Genetic relations among Moroccan Opuntia genotypes with different degrees of resistance to Dactylopius opuntiae

Journal of the Professional Association for Cactus Development, 2022
Genetic diversity and relationship among a set of 18 cactus pear genotypes, with different degrees of resistance to cochineal scale insect (Dactylopius opuntiae), was estimated using eight simple sequence repeat (SSR) markers. The genotypes used belong to four Opuntia species (O. engelmanii, O. ficus indica, O. robusta, and o. dillenii).

Toxicity of four commercial insecticides on Dactylopius opuntiae (Hemiptera: Dactylopiidae)

Journal of the Professional Association for Cactus Development, 2023
Dactylopius opuntiae (Cockerell) (Hemiptera: Dactylopiidae) is a pest of Opuntia ficus-indica (L.) Miller (Caryophyllales: Cactaceae) in many regions around the world, and there are no formal insecticide toxicity assays. This study aimed to evaluate the lethal toxicity of malathion, lambda-cyhalothrin, spirotetramat, and potassium salts on D.

First record of Dactylopius opuntiae (Cockerell) (Hemiptera: Coccoidea: Dactylopiidae) from Israel

Phytoparasitica, 2013
The presence of the Opuntia cochineal scale insect, Dactylopius opuntiae (Cockerell) (Hemiptera: Coccoidea: Dactylopiidae) is reported for the first time from Israel. It was collected off the Indian-fig prickly-pear, Opuntia ficus-indica (L.) Miller (Cactaceae) in the Hula Valley of the Upper Galilee.

Antibioisis and antixenosis resistance to Dactylopius opuntiae (Hemiptera: Dactylopiidae) in Moroccan cactus germplasm

Phytoparasitica, 2021
The wild cochineal, Dactylopius opuntiae (Cockerell), has become the main pest of the prickly pear [(Opuntia ficus-indica (L.) Miller] cactus crop in most of the Mediterranean countries, including Morocco since 2014. The use of D. opuntiae-resistant cactus ecotypes seems to be one of the most practical management option for the control of this pest ...

First report of the Opuntia cochineal scale Dactylopius opuntiae (Hemiptera: Dactylopiidae) in Morocco

EPPO Bulletin, 2016
The Opuntia cochineal scale Dactylopius opuntiae (Cockerell) (Hemiptera: Dactylopiidae) causes severe damage to prickly pear (Opuntia ficus‐indica (L.) Miller). This scale insect was first detected in Morocco in 2015 during sampling in the cactus crop in the Sidi Bennour region (120 km north‐west of Marrakech).

Optimized Ultrasound-Assisted Extraction of Carminic Acid from Dactylopius opuntiae

Journal of the Professional Association for Cactus Development
Dactylopius opuntiae is a major pest of prickly pear crops and has therefore been extensively studied with the aim of controlling its proliferation. However, it has largely been disregarded as a potential natural red pigment source, despite producing carminic acid (CA), as does Dactylopius coccus, albeit in lower amounts. CA, an anthraquinone compound,
