“…In agreement with this finding, nymph mortality of D. opuntia was high, ranging from 40 to 60% at different cultivars, during the first 24 days of development(Me ´ndez-Gallegos et al, 2010) Akroud et al (2021). found that mortality of D. opuntiae, started on the 7 th day after infestation and maximum mortality on the 28 th day.…”

“…Méndez-Gallegos et al (2010) explained that 'Blanco Moscatel' and 'Colorado Moscatel' cultivars might have defense means for D. coccus, since the colony development on those hosts showed a high mortality rate and failed to reproduce. This behaviour may be associated with the presence of phytochemicals (such as terpenoids, flavonoids, tannins, and polyphenols) (Akroud et al, 2021;Guevara-Figueroa et al, 2010;Matos et al, 2021) and morphological-histological characteristics (epidermis and cuticle thickness and density of calcium oxalates) (da Silva et al, 2010). Host resistance should be considered in cochineal control (Vigueras and Portillo, 2014).…”

Opuntia ficus-indica (L.) Mill.), is called "beles" in the Tigray region of Ethiopia, where it is used for multiple purposes, such as food, fodder, and fences; however, in recent years the introduction of the cochineal (Dactylopius coccus Costa) to this region has caused it to become a plague that has affected thousands of hectares, causing an economic and social problem. Six cultivars: three from Opuntia ficus-indica (‘Atlixco’, ‘Chicomostoc’, and ‘Rojo Pelón’) and three others O. cochenillifera (‘Nopalea’ and ‘Bioplástico’) and O. robusta (‘Robusta’) were tested for resistance to D. coccus in completely randomized design (CRD) experiment with six replications under greenhouse conditions, for two seasons (cycles). Matured cladodes were infested by attaching a paper bag with ten ovipositing female D. coccus. The number of insects at different stages and yields were recorded, log transformed (insect count data), and subjected to statistical analysis. The number of nymphs (stages I and II) was significantly different in both cycles (P=0.0000). The insects died at the nymph I stage at ‘Rojo Pelón’ and ‘Robusta’, in contrast, they completed their life cycle at ‘Atlixco’, ‘Chicomostoc’, and ‘Nopalea’ cultivars. Insects at ‘Bioplástico’ cultivar remained in the nymph I stage the whole experimental period; the molting was hampered. Although some crawlers started settling (nymph I) at ‘Rojo Pelón’, they couldn’t survive and developed, and this confirms that this O. ficus-indica cultivar is resistant to D. coccus.

“…2). The most outstanding areas were focused, primarily, on biological control through predators and entomopathogens After the tactics reported as most frequent, studies about plant resistance also stood out, with 13 % (Palacios- Mendoza et al 2004;Vigueras et al 2009; Passos da Silva et al 2009;Sbaghi et al 2019;Akroud et al 2021;da Silva et al 2021). It is important to highlight that some essential tactics, such as legal control, ethological control, and mechanical control, were also common practices in many areas (Moran and Hoffmann 1987;Macêdo et al 2014;da Silva et al 2010;.…”

The objective of this article is to identify the growth, control tactics, collaboration among authors, and emerging trends in scientific research related to the control strategies of Dactylopius opuntiae Cockerell (Hemiptera: Dactylopiidae) through bibliometric indicators. In order to recover the relevant academic articles on the topic, six referential databases were consulted. The keyword used to retrieve bibliographic information was «Dactylopius opuntiae» in the search fields: title, abstract and keywords. 1 212 bibliographic records were obtained, which were sent to the Zotero software, and subsequently reviewed to discard repeated records unrelated to the topic, obtaining only 99 from 1848 to 2022. These records resulted in four bibliometric indicators using Excel and VOSviewer. The dynamic of scientific production has been more evident during the last seven years. Biological control, through predators and entomopathogens, was the most studied emergent research theme. From 1848 to 2000, only 12 documents of scientific production about D. opuntiae control tactics were found; production has been increasing by a greater proportion from 2016 up to 2022. The most outstanding control tactics were focused on biological control and non-conventional chemical control using various products such as oils, plant extracts, soaps, and detergents. Finally, the most frequently mentioned research topic was «biological control». Among other conclusions, the most researched topics were biological control agents (predators and entomopathogens) and plant resistance, which stood out as the tactic that could be most sustainable.

“…As D. opuntiae presents a serious and growing risk to prickly pear cultivation in Morocco and other Mediterranean countries (Aalaoui and Sbaghi, 2021;Akroud et al, 2021), this research aims to promote plants as biopesticides against this pest by saving the environment from toxic pesticides, protecting cactus pear cultivation, and using the country's natural diversity of species to eliminate this dangerous insect.…”

Morocco's prickly pear has high economic value. However, it’s infected by the cochineal Dactylopius opuntiae, causing massive losses. Thus, the present work aims to study insecticidal effect of bioactive natural extracts. Essential oils and hydrosols of oregano (Origanum vulgare), thyme (Thymus vulgaris), pennyroyal (Mentha pulegium) and peppermint (Mentha piperita) were tested. Two concentrations were used for essential oils (1.5% and 3%) and for hydrosols (100% and 75%) with contact and fumigant application. Mortality rate was determined after 24h of treatment. Highest values were recorded at 3% E.O concentration with contact assay comparing to fumigation. As it’s EO (99.44%), O. vulgare hydrosol has significant insecticidal activity reaching 80% of mortality rate. Chemical composition of essential oils using Gas Chromatography coupled to Mass Spectrometry (GC/MS) was studied. Bioactive compounds include carvacrol and m-cymene (O. vulgare and T. vulgaris), pulegone and l-menthone (M. pulegium) and Linalool and linalyl acetate (M. piperita). Data obtained relieved the importance of these plants as source of natural bioactive compounds against D. opuntiae.
