lar·va

 (lär′və)
n. pl. lar·vae (-vē) or lar·vas
1.
a. The newly hatched, wingless, often wormlike form of many insects, developing into a pupa in species that undergo complete metamorphosis.
b. The six-legged immature form of a tick or mite.
2. The newly hatched, earliest form of any of various animals that undergo metamorphosis, differing markedly in appearance from the adult.
3. Roman Mythology A malevolent spirit of the dead.

[Latin lārva, specter, mask (because it acts as a specter of or a mask for the adult form).]

lar′val adj.
Word History: The word larva referring to the newly hatched form of insects before they undergo metamorphosis comes from the Latin word lārva, meaning "evil spirit, ghost, demon." The Latin word also was used to mean "a terrifying mask," such as one that might have been worn by a Roman performer in the role of such an evil spirit. In the 1600s and 1700s, scientists began to use the Latin word to describe the stage in an insect's life during which its final form is still hidden—the larval stage is a mask, so to speak, that the insect will later remove to reveal its adult appearance.

lar·va

(lär′və)
Plural larvae (lär′vē) or larvas
1. An animal in an early stage of development that differs greatly in appearance from its adult stage. Larvae are adapted to a different environment and way of life than adults and go through a process of metamorphosis in changing to adults. Tadpoles are the larvae of frogs and toads.
2. The immature, wingless, and usually worm-like feeding form of those insects that undergo three stages of metamorphosis, such as butterflies, moths, and beetles. Insect larvae hatch from eggs, later turn into pupae, and finally turn into adults. Compare imago, nymph, pupa.

"From that, we speculated that since nitric oxide also controls the timing of life cycle changes in the stages of other simple organisms, it may have a long evolutionary history of controlling life cycle transitions," explains Brandhorst, "allowing organisms to regulate when they become sexually mature, which in many animals involves going through metamorphosis from the larval stage to a juvenile or adult stage."
It also worked better when insects were soft-bodied, during the larval stage. In fact, the pepper extracts were found to be as efficient as the synthetic pesticide diazinon, which is being phased out of use in Canada and will not be available for sale for domestic use after December 31, 2004.--NL--

"In the field you may have higher mortality rates because of the cumulative effect of being exposed to the toxin throughout the larval stage," said researcher Mr John Obrycki.
This difference in resting metabolic rate between adults and larvae at higher temperatures coupled with the "insensitivity" to temperature change exhibited by larvae between 0[degrees]C and 20[degrees]C indicates that possessing a larval stage of development may be beneficial to E.
A deterministic mathematical model was designed to: 1) predict the duration of the weakfish larval stage as afunction of prey density, 2) calculate the percent mortality incurred by weakfish larvae at any discrete prey density, and 3,) estimate critical rates of instantaneous mortality, rates at which a weakfish recruitment failure could occur.
Our specific objectives were fourfold: (1) to determine whether larger individuals at a given age (i.e., individuals larger-at-age) had a higher probability of survival (i.e., the "bigger-is-better" mechanism), (2) to determine whether faster growing individuals had a higher probability of survival (i.e., the "growth-rate" mechanism), (3) to determine whether individuals that had a shorter larval stage had a higher probability of survival (i.e., the "stage-duration" hypothesis), and (4) to calculate the correlations among larval size, growth rate, and development rate in order to assess the ability of the above three mechanisms to act independently.
