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

Studies on Egg Quality: II Seasonal Variations in Yolk Color
Poultry Science, 1927 Abstract Part I 2 of these studies dealt with the practical and theoretical importance of questions of “egg quality,” including under the term such characteristics as yolk color, albumen color and consistency, shell thickness and texture, and the like. It also contained a brief review of the literature of one phase of the subject, that of yolk color;

Breed and feed affect amino acid contents of egg yolk and eggshell color in chickens
Poultry Science, 2020 Genetic and environmental factors regulate hen egg traits. To demonstrate the possibility of producing designer eggs through genetic and environmental factors, we investigated the effects of breed and feed on egg traits using 2 chicken breeds, Rhode Island Red (RIR) and Australorp (AUS), and 2 feeds, mixed feed and fermented feed.

Iflaviruses in arthropods: when small is mighty
Insect 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.

Performance and egg quality of laying hens fed with mineral sources and rosemary oil
Anais da Academia Brasileira de Ciências, 2019 In order to evaluate the effect of rosemary oil and micro mineral sources on the performance and egg quality of laying hens, 288 hens were used and distributed in a completely randomized design using a 2x3 factorial (mineral sources x rosemary oil) with ...

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

Insect 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.
