Transmission of Impatiens Necrotic Spot Virus in Peppermint by Western Flower Thrips (Thysanoptera: Thripidae)
- J. DeAngelis, D. Sether, P. Rossignol
- Biology
- 1 February 1994
Western flower thrips, Frankliniella occidentalis (Pergande), can transmit a begonia isolate of impatiens necrotic spot virus (INSV) to peppermint, Mentha piperita L. ‘Black Mitcham’, and virus was detected throughout the plant indicating a systemic infection.
Influence of tree age and growth rate on the radial resin duct system in loblolly pine (Pinus taeda)

- 1 May 1986
Radial duct formation was found to be positively correlated with radial growth rate, when growth rate is expressed as increment of cross-sectional area growth, which may partially explain why older, slower growing trees tend to be more susceptible to attack by the southern pine beetle.
Survival, Development, and Reproduction in Western Flower Thrips (Thysanoptera: Thripidae) Exposed to Impatiens Necrotic Spot Virus

- 1 December 1993
Western flower thrips exposed through feeding as larvae to the impatiens necrotic spot virus (INSV) had lowered survival and reproductive potential and slower development rate than did unexposed thrips under controlled environmental conditions.
Photosynthesis, Leaf Conductance, and Leaf Chlorophyll Content in Spider Mite (Acari: Tetranychidae)-Injured Peppermint Leaves
- J. DeAngelis, R. Berry, G. W. Krantz
- Biology
- 1 April 1983
Effects of feeding injury by the twospotted spider mite on 14-CO2 assimilation, leaf conductance to gas exchange, and leaf chlorophyll in peppermint, Mentha piperita L., were investigated.
Evidence for Spider Mite (Acari: Tetranychidae) Injury-Induced Leaf Water Deficits and Osmotic Adjustment in Peppermint
- J. DeAngelis, R. Berry, G. W. Krantz
- Biology
- 1 April 1983
Accumulation of soluble leaf carbohydrate in water-stressed leaves may help mite-injured leaves maintain cell turgor pressure through an osmotic adjustment (osmoregulation) mechanism.
Effects of Spider Mite (Acari: Tetranychidae) Injury on Essential Oil Metabolism in Peppermint
- J. DeAngelis, A. Marin, R. Berry, G. W. Krantz
- Biology
- 1 April 1983
Increased supply of carbohydrate from surrounding water-stressed mesophyll cells may provide the additional energy needed for the acceleration of pulegone reduction to menthol isomers in mite-injured peppermint leaves.
