Understanding biological control function and trophic interaction dynamics of an artificially released predatory bug by DNA metabarcoding

open access: yesInsect Science, EarlyView.
This study investigated the dietary composition of Sycanus bifidus, a generalist predator of the assassin bug that is artificially released into citrus orchards, and uncovered its trophic structure across various pest species using metabarcoding‐based molecular gut content analysis.

Molecular mechanisms of sex determination in Lepidoptera: current status and perspectives

open access: yesInsect Science, EarlyView.
The genetic basis of sex determination in Lepidoptera was discovered in 2014 in the silkworm Bombyx mori. In this model species, the W chromosome‐derived small piRNA called Fem piRNA downregulates the expression of a Z‐linked gene, Masculinizer (Masc), which leads to the default female‐specific splicing of the doublesex gene (dsxF) and thus to female ...

Changes in the calling behaviour of female Spodoptera littoralis (Lepidoptera: Noctuidae) as a function of body weight and adult feeding

open access: yesEuropean Journal of Entomology, 2012
Because nutrients accrued during larval stages represent the major limiting factor for egg production, the use of adult feeding to enhance the reproductive output in moths is considered to be largely weight-dependent.

Taxonomic and functional diversity of noctuoid moths in a Mediterranean coastal area: implications for dune conservation in a long‐term ecological research eLTER site

open access: yesInsect Science, EarlyView.
This study investigates the taxonomic and functional diversity of noctuoid moths in a protected coastal dune system in Central Italy, revealing strong ecological associations between moth assemblages and dune zonation. Differences in species composition and trait attributes, along with the presence of habitat‐exclusive species, highlight the role of ...

Expression of cytochrome P450 CYP6B6 in the different developmental stages of the insect Helicoverpa armigera (Lepidoptera: Noctuidae)

open access: yesEuropean Journal of Entomology, 2013
In order to determine when during the development of H. armigera CYP6B6 is expressed, we measured the width of the head capsule, the length of the body and weight of the different life stages of the cotton bollworm reared under laboratory condition.

Beauveria Bassiana Triggers Soybean Systemic Resistance and Causes Sublethal Effects in Spodoptera frugiperda

open access: yesEntomologia Experimentalis et Applicata, EarlyView.
The interaction of soybean plant and the endophytic microorganism Beauveria bassiana was evaluated by inoculating a single trifoliate leaf. The effects of this inoculation on the herbivory, larval development, and life traits of Spodoptera frugiperda were measured.

RNA interference mediated knockdown of an inhibitor of apoptosis protein induces apoptosis in Mythimna separata (Lepidoptera: Noctuidae)

open access: yesEuropean Journal of Entomology, 2018
Coordinated regulation of apoptosis is critical for development, homeostasis, and immunity in larvae of Metazoa. We determined the full nucleotide sequence of an inhibitor of an apoptosis protein in a lepidopteran insect Mythimna separata (Walker) (MsIAP)

Performance of Fall Armyworm Spodoptera frugiperda Reared on Various Horticultural Crops

open access: yesEntomologia Experimentalis et Applicata, EarlyView.
The developmental performance and reproductive success of the Australian population of fall armyworm (Spodoptera frugiperda) were evaluated on five horticultural crops under laboratory conditions. Sweetcorn and bean supported rapid development, lower mortality, and higher fecundity (good performance); whereas capsicum, strawberry, and okra resulted in ...
