“…The morphological characters of T. remus evaluated in our study (wing length, wing width, body length, and right hind length) were not reduced from generation P 35 to generation P 45 . Moreover, our results (from generation P 35 to P 45 ) are similar to previous results reported by Pomari-Fernandes et al (2016) for generations P 1 to P 19 . More importantly, T. remus reared on C. cephalonica for 45 generations (P 45 ) had the same percentage of ‘flyers’ than the parasitoid reared on the natural host, S. frugiperda .…”

“…More importantly, T. remus reared on C. cephalonica for 45 generations (P 45 ) had the same percentage of ‘flyers’ than the parasitoid reared on the natural host, S. frugiperda . Our results suggest that the dispersal capacity of smaller T. remus reared on C. cephalonica eggs was not impaired, similar to that of individuals from earlier generations (Pomari-Fernandes et al , 2016).…”

“…Although wing length, wing width, body length, and right hind length of T. remus were previously examined for parasitoids reared successively on C. cephalonica eggs, this was only done for 19 generations (Pomari-Fernandes et al , 2016). The authors reported smaller values for morphological characters of parasitoids reared on C. cephalonica eggs compared with parasitoids reared on S. frugiperda eggs.…”

“…Although smaller, they showed the same flight activity (percentage of ‘flyers’, ‘walkers’, and ‘deformed’) as bigger T. remus individuals reared on S. frugiperda eggs, indicating that a reduction of parasitoid size on the factitious host does not reduce its dispersal capacity, and is therefore adequate for biological control purposes. However, Pomari-Fernandes et al (2016) studied neither those morphological characters nor the flight activity of more advanced generations of T. remus reared in the factitious host. It is crucial to understand whether successive T. remus rearing on C. cephalonica eggs for longer periods impairs parasitoid fitness over time.…”

Egg parasitoid rearing on factitious hosts is an important step to reduce costs and increase availability of the biocontrol agent but it requires quality control to achieve success in field conditions. To this end, this study evaluated the quality of Telenomus remus (Hymenoptera: Platygastridae) reared on Corcyra cephalonica (Lepidoptera: Pyralidae) for until 45 generations. In the first bioassay, we evaluated the body size of the laboratory-produced parasitoids. In the second bioassay, flight activity was examined, measuring the percentage of 'flyers', 'walkers' and 'deformed' parasitoids. The third bioassay assessed parasitism on Spodoptera frugiperda (Lepidoptera: Noctuidae) eggs. Our data indicate that the laboratory-reared parasitoid neither lost its ability to fly nor to parasitize S. frugiperda eggs. In conclusion, quality did not decrease significantly during 45 generations, and therefore rearing of T. remus on C. cephalonica as factitious host promises to be successful.

“…T. remus can also survive climates of the subtropical dry forests of Southern Europe in the event of global warming (RCP6.0 and 8.5). Almost all rainforests in Latin America will become suitable with increased temperature regimes as the climate changes (RCP6.0 and 8.5) 45,46 . The habitat suitability of T. pretiosum almost mirrors that of the first egg parasitoid T. remus , except that southern parts of North America are suitable and southeastern Asia is unsuitable for the former.…”

BACKGROUND The southern armyworm (SAW) Spodoptera eridania (Stoll) (Lepidoptera: Noctuidae) is native to the tropical Americas where the pest can feed on more than 100 plant species. SAW was recently detected in West and Central Africa, feeding on various crops including cassava, cotton, amaranth and tomato. The current work was carried out to predict the potential spatial distribution of SAW and four of its co‐evolved parasitoids at a global scale using the maximum entropy (Maxent) algorithm. RESULTS SAW may not be a huge problem outside its native range (the Americas) for the time being, but may compromise crop yields in specific hotspots in coming years. The analysis of its potential distribution anticipates that the pest might easily migrate east and south from Cameroon and Gabon. CONCLUSION The models used generally demonstrate that all the parasitoids considered are good candidates for the biological control of SAW globally, except they will not be able to establish in specific climates. The current paper discusses the potential role of biological control using parasitoids as a crucial component of a durable climate‐smart integrated management of SAW to support decision making in Africa and in other regions of bioclimatic suitability. © 2021 The Authors.

BACKGROUND Telenomus remus (Nixon) is a dominant natural enemy controlling the invasive pest Spodoptera frugiperda (J. E. Smith). Continuous rearing of egg parasitoids on alternative hosts is crucial for mass production and cost reduction. However, to ensure the effectiveness of natural enemy products against target pests in the field, it is necessary to evaluate the parasitoid quality during the mass‐rearing process. Despite the successful rearing of this parasitoid on the alternative host Spodoptera litura (Fabricius) eggs, less attention has been paid to the quality of parasitoids continuously reared for multiple generations. Therefore, we evaluated the performance of T. remus reared on S. litura eggs for 30 generations via morphological characteristics, flight ability, and life table analysis. RESULTS Wing length, wing width, body length, and right hind tibia length of T. remus did not differ among the different generations. However, the body length of female parasitoids was significantly longer than that of males for any generation. Although the proportion of ‘flyers’ and ‘deformed’ T. remus varied among generations, the flight ability did not decline significantly after rearing on S. litura eggs. Moreover, T. remus continuously reared on S. litura eggs maintained stable parasitism performance and life table parameters on the target host S. frugiperda eggs. CONCLUSION S. litura eggs are suitable hosts for the mass‐rearing of T. remus. This study can be subsequently used to guide the production and facilitate the application of T. remus in the control of S. frugiperda. © 2023 Society of Chemical Industry.
