Geographic Variation In Blue Orchard Bee (Osmia Lignaria) Development And Performance As A Managed Pollinator In The Western United States, Morgan B. Scalici
All Graduate Theses and Dissertations, Fall 2023 to Present
Most flowering plants, including many cultivated food crops, will only produce well-developed fruits and seeds if pollen is transferred from one flower to another with the help of an animal pollinator. Honey bees are the most well-known and ubiquitous but are poor pollinators of some commercially important crops, or are in poor supply during crop bloom. In such cases, farmers will employ other managed pollinators such as bumble bees or solitary bees like mason and leafcutting bees. The blue orchard bee is North America's most agriculturally important native mason bee as effective pollinators of spring-blooming fruit crops. Differences in developmental …
Ecological Management Of The Alfalfa Leafcutter Bee, Megachile Pacifica (Panzer), With Emphasis On Diapause Induction, Ron M. Bitner
Ecological Management Of The Alfalfa Leafcutter Bee, Megachile Pacifica (Panzer), With Emphasis On Diapause Induction, Ron M. Bitner
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
The effects of photoperiod and temperature on diapause induction in the alfalfa leafcutter bee, Megachile pacifica (Panzer) (=M. rotundata Auct.), were studied during the summers of 1972, 1973 and 1974, The influence of photoperiod and temperature on mortality, rate of development and incidence of diapause was measured during the developmental stages of this insect. The aim of this research was to assess the potential for manipulation of the number of generations of this bee per season so as to develop a practical and ecologically-sound method of management,
Eggs, larvae, pupae and adults of M. pacifica were subjected to regimens …
