  • The Influence of Induced Host Moisture Stress on the Growth and Development of Western Spruce Bud Worm and Armillaria Ostoyae on Grand Fir Seedlings
    AN ABSTRACT OF THE THESIS OF Catherine Gray Parks for the degree of Doctor of Philosophy in the Department of Forest Science, presented on April 28, 1993. Title: The Influence of Induced Host Moisture Stress on the Growth and Development of Western Spruce Budworm and Armillaria ostoyae on Grand Fir Seedlings. Abstract Approved: John D. Waistad This greenhouse study evaluates the influence of separately and simultaneously imposed water stress, western spruce budworm (Choristorneura occidentalis Freeman) defoliation, and inoculation with the root pathogen, Armillaria ostoyae (Romagn.) Herink, on the growth and biochemical features of Abies .grandis (Dougl.) Lindi. Seedling biomass, plant moisture status, bud phenology, and allocation patterns of phenolics, carbohydrates, and key nutrients (nitrogen, phosphorus, potassium and sulfur) are reported. Hypotheses are developed and testedon the impacts of water-stress, defoliation, and root inoculation, on westernspruce budworm growth and development, and Armillaria ostoyae-caused mortality and infection. Western spruce budworm larvae fedon water-stressed seedlings had higher survival rates, grew faster, and produced largerpupae than those fed on well- watered seedlings. There is no clear reason for the positive insectresponse, but changes in foliage nutrient patterns and phenolic chemistryare indicated. Insect caused defoliation has been earlier reported to enhance successful colonization of Armillaria spp. on deciduous trees in the forests of the northeastern United States. The positive response of the fungus was attributed to a weakened tree condition. Conversely, although this study conclusively found water-limited trees to have increased susceptibility to A. ostoyae, defoliation significantly lowered Armillaria-caused infection and mortality. The decline in infection success is attributed to defoliation-caused reduction in plant water stress and an alteration of root carbohydrate chemistry.

  • Post-Fire Recovery of Woody Plants in the New England Tableland Bioregion
    Post-fire recovery of woody plants in the New England Tableland Bioregion Peter J. ClarkeA, Kirsten J. E. Knox, Monica L. Campbell and Lachlan M. Copeland Botany, School of Environmental and Rural Sciences, University of New England, Armidale, NSW 2351, AUSTRALIA. ACorresponding author; email: [email protected] Abstract: The resprouting response of plant species to fire is a key life history trait that has profound effects on post-fire population dynamics and community composition. This study documents the post-fire response (resprouting and maturation times) of woody species in six contrasting formations in the New England Tableland Bioregion of eastern Australia. Rainforest had the highest proportion of resprouting woody taxa and rocky outcrops had the lowest. Surprisingly, no significant difference in the median maturation length was found among habitats, but the communities varied in the range of maturation times. Within these communities, seedlings of species killed by fire, mature faster than seedlings of species that resprout. The slowest maturing species were those that have canopy held seed banks and were killed by fire, and these were used as indicator species to examine fire immaturity risk. Finally, we examine whether current fire management immaturity thresholds appear to be appropriate for these communities and find they need to be amended. Cunninghamia (2009) 11(2): 221–239 Introduction Maturation times of new recruits for those plants killed by fire is also a critical biological variable in the context of fire Fire is a pervasive ecological factor that influences the regimes because this time sets the lower limit for fire intervals evolution, distribution and abundance of woody plants that can cause local population decline or extirpation (Keith (Whelan 1995; Bond & van Wilgen 1996; Bradstock et al.

In the present study, a Y-tube olfactometer was employed to investigate whether the parasitoid T. radiata is capable of utilizing the odour source emitted by both plants and insect hosts during its foraging. The odour sources included Murraya paniculata (L.) shoots, 1st, 2nd, 3rd, 4th, and 5th D. citri instar nymphs, both individually and in combinations. Moreover, nymph-stage choice for parasitism, including 3rd, 4th, and 5th D. citri instar nymphs, was carried out. The results indicated that female T. radiata were only significantly attracted to volatiles emitted by M.
