Traditional chemical control methods may pose environmental risks and can contribute to resistance development, making alternative strategies such as the implementation of biological control organisms (BCOs) essential. This study presents a meta-analysis evaluating factors that influence the success of BCOs against Phytophthora root rot in annual crops. Systematic data collection and statistical analyses of 49 studies comprising 355 BCO treatments resulted in key insights into the most effective BCO application methods. Root and soil treatments were significantly more effective than seed treatments. Co-application of BCOs with pathogen inoculation enhanced efficacy, likely due to direct antagonism, particularly when specialized metabolites were delivered alongside bacterial BCOs. Strikingly, greenhouse and field trials demonstrated higher BCO efficacy than growth chamber experiments, emphasizing the importance of trial environments. Factor Analysis of Mixed Data (FAMD) and Hierarchical Clustering on Principal Components (HCPC) identified distinct clusters of BCO treatments, revealing clear associations between BCO application methods and efficacy. These findings highlight the need for optimized application methods and formulations to maximize BCO stability and efficacy, potentially enhancing their role in integrated pest management strategies.</div></div>","PeriodicalId":8880,"journal":{"name":"Biological Control","volume":"207 ","pages":"Article 105834"},"PeriodicalIF":3.7,"publicationDate":"2025-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144562930","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, there are also factors frustrating implementation of ABC of which the most important are the lobbying activities of the synthetic pesticide industry and lack of application of the true cost principle for these pesticides which makes them unrealistically cheap.

To address the lack of research-based best practice recommendations for this crop, we compared releases of different lacewing species (<em>Chrysoperla rufilabris</em>, <em>C. plorabunda</em>, <em>C. carnea</em>), life stages (eggs versus larvae), and release methods (sprinkling by hand, egg cards, drone dispersal) for aphid suppression and lacewing survival. Pest and intraguild prey consumption in the field was examined with molecular gut content analysis, using both universal and species-specific primers. In 2021, one hand release of <em>C. plorabunda</em> eggs or <em>C. rufilabris</em> larvae reduced aphid populations by ∼50 % compared to the control, but a release of <em>C. carnea</em> larvae or <em>C. rufilabris</em> eggs did not. In 2022–2023, none of the release treatments decreased aphid abundance, likely because initial aphid numbers were much higher. Recovery of released lacewings was also low in 2023, potentially due to pesticide applications. The highest lacewing larvae recapture rates occurred in the egg card and hand-released larvae treatments; larvae recaptured from these treatments also more frequently tested positive for pest aphid DNA. We found no evidence that lacewing larvae consume other orchard predators. Our initial results indicate that lacewing releases may substantially reduce aphid abundance, but release efficacy is highly dependent on release method, life stage, and timing. Early season releases at the first sign of aphids appear to be particularly critical for success.</div></div>","PeriodicalId":8880,"journal":{"name":"Biological Control","volume":"208 ","pages":"Article 105833"},"PeriodicalIF":3.7,"publicationDate":"2025-06-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144614745","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The developmental time, longevity, reproductive rate, and functional response of <em>O. utetheisae</em> attacking <em>R. pedestris</em> eggs were measured. The influence of parasitism by <em>O. utetheisae</em> females of different ages was assessed for <em>R. pedestris</em> eggs of different ages. In addition, rate of parasitism of <em>R. pedestris</em> eggs by <em>O. utetheisae</em> was evaluated in field-caged experiments. The developmental time of immature parasitoids (from egg to adult emergence) and adult female parasitoid longevity were longer than that of males. The average lifetime fecundity per female of <em>O. utetheisae</em> was 56.9 eggs, and the progeny sex ratio was 86.8% female. On average, 2.6 wasps emerged from each <em>R. pedestris</em> egg. The functional response of the parasitoid followed Holling’s Type III model, with a theoretical maximum daily parasitism rate of 14.9 eggs at an optimal host density per day. Parasitism was greater than 90% for 1–8 − day old <em>O. utetheisae</em> females attacking 1–3 − day old <em>R. pedestris</em> eggs.

However, the impacts of LEDs on the life cycle of beneficial predators remain insufficiently explored. This study examined the mating behaviors and developmental performance of generalist predator <em>Orius insidiosus</em> under light spectra previously shown to support its predation of the pest thrips <em>Frankliniella occidentalis</em>. In laboratory experiments, predator pairs were exposed to artificial light sequences starting with a 12 h baseline solar light condition simulating a cloudy winter day, supplemented by 8 h photoperiod extensions (blue, blue-red, or blue-green–red spectra), or a control without extension. Mating occurred under all tested conditions, but blue light reduced mating frequency and duration. Photoperiod extension improved fecundity, fertility, and resulted in the highest number of second-generation <em>O. insidiosus</em> adults, with blue light favoring egg laying and hatching but not metamorphosis into adults. The second-generation sex ratio was unaffected by light sequence, maintaining population viability with a balanced proportion of females.

In particular, establishment has not been confirmed in hot, southern Texas locations despite release of over 150,000 thrips across four locations since 2022. To understand whether thermal limitations may preclude use of <em>P</em>. <em>ichini</em> in some regions, we investigated upper and lower thermal limits of <em>P. ichini.</em> We measured upper limit of chill injury zone (ULCIZ) and lower limit of thermal injury zone (LLTIZ) in the laboratory under multiple combinations of temperature and exposure duration then modeled spatial variation in survival based on detailed weather data over 20 years. Additionally, we documented microhabitat variation in temperature extremes in three release sites in south Texas to evaluate whether thermal refugia exist due to variation in microhabitat conditions. Based on LLTIZ and ULCIZ, thermal injury accumulates rapidly at temperatures above 33.08 ± 0.15 °C and more slowly at decreasing temperatures below 7.85 ± 0.82 °C. Temperatures within the canopy of <em>S. terebinthifolia</em> in the field varied widely and produced a range of predicted mortality, with temperatures at the base of trees that were more moderate in both summer and winter. We determined that, based on the current distribution of <em>S. terebinthifolia</em> in the USA, climate suitability differs between states. Suitability of Florida locations was deemed highly to moderately suitable across seasons, but most Texas locations were unsuitable, including previous release locations in south Texas. These findings suggest releases should continue through most of Florida, in areas of southern California, and locations along the northern gulf coast of Texas.
