Extreme Silk Toughness in Caerostris Spiders Is Limited to Adult Females

open access: yesIntegrative Zoology, EarlyView.
We ask whether species with exceptionally tough silk, like Caerostris bark spiders, show different developmental patterns in silk toughness between ontogenetic stages and sexes. We found that only large females produce exceptionally tough silk with higher initial stiffness, while juvenile females as well as adult and juvenile males produce inferior ...

Predation efficiency of Mesocyclops leuckarti on first instar mosquito larvae.

open access: yesThe Journal of communicable diseases, 1994
This study provides an indication of predatory behaviour of Mesocyclops leuckarti sensu lato against first instar larvae of Culex quinquefasciatus. The predatory potentiality of M. leuckarti was tested by 'No choice' and 'choice' experiments. The predation rate increased with increase in prey density and hunger state of the predator and decreased with ...

Multi‐Omics Analysis Reveals Coordinated Adaptations in Genes, Metabolism, and Gut Microbiota Underpinning Herbivory in Lordiphosa Flies

open access: yesIntegrative Zoology, EarlyView.
Multi‐omics analysis reveals that herbivorous adaptation in Lordiphosa flies arises from coordinated interactions across the genome, transcriptome, and gut microbiota: genomic expansions of detoxification (e.g., cytochrome P450s) and carbohydrate metabolism gene families, transcriptomic upregulation of energy pathways like lipid oxidation and ...

It's Complicated: How Sex, Family, and Season Affect Growth of a Sexually Size Dimorphic Spider

open access: yesIntegrative Zoology, EarlyView.
Extreme female‐biased sexual size dimorphism (SSD) in Nephilingis cruentata emerges when male and female growth trajectories diverge mid‐development. Seasonal effects influence both sexes similarly, but family effects are strongly sex‐specific. These patterns identify a critical developmental window for mechanistic studies of SSD.

Efficiency of neem oil nanoformulations to Bemisia tabaci (GENN.) Biotype B (Hemiptera: Aleyrodidae)
Eficiência de nanoformulações a base de óleo de nim sobre Bemisia tabaci (GENN.) Biótipo B (Hemiptera: Aleyrodidae)

open access: yesSemina: Ciências Agrárias, 2012
The nanotechnology, through encapsulation of active ingredients, has showed an important way to avoid problems with quickly degradation of the pesticide molecules.

Assessing the host plants of the invasive apricot aphid, Myzus mumecola (Hemiptera: Aphididae)

open access: yesAgricultural and Forest Entomology, EarlyView.
We investigated the host plants of the invasive apricot aphid Myzus mumecola (Hemiptera: Aphididae), an emerging pest species in Europe, by combining molecular and ecological approaches. The winter host plant was confirmed as apricot by both methods.

[Experimental infestation of goats with first instar larvae of Oestrus ovis].

open access: yesVeterinary research, 1997
A protocol of experimental infection with OEstrus ovis larvae L1 was applied to kids in order to study their susceptibility to OEstrus ovis. Two-month-old kids, born and raised indoors during winter, were infected with single or repeated administrations of OEstrus ovis L1.
