CNN–SVM: a classification method for fruit fly image with the complex background

open access: yesIET Cyber-Physical Systems, 2020
On the basis of the problem that the image background is simple and the traditional shooting equipment of fruit flies is too high, this study improved the convolutional neural network model. First, the authors changed Softmax classifier to support vector

Taxonomic identity of the invasive fruit fly pest, Bactrocera invadens: concordance in morphometry and DNA barcoding. [PDF]

open access: yesPLoS ONE, 2012
In 2003, a new fruit fly pest species was recorded for the first time in Kenya and has subsequently been found in 28 countries across tropical Africa. The insect was described as Bactrocera invadens, due to its rapid invasion of the African continent. In

Phylogenetic relationship and characterization of the complete mitochondrial genome of Bactrocera caudata (Diptera: Tephritidae) from China

open access: yesMitochondrial DNA. Part B. Resources, 2020
The complete mitochondrial genome (mitogenome) of Bactrocera caudata (Diptera: Tephritidae: Dacinae) was sequenced and annotated. The mitochondrial genome is 15,311 bp (GenBank No. MT180970), containing 72.7% A + T (A 39.1%, C 17.0%, G 10.3%, and T 33.6%)

The South American fruit fly : an important pest insect with RNAi-sensitive larval stages [PDF]

open access: yes, 2019
RNA interference (RNAi) technology has been used in the development of approaches for pest control. The presence of some essential genes, the so-called "core genes," in the RNAi machinery is crucial for its efficiency and robust response in gene ...

Insights into pupal development of Bactrocera dorsalis: factors influencing eclosion. [PDF]

open access: yesSci Rep
In the life cycle of the oriental fruit fly where larvae reside within fruits and adults exhibit high activity, the pupal stage occurs in the soil, closely tied to agricultural soil management. This study investigates the impact of four variables (body orientation, burial depth, soil particle size, and pH) on Bactrocera dorsalis' physiological ...

A role of corazonin receptor in larval-pupal transition and pupariation in the oriental fruit fly Bactrocera dorsalis (Hendel) (Diptera: Tephritidae) [PDF]

open access: yes, 2017
Corazonin (Crz) is a neuropeptide hormone, but also a neuropeptide modulator that is internally released within the CNS, and it has a widespread distribution in insects with diverse physiological functions.

The Impact of Predation Risks on the Development and Fecundity of Bactrocera dorsalis Hendel. [PDF]

open access: yesInsects
Predators are dependent on the capture of prey to meet their energetic and nutritive requirements, which brings the risk of predation to prey. The predation risk is divided into consumptive and non-consumptive effects. Non-consumptive effects may manifest through altered growth and ontogenetic trajectories in prey species, a dynamic modulated by ...

Reduced glutamine synthetase activity alters the fecundity of female Bactrocera dorsalis (Hendel) [PDF]

open access: yes, 2019
Glutamine synthetase (GS) is a key enzyme in glutamine synthesis and is associated with multiple physiological processes in insects, such as embryonic development, heat shock response, and fecundity regulation.
