Potential of cyclodextrin-based formulations of essential oils in the control of the date moth (Pyralidae).

Recently essential oils (EOs) encapsulation is experiencing growing applications in agricultural and agri-food sector. Encapsulation is reported as safe environmental technology leading to a reduction of conventional insecticides use. This study concerns the assessment of fumigant toxicity and persistence of EO encapsulated in two cyclodextrins β-CD and HP-β-CD against larvae of the date moth, The retention capacity, encapsulation efficacy, loading capacity and release behavior of the two inclusion complexes were investigated.

The Maize Caterpillar (= ) (Duponchel, 1827) (Lepidoptera: Noctuidae): Identification, Distribution, Population Density and Damage in Tunisia.

Surveys were conducted during 2020 and 2021 to study the emerging lepidopteran pests inflicting cereals in Tunisia, with specific emphasis on maize and sorghum crops. A species was collected from traps placed in the Jendouba, Bizerte, Nabeul and Gabes regions. Thus, this study carried out first report on its identification, distribution, population density and damage.

Eco-friendly management strategies of insect pests: long-term performance of rosemary essential oil encapsulated into chitosan and gum Arabic.

This study focused on encapsulation of Rosmarinus officinalis essential oil (EO) on chitosan and gum Arabic matrix in various ratios and with varying essential oil concentrations. Additionally, UV/VIS spectroscopy was used to determine cumulative-release profiles. The insecticidal activity was tested against and , both pests of stored products.

Encapsulation of Rosmarinus officinalis essential oil and of its main components in cyclodextrin: application to the control of the date moth Ectomyelois ceratoniae (Pyralidae).

Background: Synthetic insecticides are the most useful tools for preventing losses caused by insect pest's infestation during storage. However, the use of pesticides should be limited because of the development of insect resistance and their adverse effects on human health and environment. In the last decades, natural insecticidal products, principally essential oils (EOs) and their active components, exhibited potential alternatives for pest control.

Screening for insecticidal toxicity of (L.) bulbs and (L.) tubers for the control of (Tenebrionidae).

This research was conducted to determine the effect of geographical distribution on morphological characteristics of plants and some chemical compounds such as polyphenols. Moreover, we explore the contact toxicity of ethanolic and methanolic extracts from bulbs and tubers collected from three localities in the North West of Tunisia against adults. The toxicity results demonstrated that both of the studied plant extracts had an effective control against at concentration 7.

Laurel essential oil: biological activities and application for semolina preservation against the red flour beetle (Tenebrionidae).

The phytochemical composition of essential oil and their anticholinesterase, antioxidant, and insecticidal potential were studied. Also, the oil volatile fraction was compared in semolina at the beginning and after storage periods. For that, a headspace solid-phase-microextraction analysis (HS-SPME) coupled with gas chromatography and mass spectrometry was undertaken.

Insights for the control of dried-fruit beetle (Nitidulidae) using rosemary essential oil loaded in chitosan nanoparticles.

Natural insecticidal products, essentially essential oils and their bioactive compounds are available as an excellent alternative method to control insect pests as well as they are less toxic to human health. However, due to their volatile constituents, encapsulation could be considered as the most suitable solution for their practical application. Therefore, this study aims to explore the insecticidal toxicity of chitosan nanoparticles loaded with essential oil against adults of .

In Vitro Potential of Clary Sage and Coriander Essential Oils as Crop Protection and Post-Harvest Decay Control Products.

Owing to their various application fields and biological properties, natural products and essential oils (EO) in particular are nowadays attracting more attention as alternative methods to control plant pathogens and pests, weeds, and for post-harvest applications. Additionally, to overcome EO stability issues and low persistence of effects, EO encapsulation in -cyclodextrin (-CD) could represent a promising avenue. Thus, in this work, the EO distilled from two aromatic plants ( L.

Cryptic Diversity Hidden within the Leafminer Genus (Diptera: Agromyzidae).

Leafminer insects of the genus are small flies whose larvae feed on the internal tissue of some of the most important crop plants for the human diet. Several of these pest species are highly uniform from the morphological point of view, meaning molecular data represents the only reliable taxonomic tool useful to define cryptic boundaries. In this study, both mitochondrial and nuclear molecular markers have been applied to investigate the population genetics of some Tunisian populations of the polyphagous species , one of the most important pest of chickpea cultivars in the whole Mediterranean region.
