Comparative embryology of Nomia melanderi, Megachile rotundata, and Bombus griseocollis (Hymenoptera:Apoidea)

Creator:: Hartman, Margaret Jane
Abstract:: Organogenesis was observed in different age embryos and first instar larvae of Nomia melanderi Cockerell (Halictidae), Megachile rotundata (Fabricius) (Megachilidae), and Bombus griseocollis (DeGeer) (Apidae) (Hymenoptera : Apoidea). It was found that, with the exception of the ventral nerve cord, comparable organ development had occurred by the beginning of the...

Phospholipids of Tenebrio molitor larvae

Creator:: Kamienski, Francis Xavier
Abstract:: Phospholipids of Tenebrio molitor larvae were separated on columns of DEAE-cellulose and silicic acid-Hyflo Super Cel. The major phosphatide components were identified by various analytical procedures. Phosphatidyl choline was demonstrated to be the predominant phospholipid with a high percentage of phosphatidyl ethanolamine. A small amount of inositol-containing phosphatides were present....

Essential fatty acids in noctuid moths : their nutrition and metabolism

Creator:: Grau, Philip Alvin, 1941-
Abstract:: The polyunsaturated fatty acids (PUFA) are known to be required for larval growth and normal wing development in several species of Lepidoptera but most of the basic information necessary for a complete understanding of this nutritional phenomenon has not been gathered. This includes the role of each of the essential...

Regional population dynamics of Argyrotaenia citrana in Northwest caneberry : phenology, overwintering survivorship, and movement as measured by pheromone traps and larval sampling

Creator:: Knight, Alan Lee
Abstract:: Developmental requirements were determined for both larva and pupa as 503 and 176 degree-days (dd) above a lower threshold of 5°C. Adult emergence occurred from 300 to 700 dd accumulated from January 1st. Cumulative male emergence preceded female's by 50 - 80 dd. A PETE phenology model modified to include...

Taxonomy and evolution of the Orthotyline genus Lopidea (Heteroptera: miridae)

Creator:: Asquith, Adam
Abstract:: The genus Lopidea Uhler is revised for America north of Mexico. The relationship of Lopidea to other orthotyline genera is discussed and it is proposed that the genus Ilnacora Reuter is the sister group of Lopidea. Forty-eight species of Lopidea are recognized in North America, one of which is described...
