The implications of temperature-mediated plasticity in larval instar number for development within a marine invertebrate, the shrimp Palaemonetes varians. [PDF]
PLoS ONE, 2013 Variations in larval instar number are common among arthropods. Here, we assess the implications of temperature-mediated variations in larval instar number for larval development time, larval growth rates, and juvenile dry weight within the palaemonid ...

Aedes aegypti pharate 1st instar quiescence affects larval fitness and metal tolerance [PDF]
Journal of Insect Physiology, 2012 The eggs of the mosquito Aedes aegypti possess the ability to undergo an extended quiescence hosting a fully developed 1st instar larvae within the chorion. As a result of this life history trait pharate larvae can withstand months of quiescence inside the egg where they depend on stored maternal reserves. A.

Acta Scientiarum: Biological Sciences, 2020 The natural parasitic behavior of parasitoids should be known by those in charge of planning strategies for the biological control of pests; therefore, the aim of the present study was to determine the larval instar of Anticarsia gemmatalis Hübner ...

Description of larval instars of Mystrophorus formicaeformis Ruthe (Hymenoptera: Dryinidae) [PDF]
Zootaxa, 2010 The last immature stage and the mature larva of Mystrophorus formicaeformis Ruthe are described for the first time. The affinities of both immature and mature larvae of M. formicaeformis and corresponding instars of other subfamilies are respectively discussed.

Studies on Resistance to Vegetative (Vip3A) and Crystal (Cry1A) Insecticidal Toxins of Bacillus thuringiensis in Heliothis virescens (Fabricius) [PDF]
, 2009 Bacillus thuringiensis (Bt) toxins expressed in commercial transgenic crop varieties are all δ-endotoxins (Cry toxins) but the identification of novel vegetative insecticidal proteins (Vip toxins) has extended the range of insecticidal proteins derived

Cumulative effect of HaNPV against Helicoverpa armigera infesting Chickpea
Environment Conservation Journal, 2016 The instar-wise larval mortality in H. armigera due to HaNPV @ 0.500 ml/l showed a consistent decrease in all the five instars and cent per cent larval mortality was recorded in the first instar larvae.

BMC Biology, 2021 Background The detection of environmental cues and signals via the sensory system directs behavioral choices in diverse organisms. Insect larvae rely on input from the chemosensory system, mainly olfaction, for locating food sources.

Journal of Limnology, 2018 Except for one unconfirmed case, chironomid larvae have been reported to pass through four larval instars between egg and pupal stages. We have observed a fifth larval instar to be a standard life-cycle feature of the podonomine Trichotanypus alaskensis ...

Biology, 2022 Ecdysone-induced protein 93F (E93) plays triple roles during post-embryonic development in insects whose juvenile instars are more than four. However, it only acts as a specifier of adult structures in Drosophila flies whose larval instars are fixed at ...
