Variations of Egg Yolk Color and Characteristics Produced by Feeding and Environment

open access: yesPoultry Science, 1935
Abstract ELEVEN farms were visited during the spring and summer of 1932 and 1933 and eggs were secured from each for studying the storage quality. Eggs were also obtained from three additional farms which were not visited. The general location of the ground used by the chickens, feed, management of the flocks, housing conditions care of eggs, health ...

The transformer gene controls sexual development in Drosophila suzukii

open access: yesInsect Science, EarlyView.
The transformer gene plays a key role in the genetic pathway for sexual development in Drosophila suzukii Abstract The genetic network of sex determination in the model organism Drosophila melanogaster was investigated in great detail. Such knowledge not only advances our understanding of the evolution and regulation of sexual dimorphism in insects ...

Molecular characterization of transformer, transformer‐2, and doublesex genes in the carambola fruit fly, Bactrocera carambolae, revealing potential for genetic pest management

open access: yesInsect Science, EarlyView.
Abstract Globalization and climate change may be driving the spread of the quarantine fruit fly, Bactrocera carambolae, highlighting the need for ecofriendly control methods like the Sterile Insect Technique (SIT), which relies on releasing sterile males to reduce wild populations.

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.

Iflaviruses in arthropods: when small is mighty

open access: yesInsect Science, EarlyView.
Many arthropod species harbor iflaviruses, which often cause covert (asymptomatic) infections, but may still affect host fitness. We review the impact of iflaviruses on arthropod fitness, immunity, behaviour as well as the iflavirus’ host range, transmission, tissue tropism and the interactions with other microorganisms within arthropods.

Effects of Age, Housing Environment, and Strain on Physical Egg Quality Parameters of Laying Hens [PDF]

open access: yesBrazilian Journal of Poultry Science
This study examined the effects of age, housing environment, and strain (Lohmann Sandy (LS) and Lohmann LSL Classic (LW)) on egg quality traits. Deep litter (DL), free access to outdoor Mentha piperita (MP), Petroselinum crispum (PC), and Medicago sativa

CRISPR/Cas9‐based white pupae mutant lines in Bactrocera spp. for sterile insect technique applications

open access: yesInsect Science, EarlyView.
Bactrocera fruit flies are significant horticultural pests that cause major economic losses. A “neoclassical approach” incorporating genome editing via CRISPR/Cas9 to develop genetic sexing strains (GSS) could render the sterile insect technique (SIT) against these pests more efficient and cost‐effective.
