“…Another issue threatening chickpea quality is Callosobruchus maculatus (Fab.) (Coleoptera: Chrysomelidae: Bruchinae [ 33 ]), which is also known as the “cowpea weevil”. The granivorous larvae of cowpea weevil are the considerable causative agent of severe losses in the grain germination, weight and nutritional values of chickpea (in some cases reaching 60% of the grain [ 34 ]).…”

Mycotoxins contamination and pest infestation of foods and feeds represent a pivotal threat for food safety and security worldwide, with crucial implications for human and animal health. Controlled atmosphere could be a sustainable strategy to reduce mycotoxins content and counteract the vitality of deleterious organisms in foodstuff. Ozone treatment (O3, 500 ppb for 30, 60 or 90 min) and high nitrogen concentration (N2, 99% for 21 consecutive days) were tested in the post-harvest management of four batches of Cicer arietinum grains to control the presence of mycotoxigenic fungi and their secondary metabolites, as well as pest (i.e., Callosobruchus maculatus) infestation. At the end of the treatment, O3 significantly decreased the incidence of Penicillium spp. (by an average of −50%, independently to the time of exposure) and reduced the patulin and aflatoxins content after 30 min (−85 and −100%, respectively). High N2 concentrations remarkably reduced mycotoxins contamination (by an average of −94%) and induced pest mortality (at 100% after 5 days of exposure). These results confirm the promising potential of O3 and N2 in post-harvest conservation strategies, leading to further investigations to evaluate the effects on the qualitative characteristics of grains.

“…The pre-adult stages of various moth species such as Christoneura rosaceana (Isman and Fitzpatrick, 1995) and Thaumetopoea wilkinsoni (Yilmaz et al 2013), survive better to Bacillus thuringiensis infections when maintained under cooler compared to warmer temperature. However, effects of temperature and fungal infection on life history traits are limited in case of fruit y species but already been explored in case of other insect pests such as earwig larvae (For cula auricularia) (Coulm and Meunier 2021) and granivorous cowpea weevil (Callosobruchus maculatus F.) in stored chickpea (Zahra et al 2023), where temperature considerably affected the population of arthropod pests but higher temperatures favoured more fungi developments. Hence, our study is in corroboration with the earlier studies and is the rst demonstration of dual stress of fungal and temperature under which Z. indianus could thrive where both the factors interact to alter the survival and reproductive potential of the y and gives the possible explanation of invasion of this secondary pest in new ecological niches.…”

Host–pathogens interactions are sensitive to changes in temperature. Increase in temperature significantly influences the distribution of fruit flies. African fig fly, known as Zaprionus indianus (Gupta) (Diptera: Drosophilidae) is one of the invasive, secondary insect pests of fruits. The current article explores the effect of temperature and fungal infection on Z. indianus life history traits. Development of Z. indianus was observed on locally isolated fungus Pichia kudriavzevii (Boidin, Pignal and Besson, 1965) (Saccharomycetales: Pichiaceae) treated and untreated medium. Pre- adult and adult life stages of treated and untreated individuals at different temperatures showed significant difference in trait values and mortality. At extreme temperatures (i.e. 17◦C and 31◦C) the life history traits (egg hatchability, viability, adult emergence, pupation rate and fecundity) in fungi- treated food showed significant reduction in trait values except in development period (egg to adult stage) at 17◦C. High temperatures (28◦C and 31◦C) favour shorter fungal development period but that of Z. indianus was considerably delayed by 5 days at all tested temperatures in treated medium. The current work illustrates the consequences of temperature and fungal infection on the developmental stages and physiological traits of Z. indianus. The combination of the biotic and abiotic factors aids in understanding of the response of pest species of Drosophila to differential temperature ranges and fungal infection; hence, the present study could assist in predicting the driving ecological factors that mediate the containment of Z. indianus, an invasive secondary pest of India.
