Residual effectiveness of plaster matrix formulations of temephos and temephos plus an emulsifier (Atlox 3409F) were evaluated against Aedes aegypti larvae during an 8-wk period. Formulations of 2% and 5% (AI) Atlox with 5% (AI) temephos yielded 100% larval mortality for 8 wk. A 5% temephos formulation without the addition of the emulsifier produced 100% larval mortality through only 1 wk.

The Role of Larval Fat Cells in Starvation Resistance and Reproduction in Adult Drosophila melanogaster by Jerell Roland Aguila Dr. Deborah K. Hoshizaki, Examination Committee Chair Associate Professor of Life Sciences University of Nevada, Las Vegas The intricate life cycle of holometabolous insects includes well-defined larval and adult stages associated with feeding and non-feeding periods. ...

A vast body of work exists on the endocrine regulation of frog metamorphosis ( Dodd and Dodd 1976 , Shi 1999 , Denver et al. 2002 , Buchholz et al. 2006 , Furlow and Neff 2006 , Brown and Cai 2007 ), and a separate set of literature describes the dramatic larval period diversity found among amphibians ( Duellman and Trueb 1994 , McDiarmid and Altig 1999 ). This chapter begins to unite these top...

Genetic variation within plants and herbivores influence the biological attributes insect-plant interactions. We studied performance of different agro-ecological Chilo partellus (Swinhoe) populations on diverse maize genotypes during 2016-17 at ICAR-Indian Agricultural Research Institute, New Delhi. There was significant in larval period, survival, pupal weight, adult emergence C. test genotype...

Marine seafloor ecosystems, and efforts to restore them, depend critically on the influx and settlement of larvae following their pelagic dispersal period. Larval dispersal and settlement patterns are driven by a combination of physical oceanography and behavioral responses of larvae to a suite of sensory cues both in the water column and at settlement sites. There is growing evidence that the ...

We address the hypothesis that fish that grow rapldly as larvae also grow rapidly as juveniles. Winter flounder Pleuronectes amerlcanus were reared from hatching through the larval period and up to 2 mo into the juvenile period. Successive cohorts of fish which metamorphosed on the same day were pooled and measured at weekly intervals during the early juvenile period. Growth rates of larvae and...

Vegetation management for constructed treatment wetlands often involves knocking down emergent vegetation with heavy equipment and inundating the dead vegetation after a period of drying. Such practices create favorable conditions for larval mosquitoes. We studied the relationship between length of the drying period for an emergent macrophyte, Typha sp., and the abundance of aquatic invertebrat...

Studies were made on the duration of the prehatch period of Boophilus decoloratus and on the subsequent survival and viability of larvae under natural conditions. The length of the prehatch and larval survival periods was found to be inversely dependent on increased temperature. A high initial temperature at the time of female drop decreased the prehatch period further, resulting in synchronous...
