Adult feeding increases fecundity in female Helicoverpa armigera (Lepidoptera: Noctuidae)
|
Key words. Noctuidae, Helicoverpa armigera, adult feeding, fecundity, lifespan
Abstract. The availability and quality of nectar for adults are thought to affect fecundity of the cotton bollworm, Helicoverpa armigera (Hübner) (Lepidoptera: Noctuidae). Experiments were conducted to analyze the effect of adult feeding on the fecundity, and oviposition pattern of moths, and larval performance (egg hatch). The moths were fed either on distilled water, honey solution, or one of a range of c...

Dynamics of reproductive allocation from juvenile and adult feeding: radiotracer studies.
Ecology
; INTRODUCTION An organism's reproduction is fueled by nutrients that may be gathered during both its juvenile and adult stages. Nutrients spent on reproduction but derived from juvenile feeding must be stored until adulthood. These nutrients are capital reserves (in terms like those of Sibly and

Variation in size and composition of Bufflehead (Bucephala albeola) and Barrow's Goldeneye (Bucephala islandica) eggs.
The Wilson Journal of Ornithology
; For many bird species, nutrient content is positively correlated with egg size. Consequently, egg size is often used as an indicator of egg and hatchling quality (Birkhead 1984, Sotherland and Rahn 1987, Pelayo and Clark 2002). There are many potential benefits to laying larger, and presumably

A metamorphic inducer in the opisthobranch Haminaea callidegenita: partial purification and biological activity.
The Biological Bulletin
; Introduction Larvae of most benthic marine invertebrate species are induced to metamorphose by a cue, either chemical or physical, that identifies a specific habitat as suitable for juvenile or adult existence (reviewed by Pawlik, 1992). This cue, or metamorphic inducer, triggers a radical

Christmas Shearwater Egg Dimensions and Shell Characteristics on Laysan Island, Northwestern Hawaiian Islands.(Statistical Data Included)
Wilson Bulletin
; The Christmas Shearwater (Puffinus nativitatis) is a tropical procellariiform seabird that breeds on islands in the central North and South Pacific oceans (Warham 1990). It has been little studied, perhaps because the species is not abundant anywhere (Shallenberger 1984). The purpose of the present

Egg-mass gel of Melanochlamys diomedea (Bergh) protects embryos from low salinity. (opisthobranch gastropod)
The Biological Bulletin
; Introduction Many marine invertebrates embed their embryos in gelatinous masses. Because gel eliminates convective transport within masses, it slows the exchange of material between embryos and seawater. Reduced exchange may adversely affect embryos. For example, embryos in the centers of globose
