Impact of Simulated Insect Defoliation and Timing of Injury on Cabbage Yield in Minnesota [PDF]
In 1992 and 1994, field studies were done to assess the tolerance of transplanted cabbage to simulated insect defoliation and to determine if the defoliation level and growth stage at which defoliation begins influences final yield.

Simulated impacts of insect defoliation on forest carbon dynamics
Many temperate and boreal forests are subject to insect epidemics. In the eastern US, over 41 million meters squared of tree basal area are thought to be at risk of gypsy moth defoliation. However, the decadal-to-century scale implications of defoliation

Transcriptome differential expression analysis of defoliation of two different lemon varieties [PDF]
‘Allen Eureka’ is a bud variety of Eureka lemon with excellent fruiting traits. However, it suffers from severe winter defoliation that leads to a large loss of organic nutrients and seriously affects the tree’s growth and development as well as the ...

Damage Potential of Rose Chafer and Japanese Beetle (Coleoptera: Scarabaeidae) in Michigan Vineyards [PDF]
Responses of young non-fruiting grapevines, Vitis labrusca (L.) var. ‘Niagara’, to defoliation were examined at two stages of vine growth when beetles typically infest vineyards.

Effects of time and intensity of defoliation on yield and yield components of corn
In order to evaluate the effects of time (20, 40, 60 and 100 days after sowing) and intensity of defoliation (0, 33, 66 and 100%) on a corn cultivar ( three way cross 647), a complete randomized block design with split plot arrangement and three ...

Distribution of First Instar Gypsy Moths (Lepidoptera: Lymantriidae) Among Saplings of Four Tree Species Common in the Great Lakes Region [PDF]
We examined the inter-tree distribution of first instar gypsy moth larvae under natural dispersal conditions in the field in Michigan in 1991. The study focused on saplings of northern red oak (Quercus rubra), white oak (Q. alba), red maple (Acer rubrum),

Environmental Impact of Silicic Magmatism in Large Igneous Province Events
Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Effects of intensity and frequency of defoliation on a mixture of guinea grass (Panicum maximum cv. Coloniao) and Verano stylo (Stylosanthes hamata cv. Verano) : a thesis presented in partial fulfilment of the requirements for the degree of Master of Agricultural Science in Plant Science at Massey University [PDF]
A study was conducted in a glasshouse to determine the effect of defoliation treatments comprising combinations of two intensities (7.5 cm and 15.0 cm cutting height) and three frequencies (2, 3 and 6 weeks) on production, botanical composition and crude
