Abstract Root-knot nematodes cause global economic losses in a wide range of crops. We investigated the potential of seed coatings of the cover crop Phacelia tanacetifolia (Boraginaceae) when inoculated with the nematophagous fungus Pochonia chlamydosporia (Hypocreales: Clavicipitaceae) to protect subsequently grown tomato plants from root galling caused by the root-knot nematode Meloidogyne hapla (Tylenchida: Meloidogynidae). Therefore, seeds of P. tanacetifolia were coated with P. chlamydosporia blastospores and planted in M. hapla -infested pots. After 50 days of growth in infested soil, M. hapla eggs were extracted from P. tanacetifolia roots and quantified. Tomato plants grown in the remaining soil served as bioindicator of M. hapla infestation as expressed by the gall index. Results showed that seed coating of P. tanacetifolia with P. chlamydosporia (290 ± 51 CFU per seed) reduced the number of M. hapla eggs up to 95.6% in comparison to untreated controls. Pochonia chlamydosporia as blastospore suspension (5·10 8 blastospores per 600 ml soil) reduced the number of M. hapla eggs by up to 75.5%. Additionally, tomato plants grown for 50 days in substrates previously planted with P. tanacetifolia seeds coated with P. chlamydosporia showed a significantly lower gall index than plants grown in untreated pots. In conclusion, biological enhancement of P. tanacetifolia by seed coating with P. chlamydosporia successfully reduced M. hapla and thus provides an additional tool in the management of this nematode. The method still has potential for further improvement such as increasing blastospore viability within the seed coating by optimized formulation technology.

Abstract Several spiny leguminous tree species within the genus Neltuma Raf. (formerly Prosopis L.) (Fabaceae) occur as widespread invasive alien plants in South Africa, exerting severe negative socio-economic and ecological impacts. Given these impacts, South Africa recently released the leaf-tying moth Agnippe sp. #1 (syn. Evippe sp. #1) (Lepidoptera: Gelechiidae) as a biological control agent against invasive Neltuma species in 2021. The widespread invasion of Neltuma spp. across a vast and climatically diverse range of South Africa has led to concerns regarding the establishment and impact of the agent. Therefore, this study aimed to assess the constraints posed by climate to the potential establishment and efficacy of Agnippe sp. #1 using both climatic matching (CLIMEX) and thermal-physiology assessments. Climatic analyses revealed relatively high (71%) and moderate (66%) matches of South Africa to the native (Argentina) and introduced (Australia) ranges of Agnippe sp. #1 respectively. Thermal assessments of Agnippe sp. #1, particularly the 4 th instar larvae, determined a CT min = 0.9 ± 0.3 °C and LLT 50 = −11.1 ± 0.4 °C, which suggest the moth is suited mainly to warmer regions of South Africa. Overall, these assessments propose that the establishment and performance of Agnippe sp. #1 is likely to be constrained by climate in parts of South Africa, particularly within the cold semi-arid and temperate provinces of the country. Promisingly, these climatic comparisons suggest that Agnippe sp. #1 may become more widely established in the hottest parts of the Northern Cape province, which remains a major biological control target region for Mesquite in South Africa.

Abstract Classical biological control (CBC) has been exploited as a safer alternative for suppressing the oriental fruit fly, Bactrocera dorsalis, by importing, rearing, and releasing the larval parasitoid, Diachasmimorpha longicaudata . Although D. longicaudata has been released in Kenya through the Africa Fruit Fly Programme, the extent of its dispersal and subsequent economic benefits have not yet been established. This paper models the spatio-temporal dispersal of the parasitoid using the fuzzy cellular automata approaches and estimates the net benefit from each dollar invested in the CBC approach. We calculated the return on investment based on funding into the programme between 2006 and 2015 and the result of the dispersal range of the parasitoid predicted using an artificial intelligence algorithm. The investment yielded a significant net present value of US$42.8 million over the 16 years. Besides, the cost–benefit ratio showed that for every US$1 invested, the return benefit was US$93 , confirming the profitability of the CBC program. The economic gains are significant considering that there is no environmental contamination and possible adverse effects from the CBC intervention. The study findings support investment in biological control strategies for the eco-friendly and area-wide management of B. dorsalis.

Abstract Fly infestations threaten farming and livestock operations, contributing to animal irritation and the spread of serious diseases. In this study, the application of Bacillus velezensis PHP1601 (Bacillales: Bacillaceae) treatments (10 5 and 10 10 endospore g −1 ) to pig manure slurries was evaluated as a means of controlling fly reproductive cycles. Two cycles of fly emergence were evaluated over a 33 days period for each replicated trial. For both treatments, the first emergence event resulted in a significant reduction in the percentage of flies emerging compared to an un-treated control. Extended monitoring of the biocontrol containers revealed that fly emergence was completely eliminated by the time that a second round of fly emergence was observed for the control. A B. velezensis -specific real-time PCR method was developed and used to assess the population dynamics of the applied biocontrol agent over the course of the experiment. Strain PHP1601 remained viable in the manure and cell numbers increased by several orders of magnitude. REP-PCR fingerprinting was used to confirm the clonality of endospores recovered from the manure. Fly species recovered from the trials were identified by cytochrome oxidase gene barcode sequencing. Several species of veterinary and medically significant flies were identified. They were all deemed to be susceptible to treatments with PHP1601 and constituted part of the strain's host range. The study demonstrated the effectiveness of B. velezensis PHP1601 as a promising biocontrol agent for controlling fly infestations under conditions similar to its intended use.
