Therefore, this study aimed to gather information of insecticide resistance development, cross-resistance pattern, and inheritance mode of resistance to clothianidin and triazophos in laboratory selected strains of <em>O</em>. <em>hyalinipennis</em>. The results showed that after 9 generations, resistant strains developed high levels of resistance to clothianidin (640.97-fold for Clothi-RS3, 1204.06-fold for Clothi-RS2, and 2472.52-fold for Clothi-RS1) and triazophos (236.38-fold for Triaz-RS3, 299.53-fold for Triaz-RS2, and 714.15-fold for Triaz-RS1) compared to the susceptible strains. The extremely high cross-resistance to triazophos (158.42-fold), profenofos (1128.32-fold) and indoxacarb (387.10-fold) in the Clothi-RS1 strain, compared to the respective susceptible strain was observed. Similarly, extremely high cross-resistance to clothianidin (255.90-fold), profenofos (451.33-fold) and indoxacarb (954.79-fold) in the Triaz-RS1 strain was observed. Overlapping 95 % confidence limits of LC_50s of all reciprocal crosses and degree of dominance values revealed an autosomal and incompletely dominant resistance to clothianidin and triazophos. All backcrosses of the F₁ reciprocal cross with resistant parent strains predicted a polygenic inheritance. In conclusion, clothianidin and triazophos resistance was inherited as autosomal, incompletely dominant, and polygenic in the Cloth-RS and Triaz-RS. The high level of cross-resistance to clothianidin, triazophos, profenofos, and indoxacarb indicates that these pesticides are ineffective in controlling the target pest.

Copper-based fungicides are widely used in viticulture to manage fungal diseases, but may also impact non-target insect pests. This study investigated the effects of Bordeaux mixture on the oviposition behavior and egg survival of the grapevine pest <em>Lobesia botrana</em>, under simulated current (2002–2021) and future (2081–2100) climatic scenarios. Laboratory choice and no-choice experiments were conducted to assess oviposition preferences, potential deterrent effects of Bordeaux mixture, and its toxicity to eggs. In the choice experiment, <em>L. botrana</em> females showed significant preference for untreated grapes under both climatic conditions. However, in the no-choice experiment, Bordeaux mixture neither significantly deterred oviposition nor affected egg hatching rate in either scenario. While Bordeaux mixture had minimal influence on oviposition behavior, future climatic conditions significantly reduced female longevity and fecundity. This reduction in reproductive output may suggest lower pest pressure, but accelerated generation turnover and increased voltinism under warmer conditions could amplify pest pressure in the long term. This study provides insights on the collateral effects of Bordeaux mixture on <em>L. botrana</em> under a future climatic scenario and emphasizes the need for further research on its potential impacts on other key life history traits (e.g., development, reproduction).

It has been validated for other important citrus pests such as <em>Aonidiella aurantii</em> and <em>Tetranychus urticae</em> but not for aphids. In this work, the <em>Proof-CitrusVol</em> version was evaluated by comparing the aphid control efficacy of applications adjusted using the tool versus conventional higher-volume applications. Based on insufficient aphid control during the initial year of field testing, the tool was modified, and a new version was subsequently validated. The field trial results showed that <em>CitrusVol</em> reduced the spray volume by 29% on average without affecting control efficacy compared with conventional applications. Consequently, <em>CitrusVol</em> reduced the operational time by 16 h/100 ha per application because of fewer refills of the sprayer tank.
