A Technique For Estimating The Number Of Shoots On Pole-Sized Red Pine: The Relationship Of Selected Tree Parameters To Number Of Shoots In Central Wisconsin Sand Plains Plantations, J. H. Hainze, D. M. Benjamin Jul 2025

A Technique For Estimating The Number Of Shoots On Pole-Sized Red Pine: The Relationship Of Selected Tree Parameters To Number Of Shoots In Central Wisconsin Sand Plains Plantations, J. H. Hainze, D. M. Benjamin

The Great Lakes Entomologist

Diameter at breast height (dbh) , of ten tree parameters tested, was most highly correlated with the number of shoots per tree in six red pine plantations in the central Wisconsin sand plains. Tree height, frequently used as an estimator of shoot number in young conifers, was not highly correlated with shoot number. A strong, nonlinear correlation existed between branch diameter and number of shoots per branch. Multiple regressions using several tree parameters yielded the highest R2 values, however, dbh was judged the simplest and most practical estimator of shoot number for central Wisconsin red pine plantations.

Effect Of Artificial Defoliation On Broccoli Yield, W. S. Cranshaw, R. J. Default Jul 2025

Effect Of Artificial Defoliation On Broccoli Yield, W. S. Cranshaw, R. J. Default

The Great Lakes Entomologist

Broccoli plants were artificially defoliated at varying plant growth stages and defoliation intensities to determine bases for control decisions with lepidopterous defoliators. Low levels of defoliation (<25%) did not significantly depress head weight at any treatment date. Higher levels of defoliation severity (50%) depressed head weight when inflicted following the development of small (<2 cm) heads. Only complete defoliation (100%) consistently affected head weights. Because of the great ability of broccoli plants to compensate for leaf loss, most pre heading insecticide applications should be able to be eliminated in Minnesota without yield losses.

Winter Wheat Cold Hardiness And Fructan Reserves Affected By Rhopalosiphum Padi (Homoptera: Aphididae) Feeding, S. G. Wellso, C. R. Olien, R. P. Hoxie Jul 2025

Winter Wheat Cold Hardiness And Fructan Reserves Affected By Rhopalosiphum Padi (Homoptera: Aphididae) Feeding, S. G. Wellso, C. R. Olien, R. P. Hoxie

The Great Lakes Entomologist

The cold hardiness of 'Winoka' and 'Genesee' winter wheats was each significantly less (P = 0.05) when fed upon by bird-cherry oat aphids, Rhopalosiphum padi, than non-infested seedlings. Aphid feeding also reduced the amount of fructans in crown tissue ca. 20% compared to extracts from crowns of non-infested seedlings. It appears that the cold hardiness of these wheat cultivars may have been reduced because of fructan depletion by insect feeding.

Control Of Hyadaphis Tataricae (Homoptera: Aphididae) On Honeysuckle Including Observations On Host Plant Resistance, Philip L. Nixon, Carolyn Peet Nixon, James E. Schuster Jul 2025

Control Of Hyadaphis Tataricae (Homoptera: Aphididae) On Honeysuckle Including Observations On Host Plant Resistance, Philip L. Nixon, Carolyn Peet Nixon, James E. Schuster

The Great Lakes Entomologist

llyadaphis tataricae causes witches-brooming to the growing tips of Zabelii and other large bush-type honeysuckles in the north central states. Insecticide tests show that acephate (Orthene), dimethoate (Cygan), or oxydemeton-methyl (Metasystox-R) sprayed monthly in June and July will reduce witches-brooming. Malathion was not effective in reducing damage. Host plant resistance observations indicate that Lonicera x notha, L. x muendeniensis, L. x amoena 'Alba', L. x ).;ylosteoides, and L. tatarica 'Arnold Red' are ll. tataricae resistant. These large bush-type honeysuckles would appear to be good replacements for Zabelii and other susceptible honeysuckles in ornamental plantings.

Interspecific Interactions Between Orchelimum Nigripes And Orchelimum Volantum (Orthoptera: Tettigoniidae), Marianne Niedzlek Feaver Jul 2025

Interspecific Interactions Between Orchelimum Nigripes And Orchelimum Volantum (Orthoptera: Tettigoniidae), Marianne Niedzlek Feaver

The Great Lakes Entomologist

[Excerpt] Interspecific interactions are relatively rare among coinhabiting Orthoptera. Most records are of overzealous males courting females not of their species or, for that matter, inanimate objects. Less frequent are reports of two signalling males interacting, yet these are of interest. Calling songs are used to distinguish species (Alexander 1956). The possibility then exists that the "interference" or, more correctly, the competition for broadcast space that occurs when two closely related species with similar songs interact, may have been influential in shaping aspects of song delivery or pattern.
