“…The lack of spatial genetic structure at varying geographic levels has implications for pest management. Physiological and behavioral differences among populations of the maize weevil have been reported and such differences incur in likely differences in dispersion and damage potential to the host grains (Morales et al , 2013; Carvalho et al , 2014; Malia et al , 2016). However, such differences seem more prevalent within populations rather than between populations, suggesting a high multidirectional gene flow, which is consistent with the findings we reported herein and with recent studies using sets of integrated behavioral tendencies in populations of the maize weevil (Morales et al , 2013; Malia et al , 2016).…”

Archeological records attest the early association of Sitophilus with stored cereals from the beginning of agriculture on Asia. The maize weevil (Sitophilus zeamais) became particularly damaging to maize, a cereal crop domesticated on Mesoamerica. We investigated the late evolutionary history of the maize weevil to gain insights on its origin, timing of association with maize, and genealogical relationship to the almost morphologically indistinguishable rice weevil (Sitophilus oryzae). Two mitochondrial genes (cytochrome oxidase subunit I and cytochrome oxidase subunit II) and the nuclear ribosomal gene region were partially sequenced. Analyses showed that the maize weevil shared no haplotypes with the rice weevil; instead, each species exhibited distinct mitogroups and ribogroups. The two weevil species likely split about 8.7 million years ago (95% highest posterior density: 4.0-15.0). Microsatellite data analyses sorted the 309 specimens from 15 populations of the maize weevil into three genotypic groups, which displayed low genetic differentiation and widespread occurrence worldwide. The maize weevil and the rice weevil are each a distinct species; both of which emerged prior to the onset of agriculture. The maize-maize weevil association took place after maize became widespread as a global crop. The maize weevil populations lack spatial genetic structure at the regional, continental, and intercontinental scales.

“…This could explain this heterogeneity. Another possible explanation is the differences in dehydration among individuals may interpret this gained heterogeneity (Malia et al, 2016b). However, several pesticide studies on stored-product insects have been confirmed this heterogeneity response (Sehgal et al, 2013;Subramanyam et al, 2014;Tadesse et al, 2019).…”

Globally, there are growing concerns about the overuse of synthetic insecticides to their subsequent damage to the environment and mammalian. Therefore, developing new and safe eco-friendly insecticides based on natural products, such as essential oils,is considered a substitute for chemical pesticides in pest control. In the present study,mimicry the storage environment for grain products stored in a small scale by surface treatment method to determining the lethal and effective concentrations for three chemical insecticides (Imidacloprid, Zeta-cypermethrin and Lufenuron) and three essential oils (Citrus bergamia, Citrus limon and Cuminum cyminum) against larvae of Trogoderma granarium at various concentrations and time intervals. Results revealed that the C. bergamia EO exhibited high larvacidal activity compared to the other two oils, i.e.,30.36% after 24h of exposure at the higher concentration (10 v/v), while after 72h of exposure at the same,mortality reached 75.33%. Concerning chemical insecticides, the imidacloprid insecticides at all tested concentrations were the most effective against T. granarium larvae, leading to 40% mortality at the lower concentration (1v/v) after 24h. of exposure, and 96.66% mortality at the higher concentration(10 v/v)72h. post-exposure. Whereupon, C. limon oil had significantly higher LC50 and LC99 values than other oils, indicating that C. bergamia oil was more toxic against T. granarium larvae than to both oils. In contrast, LC99 values of Lufenuron were the highest significantly being about 1.61 and 2.31 times compared to Zeta-cypermethrin and Imidacloprid at the maximum concentration tested after 72h of exposure, respectively.In sum,our research focuses on the potential of selected EOs as a suitable substitute for chemical pesticides against this noxious species.

“…Studying the plasticity of insects’ behavioural response to environmental challenge has raised considerable interest in entomology (Juliano, Olson, Murrell, & Hatle, ; Liefting, Hoffmann, & Ellers, ), and there is now an increasing focus on individual differences in behaviour that are repeatable across situations coined “personality” (Guedes et al, ; Kralj‐Fišer & Schuett, ; Tremmel & Müller, ). Difference in personality between genotypes is particularly relevant to support the persistence of genetic diversity within and among insect population, which was found to be a potential driver of behavioural resistance (Malia, Rosi‐Denadai, Cardoso, & Guedes, ; Morales, Cardoso, Della Lucia, & Guedes, ). Personality consolidation occurring when positive selection favours correlation between multiple behavioural traits promoting the emergence of discrete “behavioural syndromes” which help support ecological functions (Chapman, Thain, Coughlin, & Hughes, ; Jandt et al, ).…”

Sublethal larval exposure to imidacloprid impacts adult behaviour in Drosophila melanogaster

Pesticides are now chronically found in numerous ecosystems incurring widespread toxic effects on multiple organisms. For insects, the larvae are very exposed to pesticide pollution and the acute effect of insecticides on larvae has been characterized in a range of species. However, the carry‐on effects in adults of sublethal exposure occurring in larvae are not well characterized. Here, we use a collection of strains of Drosophila melanogaster differing in their larval resistance to a commonly used insecticide, imidacloprid, and we test the effect of larval exposure on behavioural traits at the adult stage. Focusing on locomotor activity and on courtship and mating behaviour, we observed a significant carry‐on effect of imidacloprid exposure. The heritability of activity traits measured in flies exposed to imidacloprid was higher than measured in controls and in these, courtship traits were genetically less correlated from mating success. Altogether, we did not observe a significant effect of the larval insecticide resistance status on adult behavioural traits, suggesting that selection for resistance in larvae does not involve repeatable behavioural changes in adults. This lack of correlation between larval resistance and adult behaviour also suggests that resistance at the larval stage does not necessarily result in increased behavioural resilience at a later life stage. These findings imply that selection for resistance in larvae as well as for behavioural resilience to sublethal exposure in adult will combine and impose a greater evolutionary constraint. Our conclusions further substantiate the need to encompass multiple trait measures and life stages in toxicological assays to properly assess the environmental impact of pesticides.
