ISOLATION OF THE DITERPENOIDS, ENT-KAURAN-16α-OL AND ENT-ATISAN-16α-OL, FROM SUNFLOWERS, AS OVIPOSITION STIMULANTS FOR THE BANDED SUNFLOWER MOTH, Cochylis hospes
TLDR
Two diterpenoid alcohols were isolated from pre bloom (R3-R4 stage) sunflower heads as oviposition stimulants for the banded sunflower moth, Cochylis hospes and showed that 1 was relatively more stimulatory than 2, and that there was no synergistic effect on Oviposition when the two compounds were combined.
Integrated Pest Management of Sunflower Insect Pests in the Northern Great Plains
TLDR
Plant architecture, growth phenology and plant community were altered when sunflowers were changed from wild to cultivated and a number of insects made the transition from the wild plant type to the cultivated plant to feed and develop.
Sunflowers: Their History and Associated Insect Community in the Northern Great Plains
The sunflower, Heliantbus annuus var. macrocarpus (DC.) Ckll., is the only row crop in the northern Great Plains that coexists with its native congeners, Because of this unique ecological situation,
Effects of planting date on damage caused by the banded sunflower moth (Lepidoptera: Cochylidae) in the northern great plains
TLDR
Planting sunflowers late in southeastern North Dakota and northwestern Minnesota can reduce moth damage without appreciably reducing achene weight and oil content.
Bionomics and seasonal abundance of the banded sunflower moth (Lepidoptera: Cochylidae) on cultivated sunflower in the northern Great Plains
TLDR
Seasonal patterns of the life stages of banded sunflower moth were similar, but population densities varied among years, and linear regression analysis of measurements of head capsule width and body length substantiated that the larvae develop through five instars.
Domestic Acarina of Colombia: occurrence and distribution of Acari in house dust.
TLDR
The distribution and occurrence of mites collected from house dust in various climatic and altitudinal zones of Colombia were investigated and certain species of which have been shown to be producers of allergens were shown.
Insecticidal Control of Banded Sunflower Moth, Cochylis hospes (Lepidoptera: Cochylidae), Larvae at Different Sunflower Growth Stages and Dates of Planting in North Dakota
In 1983, both chlorpyrifos and fenvalerate applied at three different plant growth stages were effective in preventing sunflower yield loss caused by larval feeding of the banded sunflower moth
Distribution and Abundance of a Stem Weevil, Cylindrocopturus adspersus (Coleoptera: Curculionidae), in Cultivated Sunflower in the Northern Plains
TLDR
Overwintering sites were in the upper root crown and in the base of the plant stalk, with half the larvae between soil level and 4 cm above soil level, with no correlation between stalk diameter and number of larvae per stalk.
Seasonal abundance and parasitism of the sunflower beetle (Coleoptera: Chrysomelidae) on cultivated sunflower in the Northern Great Plains
TLDR
Postdiapause adults of the sunflower beetle, Zygogramma exclamationis (F), appeared in plots of sunflower, Helianthus annuus L., between 28 May and 9 June and were present until mid-July 1985-1987, although population densities varied, life history patterns were similar among the 3 yr.
