The specific threshold of the initial population size necessary for the successful establishment of an invasive species remains uncertain. This research delves into the effects of different initial population sizes on the colonisation and population dynamics of the globally recognised invasive pest, <i>Cydia pomonella</i>, within a controlled laboratory setting. The results revealed that even a single pair of <i>C. pomonella</i> displayed notable eggs laid (fecundity) and hatched (fertility) by producing offspring upon mating. Larger initial population size exhibited increased mating rates, leading to enhanced fecundity and subsequently more offspring, indicating that the development of <i>C. pomonella</i> population is directly impacted by the mating rate of the initial individuals. Projections based on <i>F</i>₁ data indicate that the <i>C. pomonella</i> population size could persistently increase over a span of 150 days, with varying growth rates influenced by the initial population size. These findings indicate the importance of heightened monitoring and management in non-invaded regions to avert early colonisation of <i>C. pomonella</i>, thus mitigating the threat of invasion and subsequent population expansion.</p>\u0000 </div>","PeriodicalId":14987,"journal":{"name":"Journal of Applied Entomology","volume":"149 2","pages":"157-164"},"PeriodicalIF":1.7,"publicationDate":"2024-11-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143475548","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As the resistance of whiteflies to chemical insecticides is increasing, this study aimed to investigate the potential of entomopathogenic fungi as an alternative. A total of 72 entomopathogenic fungal isolates, collected from soils using <i>Tenebrio molitor</i> larvae as an insect baiting method, were assessed for their virulence against 2nd nymphs of whitefly. Their virulence was assayed by dipping whitefly-infested tomato leaves in fungal conidia suspensions at 1.0 × 10⁷ conidia/mL. Among the tested isolates, two isolates of <i>Beauveria bassiana</i> JEF-462 and JEF-507 showed high virulence. In the assessment of virulence depending on conidia concentrations, the estimated LC₅₀ values for JEF-462 and JEF-507 were similarly 8.7–14.0 × 10⁷ conidia/mL. However, <i>B. bassiana</i> JEF-507 showed higher conidial productivity and thermotolerance on most of tested 12 grain substrates than <i>B. bassiana</i> JEF-462, and millet was the most suitable grain substrate. Additionally, siloxane as a surfactant was able to sufficiently exhibit the insecticidal activity of JEF-507 against whitefly nymphs compared with other surfactants. In a pot-based greenhouse trial, JEF-507 showed higher control efficacy than chemical insecticides, dinotefuran and spinetoram. This work suggests that <i>B. bassiana</i> JEF-507 could be competitively used as a biopesticide to control silverleaf whiteflies while overcoming current resistance issues.

We analysed aphid acceptance rate, population growth, and load under different wheat treatments. Additionally, we characterised wheat aboveground biomass and nitrogen content as important functional traits for aphid resistant. Aphid acceptance decreased in plants of cv. Forment when exposed to volatiles from undamaged Florence-Aurora plants, whereas the other tested combinations tested had no effect. Aphids performed differently in the two mixtures: Florence-Aurora mixed with Forment significantly reduced aphid population growth and load compared to the monocultures, whereas the combination of Florence-Aurora with Montcada wheat had no effect on aphid performance. The plant–plant interactions also modified the analysed traits. Nitrogen content of Florence-Aurora wheat plants was reduced when mixed with Forment wheat, which may explain the lower aphid load observed in plants of cv. Florence-Aurora when mixed with plants of cv. Forment. However, mixing wheats with similar aboveground biomass resulted in an increase in the average biomass of plants of both cultivars which could have led to a higher aphid population. The data supports the idea of right neighbour, as the benefits of wheat mixtures for aphid control were determined by the identity of the combined plants (or species).

Therefore, we exposed honey bee workers to a field-realistic oral dose of clothianidin for 7 days to assess their sugar responsiveness, and olfactory learning and memory using the proboscis extension response paradigm. Sugar responsiveness impacts important colony-level traits, such as onset of foraging, that help maintain colony homeostasis as well as impacts learning and memory.

We identified 5069 protein groups and showed that the exposed bees had fewer detectable proteins.

Sampling corn fields to determine the <i>D. maidis</i> density for decision-making systems can be challenging due to field size, time and cost.
