Mate recognition and reproductive isolation in the sibling species Spodoptera littoralis and Spodoptera litura

open access: yesFrontiers in Ecology and Evolution, 2014
Mate recognition is crucial for reproductive isolation and for maintaining species integrity. Chemosensory-mediated sexual communication with pheromones is an essential component of mate recognition in moths.

The predatory behavior of ants: an impressive panoply of morphological adaptations

open access: yesInsect Science, EarlyView.
This review focuses on predation in ants, showing the wide diversity of cases from solitary foraging to group hunting tactics, as well as the evolution of mandible shape frequently adapted to capture specific prey. Although most ants are generalist feeders, finding their sugary substances directly on plants or indirectly via sap‐sucking insects, some ...

The male sex pheromone darcin stimulates hippocampal neurogenesis and cell proliferation in the subventricular zone in female mice

open access: yesFrontiers in Behavioral Neuroscience, 2015
The integration of newly generated neurons persists throughout life in the mammalian olfactory bulb and hippocampus, regions involved in olfactory and spatial learning.

The role of the male produced pheromone in the reproduction behaviour of the southern armyworm Pseudaletia separata (Wlk.) : a thesis presented in partial fulfilment of the requirements for the degree of Master of Science in Zoology. [PDF]

open access: yes, 1971
Detailed courtship patterns have been described for few species of Lepidoptera. Most of the descriptive work in the literature is fragmentary or lacking in experimental or statistical analysis.

Silencing of juvenile hormone‐related genes through RNA interference leads to molt failure and high mortality in the spongy moth

open access: yesInsect Science, EarlyView.
The feasibility of using RNA interference to control the globally important quarantine pest, the spongy moth. Targeting genes related to JHs play an important role in the growth and development of insects. First, the open reading frames (ORFs) of Ldjhamt and Ldjheh were identified and characterized, and the target genes were cloned and double‐stranded ...

Pheromone use for insect control: present status and prospect in Bangladesh

open access: yesInternational Journal of Agricultural Research, Innovation and Technology, 2012
The insect’s world is filled with many odors. Insects use these odors to cue them in a variety of complex social behaviors, including courtship, mating, and egg laying.

Offspring performance does not explain oviposition preference in the leafminer Stigmella sorbi (Lepidoptera: Nepticulidae): a tri‐trophic perspective

open access: yesInsect Science, EarlyView.
We studied oviposition site selection in a leaf‐mining moth (Stigmella sorbi) on rowan trees (Sorbus aucuparia) in northwestern Russia, assessing larval performance across different shoot types, leaf positions, and leaflets. Larval survival was highest on long vegetative shoots, yet females showed no preference for these optimal sites.

Chromosome‐scale genome assembly of the South American fruit fly, Anastrepha fraterculus sp.1

open access: yesInsect Science, EarlyView.
Anastrepha fraterculus sp. 1 is a major fruit fly pest in Argentina, currently controlled through chemical treatments and traps. This study aims to enhance the genomic understanding of this species to support the development of sterile insect technique as well as the use of innovative technologies.
