The Effects of Insecticide Treated Netting on Male-Female Interactions in Red Flour Beetles [PDF]

open access: yes, 2018
Courtship behaviors take place before and after copulation for the purpose of stimulating the female (Evardsson & Arnqvist 2000). Females will mate with different males within minutes of the first copulation (Pai &Yan 2003), with males showing a ...

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 ...

Evaluación de la acción insecticida de la rapanona sobre Tribolium castaneum (Herbst)

open access: yesActa Biológica Colombiana, 1992
Experiments were carried out to detect and estimate the insect-killing effect of rapanone on the flour beetle  T.castaneum. Two kinds ofessays were made: by ingestion and by contacto It was proved that rapanone has insecticide activity on T.

Study on the Distribution Characteristics of Tribolium Castaneum in Wheat Grain Heap

open access: yesLiang you shipin ke-ji
Using a new type of insect probe trap, the activity and distribution of Tribolium castaneum in wheat grain bulks inside experimental silos were collected and analyzed to investigate its distribution patterns and main influencing factors within the grain ...

Genetic engineering for SIT application: a fruit fly‐focused review

open access: yesInsect Science, EarlyView.
Abstract Sterile insect technique (SIT) has become a key component of efficient pest control. Fruit fly pests from the Drosophilidae and Tephritidae families pose a substantial and overwhelmingly increasing threat to the agricultural industry, aggravated by climate change and globalization among other contributors.

Oviposition Decisions by Red Flour Beetle [Tribolium castaneum] [PDF]

open access: yes, 2018
The red flour beetle [Tribolium castaneum] and the confused flour beetle [Tribolium confusum] are very important flour pest. We tested if the red flour beetle can discriminate between flour infested by the same species or congeneric species and lay ...

Future trends in Animal Breeding due to new genetic tecnologies

open access: yes, 2011
The Darwin theory of evolution by natural selection is based on three principles: (a) variation; (b) inheritance; and (c) natural selection. Here, I take these principles as an excuse to review some topics related to the future research prospects in ...

RNA interference : a promising biopesticide strategy against the African sweetpotato weevil Cylas brunneus [PDF]

open access: yes, 2016
The African sweetpotato weevil Cylas brunneus is one of the most devastating pests affecting the production of sweetpotatoes, an important staple food in Sub-Saharan Africa. Current available control methods against this coleopteran pest are limited.

Selection, counterselection, and conditional gene expression for genetic biocontrol of insects

open access: yesInsect Science, EarlyView.
Selection, counterselection, and conditional expression can be used for sex separation. Selection (S) and counterselection (CS) genes are linked to the sex chromosomes (e.g., the X and Y chromosomes) to confer sex‐specific selection or counterselection based on the presence or absence of the S or CS genes.
