... Our previous study was conducted to investigate the field biology and fluctuation of L. algirus using two local faba bean varieties at Douyet Station in Sais region, and it showed a positive correlation between the mean number of eggs and total rainfall. In addition, the number of pupae and relative humidity was negatively correlated [16]. ...

The stem borer weevil, Lixus algirus L. (Coleoptera: Curculionidae), causes severe damage to faba beans (Vicia faba L.) in Morocco. A survey was conducted to determine the distribution of L. algirus, its natural enemies, and the severity of damage it causes to faba beans in Morocco. A total of 16 and 27 stops were randomly selected and surveyed in the major faba bean-growing regions during the years 2017 and 2018, respectively. The Gharb region recorded the highest level of L. algirus infestation at 80% and 71.42% in 2017 and 2018, respectively, followed by the Saïs region at 58.75% and 36% in 2017 and 2018, respectively. Two egg parasitoids (Chlorocytus lixi and Anaphes longicornis), one
egg predator (Orius sp.), and a larval parasitoid (Cyanopterobracon) were identified. The ectoparasitoid C. lixi was observed to be the most dominant species, with percentages of parasitism in the regions ranging between 35.75% and 70.49%. The larval parasitoid Cyanopterobracon was the second most abundant species, with percentages of parasitism ranging between 3.03% to 15.96%. Understanding the parasitoid complex of L. algirus in Morocco is necessary for the subsequent development of a biological control program.
... It is noteworthy that the stem borer, Lixus algirus is the major insect pest of faba bean in the Mediterranean region (Taadaouit et al., 2021), Larinus latus is an agent of biological pest control against Onopordum thistles in Australia (Pettit and Briese, 2000), while Leucomigus candidatus is protected by the Red Data Book of Ukraine (Akimov, 2009). ...
Present paper reports observations on the digger wasp Cerceris tuberculata (Villers, 1787) (Hymenoptera: Crabronidae), listed in Red Data Book of Ukraine, its parasitoids and prey. The observations revealed two parasitoids associated with this wasp: a cuckoo wasp Hedychrum virens Dahlbom, 1845 (Chrysididae) and velvet ant Nemka viduata viduata (Pallas, 1773) (Mutillidae). The host-parasitoid association of this velvet ant and C. tuberculata is provided for the first time. Four species of weevils were registered as a prey of C. tuberculata, three of them are given for the first time herein. New records of the species from Zaporizhzhya and Kherson Regions are provided; the species is reported from Zaporizhzhia Region for the first time.
Cool season legumes (Faba bean, chickpea, lentil, pea, and grass pea) are important protein harvests for food and nutrition security in many countries. They play key roles in sustainable cereal production through their ecological benefits. However, diseases and pests attack continue to have a substantial impact on crop yield and quality. Although growers used different control options to manage these biotic stresses such as pesticide application, cultural practices, and resistant varieties, there is a pressing need for the development of new, more cost-effective and environmentally friendly solution to help farmers in facing the existing environmental issues. Recently, there is a growing interest among researchers in exploiting Volatile Organic Compounds (VOCs) for the elaboration of disease and pest control strategies in food legumes and other crops. These compounds have important functions in ecological relationships occurring between plants and their surrounding environment, as well as plants and others species, such as pests and pathogens. Due to their unique properties, VOCs can be employed in improving management alternatives for food legume diseases and pests. In this assessment, we investigated the role of VOCs in plant-pest and plant-pathogen interactions and their present applications in pest and diseases control strategies. We emphasized the ecological importance of employing plant VOCs in legume farming and crop breeding. Additionally, we highlighted the potential of microbial VOCs in facilitating microbe-microbe, microbe-plant and microbe-plant-pest interactions, along with their role in food legume protection.
The pea leaf weevil, Sitona lineatus L. (Coleoptera: Curculionidae, PLW), is a significant insect pest of pea (Pisum
sativum L.) and faba bean (Vicia faba L.), and it is responsible for serious economic damages. The current study aims to investigate
the insecticidal activities of seven essential oil species on S. lineatus adults in the laboratory as well as the most effective ones under
growth chamber conditions. Out of the tested essential oils, Lavandula angustifolia Mill. and Mentha arvensis L. oils showed
substantial insecticidal activity against S. lineatus adults (100%) by contact activity at a concentration of 1.5% after 1 and 3 h of
application, respectively, with an estimated LC50 of 0.224 and 0.320% at 72 h after treatment, respectively. L. angustifolia essential oil
also resulted in a significant mortality rate of 70% by ingestion activity, with an LC50 of 1.340% at 48 h after application under
laboratory condition. The growth chamber bioassays confirmed these significant effects, displaying a mortality rate of 70% at 96 h
after application at 1.5%. The gas chromatography−mass spectrometry analysis showed that linalool acetate (32.91%) and linalool
(26.69%) dominated the L. angustifolia essential oil composition. These findings highlighted that L. angustifolia essential oils are
promising agents for the development of biopesticide formulation for the control of S. lineatus, as a safe and ecofriendly alternative
compared to chemical insecticides.
