-2 genes were shown to be functional inhibitors of apoptosis. The iap-1, iap-2 and iap-3 genes contain two baculovirus apoptosis inhibitor repeat motifs and a C3HC4 RING finger-like motif. The activity of the iap genes was tested by transient expression in Spodoptera frugiperda (Sf-21) cells treated with the apoptosis-inducing agents actinomycin D, cycloheximide, anisomycin, tumour necrosis factor-α and UV light. The iap-2 gene prevented apoptosis induced by all agents tested, indicating activity towards a conserved component(s) of multiple apoptotic pathways. However, the iap-2 gene was unable to function in the absence of a gene immediately upstream of iap-2 that has homology to the orf69 gene of Autographa californica MNPV. The use of a CMV promoter rescued the apoptosis inhibition activity of the iap-2 gene, indicating that the upstream orf69 homologue is associated with expression of iap-2. The iap-1 gene was able to delay the onset of apoptosis caused by all of the induction agents tested but, unlike iap-2, was unable to prevent the development of an apoptotic response upon prolonged exposure of cells to the apoptosis induction agents. No anti-apoptotic activity was observed for the iap-3 and iap-4 genes of EppoMNPV.

Abstract:
Codling moth (Cydia pomonella) and leafrollers principally lightbrown apple moth (Epiphyas postvittana) are key pests of apples Pheromone mating disruption has until now required separate dispensers to be deployed for each pest group With 6001000 dispensers per ha for each species application costs are a significant factor limiting the wider adoption of multispecies mating disruption in New Zealand apple orchards The aim was to integrate the two disruption systems into a single dispenser and evaluate its performance against that of separate dispensers in paired block comparisons on four apple orchards The three measures of effectiveness pheromone trap catch suppression of moth mating and fruit damage at harvest all showed no statistical differences between the two treatments The performance of the new combination pheromone dispenser was equivalent to that when the two dispensers were deployed separately

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 gum leaf skeletoniser (Uraba lugens) a significant pest in Australia is now well established on Eucalyptus spp in the Auckland region One larval parasitoid (Meteorus pulchricornis) and two pupal parasitoids (Xanthopimpla rhopaloceros and Anacis sp) were recorded from U lugens collected in southwest Auckland Parasitism of M pulchricornis and X rhopaloceros against U lugens and other hosts in New Zealand (Helicoverpa armigera and Epiphyas postvittana respectively) was compared using nochoice and choice tests under controlled conditions Uraba lugens is a suitable host for development of both M pulchricornis and X rhopaloceros Choice tests revealed that M pulchricornis prefers H armigera larvae to U lugens Attack by X rhopaloceros occurred only when host pupae were presented within their cocoons Meteorus pulchricornis may compete with proposed classical biological control agents introduced against U lugens while X rhopaloceros is more likely to complement them

Abstract:
AbstractTwo generalist parasitoids,Dolichogenidea tasmanica(Cameron) (Hymenoptera: Braconidae) andTherophilus unimaculatus(Turner) (Hymenoptera: Braconidae) attack early instars of tortricid moths, including the light brown apple moth,Epiphyas postvittana(Walker) (Lepidoptera: Tortricidae). The two parasitoids co-exist in natural habitats, whileD. tasmanicais dominant in vineyards, whereasT. unimaculatusoccurs mainly in adjacent native vegetation. This difference suggests possible competition between the two species, mediated by habitat. Here, we report on the extent of interspecific differences in host discrimination and the outcome of interspecific competition between the two parasitoids. The parasitoids did not show different behavioural responses to un-parasitized hosts or those that were parasitized by the other species. Larvae ofD. tasmanicaout-competed those ofT. unimaculatus, irrespective of the order or interval between attacks by the two species. The host larvae that were attacked by two parasitoids died more frequently before a parasitoid completed its larval development than those that were attacked by a single parasitoid. Dissection of host larvae parasitized by both species indicated that first instars ofD. tasmanicaattacked and killed larvalT. unimaculatus.

Abstract:
Epiphyas postvittana (Walker, 1863) is an invasive polyphagous pest for the Azores and its bioecology and the potential natural enemies were unknown. We evaluated the temporal profile of this species larval abundance and the number of males captured in sex pheromone traps, hypothesizing that both profiles were similar. The study was carried out on seven endemic host plants and one native species grown in two forest nurseries (Furnas and Nordeste) in São Miguel Island over two years from 2018 to 2019. A total of 827 plants attacked by E. postvittana were observed in Furnas nursery (2018: 503, 2019: 324) and 1227 in the Nordeste (2018: 649, 2019: 578), including the presence of 525 larvae distributed by the Furnas (2018: 178, 2019: 79) and from the Nordeste (2018: 131, 2019: 137). In 2019, the average weekly number of males captured in the sex pheromone traps (total 31 weeks) were higher in Furnas (mean ± SE: 9.68 ± 1.982) than in Nordeste (3.33 ± 0.651). In synthesis, (i) the population density varied throughout the year and as a function of the host plant species in production; (ii) the abundance profile of larval and adults suggests has at least three to four generations per year and that adults are active year-round, experiencing some delayed development during the winter; (iii) a low larval density does not represent very serious damage to Azorean endemic plants, but is reflected in the population density of its natural enemies; (iv) some biological control agents are present in the field, parasitizing the larvae (i.e., Braconidae species of Meteorus ictericus (Nees, 1811) and Microgaster opheltes Nixon, 1968); (v) finally, the knowledge of the population dynamics and its natural enemies needs further and long-term study.
