Toxicology Of Chemical Stress To Monarch Butterflies (Danaus Plexippus L.), Annie Krueger Aug 2021

Toxicology Of Chemical Stress To Monarch Butterflies (Danaus Plexippus L.), Annie Krueger

Department of Entomology: Dissertations, Theses, and Student Research

Monarch butterfly (Danaus plexippus L.) population declines have caught the attention of the country and prompted nationwide conservation initiatives. The United States Fish and Wildlife Service has identified insecticide exposure and loss of milkweed (Asclepias spp.) reproductive habitat as primary threats to the monarch. In the Midwestern US, milkweed largely occurs around cropland borders where there may be a spatial and temporal overlap of monarch larvae, insecticide usage, and fertilizer applications. In this study, the acute toxicity and sub-lethal effects on growth and diet consumption of two commonly used pyrethroid insecticides, bifenthrin and beta-cyfluthrin, were characterized …


Northern Fulmars (Fulmarus Glacialis) As Bio-Indicators Of Endocrine Disrupting Plasticizers In The Marine Surface Environment., Olivia Feinstein Jan 2012

Northern Fulmars (Fulmarus Glacialis) As Bio-Indicators Of Endocrine Disrupting Plasticizers In The Marine Surface Environment., Olivia Feinstein

Summer Research

The plastics that make up over 10% of human waste are synthesized with phthalate plasticizers which are utilized in plastics as an additive to improve durability and flexibility. Many phthalates have been identified as endocrine disrupting chemicals (EDCs) and studies have shown dramatic deleterious effects as a result of species exposure to growing numbers of EDCs in the environment. Northern Fulmars (Fulmarus glacialis) are a northern hemisphere seabird species that forages opportunistically, meaning that they take advantage of a wide variety of different food sources, including inadvertent consumption of plastic. In addition to occupying space in the individuals’ …
