A note on the population genetic consequences of delayed larval development in insects
Genetics and Molecular Biology, 2013 Observations by Dobzhansky's group in the 1940s suggesting that the presence of recessive genotypes could account for lower larval developmental rates in Drosophila melanogaster were not confirmed at the time and all subsequent investigations on this ...

Larval Development: Making Ants into Soldiers [PDF]
Current Biology, 2019 Many ant species have complex caste systems, with reproductive queens and sterile workers, which often play distinct roles in the maintenance and defense of the colony. A new study sheds light on how these worker caste systems evolved and the mechanisms by which totipotent larvae give rise to the alternative adult castes.

Acta Biologica Slovenica, 2013 Exoskeletal cuticle of crustaceans is a chitinous matrix, produced apically by epidermis and stiffened by sclerotization and calcification. Embryos of terrestrial isopod crustacean Porcellio scaber develop within the female brood pouch, marsupium, and ...

Journal of Insect Science, 2004 In insects, the outcome of intraspecific competition for food during development depends primarily upon larval density and larval sex, but effects will also depend on the particular trait under consideration and the species under study.

Incorporation of Radioiodine into the Developing Endostyle of the Larval Lamprey. (developing endostyle/radioiodine-incorporation/larval lamprey) [PDF]
Development, Growth and Differentiation, 1982 Incorporation of radioiodine (131 I- ) into small larvae of the Japanese river lamprey, 14 days after fertilization, was studied by radioautography. A small amount of radioiodine was incorporated into the larvae and became located in the mid-dorsal region of endostylar cells.

LARVAL DEVELOPMENT OF PALAEMONETES PUGIO HOLTHUIS ,
The Biological Bulletin, 1957 1. Palaemonetes pugio Hobthuis and Palaemonetes vulgaris (Say) were reared in the laboratory from eggs through metamorphosis.2. The larvae of these species are very nearly identical except for a pair of chromatophores found on abdominal sternite 2 of P. pugio but lacking from P. vulgaris.
