Assessing Larval Toxicity of Sphaeranthus Indicus Linn Essential Oil Against Dengue and Filarial Vectors [PDF]

E3S Web of Conferences
This study focuses on a crucial objective: eradicating the formidable dengue and filarial vectors through larval toxicity using a novel essential oil derived from Sphaeranthus indicus Linn.

Decrease of fluctuating asymmetry among larval instars in an aquatic, holometabolous insect

Comptes Rendus. Biologies, 2005
The use of fluctuating asymmetry (FA) to reveal environmental stress in natural populations has been investigated extensively over the past decade. In aquatic ecosystems, many investigations involve amphibiotic insects with larval development stages in freshwater.

Significant resource niche overlap between competing parasitoids does not prevent their successful co‐existence

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Different species that exploit the same resources can sometimes co‐exist in the same habitat through resource sharing. For example, if resources are superabundant, then they can be easily partitioned interspecifically among different individuals. However, when resources

Developmental cost of leg-regenerated Coccinella septempunctata (Coleoptera: Coccinellidae).

PLoS ONE, 2019
As larval cannibalism is common under intensive rearing conditions, leg regeneration can help ladybugs adapt to the competitive environment, but whether the leg regeneration leads to side effects on development remains unclear. To analyze the potentially

Inducible defences, chemical aposematism and the spatial ecology of plant–herbivore interactions in tall goldenrod, Solidago altissima L.

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Plants can respond to herbivore attack by inducing resistance traits that affect subsequent herbivore performance and behaviour. Here, we investigate how such induced responses in Solidago altissima L.

Jumping plant-lice of the Paurocephalinae (Insecta, Hemiptera, Psylloidea): systematics and phylogeny [PDF]

, 2003
Much confusion exists with respect to the content and definition of the psyUid subfamily Paurocephalinae. Based on a cladistic analysis of 22 morphological characters (16 adult and 6 larval), the subfamily is redefined to comprise the following five ...

Generation cycles in experimental populations of a multivoltine insect

Journal of Animal Ecology, EarlyView.
Although theory suggests various mechanisms by which environmental and ecological factors may drive generational fluctuations, our field‐cage experiment is the first to demonstrate how internal dynamics and external disturbances jointly produce synchronised, large‐scale outbreak cycles.

Larval biometry of Simulium rubrithorax (Diptera: Simuliidae) and size comparison between populations in the states of Minas Gerais and Roraima, Brazil

Memorias do Instituto Oswaldo Cruz, 2003
The number of larval instars of Simulium (Hemicnetha) rubrithorax Lutz (Diptera: Nematocera) was determined using the lateral length of the head capsule. In this study 1,035 larvae, of different sizes, were measured (639 from the state of Roraima and 396

Recovery of male DNA acquired from carrion‐feeding insects in a simulated sexual assault scenario

Journal of Forensic Sciences, EarlyView.
Abstract When bodies of sexual assault victims are discovered in advanced stages of decomposition, the recovery of direct DNA evidence is often compromised, posing a challenge in criminal investigations. This study aimed to determine insect colonization and succession patterns on pig carcasses inoculated with semen and to assess the feasibility of ...

Cold storage effects on immature calliphoridae: Survival limits and forensic consequences for PMI estimation

Journal of Forensic Sciences, EarlyView.
Abstract This study investigated the effects of continuous refrigeration (4°C ± 2°C and 50% ± 5% RH) on the development and survival of immature stages (eggs, first, second, and third instar larvae, and pupae) of four forensically important blowfly species (Chrysomya megacephala, Chrysomya putoria, Hemilucilia segmentaria, and Lucilia cuprina) compared
