A thrips, <em>Pseudophilothrips ichini</em>, is being mass produced and released as an approved agent for biological control of this invasive weed. The <em>P. ichini</em> thrips are flush feeders, especially the larvae, that exploit seasonal new plant growth. Adult <em>P. ichini</em> thrips selected pruned, re-flushing Brazilian peppertree plants, and produced 4-fold more F₁ thrips than those that chose unpruned, non-flushing plants. To determine if pruning increased the abundance of foliar flush production, field populations of Brazilian peppertree in the invaded range were pruned every 3 months for 14 months. The pruned Brazilian peppertree plants produced more flush leaves, that continued to be produced for longer periods, compared with seasonal unpruned plants. Following pruning, re-flushed Brazilian peppertree leaves had greater percent moisture (65.0 % vs 60.0 %) and nitrogen (1.6 % vs 1.3 %) compared with non-flushing leaves. The levels of several terpenoid constituents trended higher in the re-flushed leaves compared with the non-flushing leaves including Germacrene D, Caryophyllene, Bicyclogermacrene, and Sabinene. These results suggest that routine pruning of Brazilian pepper plants at field sites can improve plant quality and may increase the production of thrips. This management approach can be implemented at field nurseries for the mass production of agents.</p></div>","PeriodicalId":8880,"journal":{"name":"Biological Control","volume":"195 ","pages":"Article 105550"},"PeriodicalIF":4.2,"publicationDate":"2024-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S1049964424001154/pdfft?md5=bafa9843b55f0e7c579e35d722a7673d&pid=1-s2.0-S1049964424001154-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141312880","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, despite modelling and mesocosm experiments, field studies are scarce, and we know nothing of its temporal dynamics within real-world food webs, particularly in the context of biological control. To address this, we added manure to cereal fields to increase decomposer prey, and analysed the diet of over 6000 predators over the entire cropping season during two consecutive years. Our results show that manure increased available prey temporarily and reduced intraguild predation. With this organic fertilization, a reduction in pest spread between tillers within fields correlated with lower intraguild predation, while pest density remained unchanged across treatments, making the net effect on biological control unclear. We hypothesize that the mechanism responsible for why lowering intraguild predation reduces pest spread are changes in predator behaviour, that allow predators to exert more pressure on pests. Conversely, the absence of an effect on pest density may be linked to other effects of fertilization, such as increased pest and plant growth counteracting any increase in predation pressure. The high temporal resolution of our data showed how dynamic IGP is throughout the season, which stresses the importance of studying food webs over time, to generate a mechanistic understanding of biological control.</p></div>","PeriodicalId":8880,"journal":{"name":"Biological Control","volume":"194 ","pages":"Article 105549"},"PeriodicalIF":4.2,"publicationDate":"2024-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S1049964424001142/pdfft?md5=c2d8d62ae31649cb1c0c93479d9e6f66&pid=1-s2.0-S1049964424001142-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141278571","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As a result, the fungus <em>Metarhizium</em> spp. is used as an alternative control for BPH. However, their efficiency is limited due to delayed infectivity and sensitivity to environmental variables. In this study, two isolates of <em>Metarhizium</em> spp. MLUBN038 and MNMHN031, were induced for thermotolerance and biocontrol potential against <em>Nilapavarta lugens</em> (Stål). A multilocus phylogeny of four protein-coding genes including Beta-tubulin, <em>rpb1</em>, <em>rpb2</em>, and <em>tef</em> has identified the two isolates to be <em>Metarhizium koreanum</em>. Seventy-nine potential thermotolerant mutants were screened from the two isolates. These mutant isolates demonstrated significant tolerance to vegetative heat at 39 °C and enhanced resistance to wet heat stress at 45 °C after exposure for 60 h, outperforming the wild-type (WT) isolates. The mutant isolates also showed increased mycelial growth, conidial germination, and spore production compared to the WT isolates. Two mutant isolates, ML038_Mt 71 and MN031_Mt 46, exhibited the highest efficacy against BPH nymphs (4th-5th instars), resulting in a maximum mortality of 88.82 % and 83.55 %, respectively, compared to the WT (54.07 % and 47.54 %) after 14 days of inoculation in the greenhouse.

Historical weed management consisted of herbicide and mechanical/manual removal. However, due to funding constraints, biological control was implemented as a cost-effective and environmentally friendly alternative. The impoundment receives excessive phosphorus and nitrogen due to its location downstream from densely populated cities, which includes one of the capital cities of South Africa, Pretoria. Considering that Hartbeespoort Dam is in a temperate region, with cool winters, we embarked on an augmentative biological control approach. To increase our biological control efforts, we had to bridge the research-implementation gap. We fostered a community of practice, by creating a space for the affected community to actively participate in the programme. This would give us the opportunity to share scientific knowledge to affected stakeholders, gauge the public perception, and align potential goals. Social media, in-person meetings and training sessions were used to engage with the public. To increase the availability of the water hyacinth biological control agent, <em>Megamelus scutellaris</em>, community members (i.e. private stakeholders) were offered the opportunity to manage satellite rearing stations. Between 2018 and 2023, nearly half a million <em>Megamelus scutellaris</em> individuals, sourced from both the Centre for Biological Control’s mass-rearing facility and satellite rearing stations around Hartbeespoort Dam, have been released into the dam. Water hyacinth cover on the dam drastically declined every year following a build-up of <em>Megamelus scutellaris</em>. Over the course of the programme, private stakeholders that were actively involved grew from two (2018) to 16 (2023). Analysing the participation of private stakeholders using a framework that looks at the level of value gained from our interactions, two partners reached a value chain phase that led to an expansion of biological control implementation. Longer-term private stakeholders generated increased interest for biological control implementation in their community, which resulted in recruitment of new private stakeholders. We also evaluated the knowledge of the affected community in 2023 through an online questionnaire. Out of 132 respondents, 51 % had knowledge of what biological control entails, with 56 % acknowledging that biological control has had a positive impact on the management of water hyacinth. Bridging the research-implementation boundary has strengthened biological control efforts, enabling a more sustainable approach to the management of water hyacinth on Hartbeespoort Dam.
