First records of Agnidra vinacea (Moore, 1879) (Lepidoptera: Drepanidae: Drepaninae) from the western Himalaya, extending its known range westwards

Journal of Threatened Taxa, 2019
Reporting the range extension of Agnidra vinacea (Moore, 1879) from eastern Himalayas to Uttarakhand, western Himalayas.  The individuals of the species were documented from western Himalayas by both opportunistic sighting and light-trapping method by ...

A preventive strategy for the control of aphids in sweet pepper using lacewings and micrococcinelid beetles

Insect Science, EarlyView.
Aphids pose a serious risk to horticultural crops. Current biocontrol strategies often fail due to the poor establishment of natural enemies when aphids are scarce. We evaluated the potential of two aphidophagous predators, Micromus variegatus and Scymnus interruptus, to be used as preventive biocontrol agents, released before aphid infestation.

A taste for fruit: first record of Rekoa marius (Lucas, 1857) (Lepidoptera: Lycaenidae: Eumaeini) on Averrhoa carambola L. (Oxalidales: Oxalidaceae)

Revista Chilena de Entomología
Information on the natural history of Rekoa marius (Lucas, 1857) is presented through the first record of the species on Averrhoa carambola L. The larvae of this lepidopteran were collected on A. carambola and reared under laboratory conditions.

Genetic and phenotypic variation in wood tiger moths from the Caucasus: insights into male warning color variation

Insect Science, EarlyView.
Coloration serves several fitness‐related functions, including thermoregulation, immunity, social signaling, sexual selection, and predator avoidance. Consequently, color polymorphism can have a significant impact on a species’ interactions with its environment, including its relationships with predators, prey, and potential mates. The wood tiger moth (

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

Insect 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 ...

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

Insect 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 ...

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

Insect 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.

From the predator to the prey: a case study of the vulnerability of Harmonia axyridis to aggressive competitors

Insect Science, EarlyView.
The level of aggressiveness of an individual is a factor that shapes intraguild predation (IGP) interactions. In Nabis americoferus, high aggressiveness leads to an increase in attack rate and IGP against Harmonia axyridis. Moreover, the absence of extraguild prey seems to exacerbate IGP. In docile N.

IAEA Coordinated Research Project on “A generic approach for the development of genetic sexing strains for Sterile Insect Technique applications”— an overview

Insect Science, EarlyView.
Abstract The sterile insect technique (SIT) plays an important role in environmentally sustainable pest management. Its effectiveness hinges on specialized genetic tools called genetic sexing strains (GSSs), which enable the production and release of sterile male insects while excluding females.

First record of host plant for Cogia stylites (Herrich-Schäffer, 1869) (Hesperiidae: Eudaminae)

Historia naturalis bulgarica
This paper reports the butterfly Cogia stylites (Herrich-Schäffer, 1869) feeding on a Fabaceae tree species in Curitiba, Paraná, Brazil. The immature specimen was found inside its shelter, constructed using leaflets from the host plant identified as ...
