Hill reaction and frost hardening in cabbage
"The Problem. How often have men stopped and wondered at seeing plants surviving and struggling against temperature extremes which to all appearances have killed and destroyed other plants next to them? What inherent or developed ability is this that allows some to survive even when ice crystals …

Effects of low intensity magnetic fields on cabbage loopers
… fields on insects were studied using the cabbage looper moth, Trichoplusia ni (Hubner). In the first tests, adult loopers were used to determine their locational preference in response to areas of stronger or weaker magnetic field ranging from slightly above the geomagnetic field strength …

The cabbage whitefly, aleyrodes Proletella: causes of outbreaks and potential solutions
The cabbage whitefly, Aleyrodes proletella, has in recent years become a primary pest of several brassica crops in Europe. In the UK, its greatest impact has been on kale, where nymphs, wax deposits and sooty mould caused by honeydew excretion reduce the marketable portion of the crop, particularly …

Effect of electrostatic fields on insects: the housefly and cabbage looper
… fields on insects were studied using cabbage loopers, Trichoplusia ni (Hubner) and houseflies, Musca domestica L. Two series of tests were conducted; one to determine the electrostatic field effect on the locational preference and the other to determine the field effect on wingbeat. …

Cheeseweed (Malva Parviflora L.) Competition with Cabbage and Lettuce on Maui, Hawaii
In four field experiments transplanted cabbage was grown with cheeseweed sown at transplanting at densities from 0 to 70 weeds per 0.1 m2. Cheeseweed emerged in 3 to 7 days and overgrew the cabbage in 42 to 49 days. At harvest cabbages were trimmed to two wrapper leaves and weighed. Final weed …

Isis, Cabbage and Viper : new tools and strategies for designing responsive media
Responsive media are media that can sense and react intelligently to factors like presentation conditions or equipment, audience identity or profile, direct interaction, history or anticipation of involvement, and so on. The emergence of modern computational devices and communication networks, with …

Ocelli and octopamine and their effects on cabbage looper moth flight activity
… regulating the onset, intensity, and duration of cabbage looper moth flight activity were examined. This was achieved by studying the flight activity of control, sham, and anocellate moths with and without octopamine treatment. Sham and anocellate moths were produced by cauterization in …

Behavior of wild-type and laboratory-adapted cabbage loopers, Tr̲ich̲o̲pl̲u̲s̲i̲a n̲i (Hübner) (Lepidoptera:Noctuidae)
Three criteria, development, flight, and oviposition, were used to compare a laboratory-adapted and wild-type colony of Trichoolusia ni. The laboratory-adapted colony was further examined to determine the effect of larval crowding and starvation on the above criteria. The laboratory-adapted colony …

Broccoli yield response to cabbage looper and varietal preferences of lepidopterous pests of broccoli
… a nine-day mean of 8.4 and a 15-day mean of 12.1 cabbage looper larvae/plant did not significantly reduce yield in the Spring and Fall respectively. However, means of 7.4 and 11.1 cabbage looper larvae/plant reduced yield (head weight) under drought conditions. Harvest date was not affected by the …

Influence of living and non-living habitat complexity on arthropods in strip-tilled cabbage fields
… both forms of complexity were manipulated in cabbage fields. In 2010 and 2011, a field experiment was conducted examining the effects of herbicide intensity and oat kill date on arthropods, weeds, and crop yield. Reduced herbicide intensity was associated with 1) lower abundance of several key …
