Delayed local responses of downy birch to damage by leafminers and leafrollers

Oikos, 2011
Recent findings suggest that impacts of endemic herbivory on forest ecosystems over the long term may exceed impacts of herbivore outbreaks. However, responses of trees to minor and local damage imposed by small arthropod herbivores, especially by those mining or skeletonising individual leaves, remain poorly understood.

Mixed Planting of Potato Cultivars: Growth, Yield and Leafminer Damage in the Cool Tropics

Experimental Agriculture, 1991
SummaryThe influence of planting mixtures of two potato cultivars on the incidence of leafminer fly (Liriomyza huidobrensis (Blanchard)) and on damage to potato foliage, and the effect on growth and yield, was studied in two field experiments in coastal Peru.

Evaluation of Trapping and Trap Types to Reduce Damage to Potatoes by the Leafminer, Liriomyza Huidobrensis (Diptera, Agromyzidae)

International Journal of Tropical Insect Science, 1987
Four types of trap, yellow water, yellow sticky board, bottle with 20% protein hydrolysate, and funnel with 10% casein hydrolysate, were field-tested to control Liriomyza huidobrensis (Blanchard) in the coastal region of Peru. The yellow sticky boards were the most effective in trap capture with a mean of 1193.92 L. huidobrensis per week.

Association of citrus leafminer Phyllocnistis citrella (Lepidoptera: Gracillariidae) damage with physiological parameters and larval weight in Citrus reticulata

International Journal of Tropical Insect Science, 2017
AbstractThe citrus leafminer (CLM),Phyllocnistis citrellaStainton causes injury to citrus and related species in the Rutaceae family. The damage that the CLM larvae can cause is significant in citrus plantations. We tested two citrus cultivars — ‘Kinnow’ (Citrus reticulataBlanco) and ‘Fairchild’ (a hybrid ofCitrus reticulataClementine x Orlando Tangelo)

Accelerated Abscission of Cranberry Leaves Damaged by the Leafminer, Coptodisca negligens (Lepidoptera: Heliozelidae)

Environmental Entomology, 1989
The effect of damage by the heliozelid leafminer, Coptodisca negligens Braun, on abscission of cranberry, Vaccinium macrocarpon Aiton, leaves was studied in Connecticut during 1986. The abscission of second-year leaves was significantly greater and earlier on wild and potted vines with leafminer injury than on those without injury.

EVALUATION OF NON-INSECTICIDAL METHODS TO REDUCE DAMAGE TO CHRYSANTHEMUMS BY THE LEAFMINER LIRIOMYZA TRIFOLII (DIPTERA: AGROMYZIDAE)

The Canadian Entomologist, 1984
AbstractThree biological control methods were evaluated for the reduction of damage to chrysanthemums by the leafminer Liriomyza trifolii (Burgess). Yellow sticky boards trapped adults and reduced the damage by 50%, Afugan 30 EC effectively controlled the damage to chrysanthemums, and interplanting with field beans as a trap crop showed potential for ...

Visual, semi‐quantitative assessments allow accurate estimates of leafminer population densities: an example comparing image processing and visual evaluation of damage by the horse chestnut leafminer Cameraria ohridella (Lep., Gracillariidae)

Journal of Applied Entomology, 2003
Abstract: Qualitative or semi‐quantitative visual assessments are most often used for estimating population size of herbivorous insects. The precision of these estimates, however, is often difficult to establish. A ‘simulation game’ with the horse chestnut leafminer, Cameraria ohridella Deschka & Dimic (Lep., Gracillariidae) shows that visual, semi‐

Contrasting response of mountain birch to damage by Eriocrania leafminers in polluted and unpolluted habitats

Canadian Journal of Botany, 2005
The leafmining larvae of Eriocrania spp. (Lepidoptera, Eriocraniidae) develop in the expanding leaves of mountain birch, Betula pubescens subsp. czerepanovii (Orlova) Hämet-Ahti. The larva usually consumes over a half of the leaf, implying moderate foliar damage to an individual shoot.

Effect of Chlorpyrifos+BPMC Insecticide Spray on the Population Density, Damage and Natural Enemies of Leafminer [Liriomyza trifolii (Burgess)] on Onion (allium cepa Linn.) Grown After Rice (Oryza sativa Linn.)

The Philippine Entomologist Volume 23, 2009
A 2-year study was conducted on the population density of adults, larvae, extent of damage, and larval parasitoids of the onion leafminer (LM) Liriomyza trifolii (Burgess) in weekly-sprayed and unsprayed onion fields in Bongabon, Nueva Ecija, Philippines. The area is known for large-scale cultivation of onion during the dry months from December to May.
