Abstract:
Macrotermes termites play important ecological roles and are consumed by many communities as a delicacy and dietary complement throughout Africa. However, lack of reliable morphological characters has hampered studies of Macrotermes diversity in a wide range of scientific fields including ecology, phylogenetics and food science. In order to place our preliminary assessment of the diversity of Macrotermes in South Africa in context, we analysed a comprehensive dataset of COI sequences for African species including new and publicly available data. Phylogenetic reconstruction and estimates of genetic divergence showed a high level of incongruity between species names and genetic groups, as well as several instances of cryptic diversity. We identified three main clades and 17 genetic groups in the dataset. We propose that this structure be used as a background for future surveys of Macrotermes diversity in Africa, thus mitigating the negative impact of the present taxonomic uncertainties in the genus. The new specimens collected in Limpopo fell into four distinct genetic groups, suggesting that the region harbours remarkable Macrotermes diversity relative to other African regions surveyed in previous studies. This work shows that African Macrotermes have been understudied across the continent, and that the genus contains cryptic diversity undetectable by classic taxonomy. Furthermore, these results may inform future taxonomic revisions in Macrotermes, thus contributing to advances in termitology.

Abstract:
Several studies have demonstrated the biological efficacy of leaf, stem and root powders or extracts of Chromolaena odorata (L.) King and Robinson against insect pests but those that are focused on the biological efficacy of aqueous leaf extracts against Macrotermes species are scanty. Current management of termites with synthetic insecticides is being discouraged due to human and environmental hazards. Therefore, the insecticidal effectiveness of aqueous leaf extract C. odorata against Macrotermes species was investigated. Five concentrations (0, 2.5, 5.0, 7.5 and 10.0% (w/v)) of the aqueous extract of C. odorata plant were evaluated for repellency and toxicity on the worker caste of Macrotermes species following standard procedures. The filter paper impregnation technique was used for the bioassay. Percentage repellency was monitored for 30 minutes and mortality recorded at 12, 24 and 36 hours post exposure. The leaf extract of C. odorata significantly repelled 95% of Macrotermes species at the highest concentration of 10% (w/v) after 30 minutes post treatment exposure. Mortality of Macrotermes species was independent of treatment concentration, but dependent on duration of exposure. All treatment concentrations of aqueous leaf extract of C. odorata caused significant mortality against Macrotermes species ranging between 94% and 98% compared to the control; indicating very great potential for adoption and use in the management of Macrotermes species.

Abstract:
Brachytrupes membranaceus and Macrotermes subhyalinus are edible insects in Burkina Faso. Our research aimed to evaluate the nutritional composition and functional properties of the defatted flours, protein concentrates, and isolates of Brachytrupes membranaceus and Macrotermes subhyalinus. Proximate and mineral composition were determined according to AOAC methods. The amino acid and fatty acid composition were determined by high-performance liquid chromatography (HPLC) and gas chromatography, respectively. The protein concentrates and isolates were obtained by solubilization, precipitation, and lyophilization. Macrotermes subhyalinus showed the highest protein (45.75 g/100 g), iron (11.76 mg/100 g), and zinc (13.18 mg/100 g) contents. The highest isoleucine and lysine contents, the best fat absorption (10.87 g/g), and foaming capacities (49.60%) were obtained with the isolate of Brachytrupes membranaceus. Consumption of Macrotermes subhyalinus could be used to fight or correct iron and zinc deficiencies. Macrotermes subhyalinus was a source of macronutrients and micronutrients, while the protein concentrates and isolates of Brachytrupes membranaceus were endowed with functional properties (fat absorption and foaming capacities).

Abstract:
En Afrique de l’Ouest, les termites sont communément utilisés comme alimentation protéinique pour la volaille. Cette étude avait pour objectif de tester et d’améliorer une méthode traditionnelle de collecte des termites par piégeage avec un récipient renversé, au Nord du Burkina Faso. Des essais ont été menés avec deux genres de termites (Macrotermes et Odontotermes) afin d’évaluer l’effet des saisons, des substrats, des récipients et de l’exposition au soleil sur leur piégeage. Six substrats ont été utilisés avec trois types de récipients (en terre cuite, en fer et en plastique) pour collecter les termites. Les résultats ont montré que le canari en terre cuite est le meilleur récipient pour la collecte des termites. Les meilleurs substrats pour capturer les Macrotermes, ont été les substrats contenant des tiges de sorgho et, pour les Odontotermes, les substrats contenant la bouse de vache. L’exposition des pièges au soleil a eu un effet négatif significatif sur les Odontotermes, mais pas sur les Macrotermes. Ces résultats peuvent aider les aviculteurs à améliorer le piégeage des termites en utilisant le récipient et les substrats les plus adéquats et en protégeant leur piège du soleil.Mots clés : Termites, aliments pour volaille, Macrotermes, Odontotermes, Burkina Faso. English Title: Evaluation of termite trapping methods in northern Burkina Faso In West Africa, termites are commonly used as a protein feed for poultry. The objective of this study was to test and improve a traditional method of trapping termites with an overturned container in northern Burkina Faso. Trials have been conducted with two termite genera (Macrotermes and Odontotermes) to assess the effect of seasons, substrates, containers and sun exposure on their trapping. Six substrates were used with three types of containers (terracotta, iron and plastic) to collect termites. The results showed that the terracotta container is the best container for collecting termites. The best substrates for Macrotermes were the substrates containing sorghum stalks and, for Odontotermes, the substrates containing cow dung. Exposure of the traps to the sun had a significant negative effect on Odontotermes, but not on Macrotermes. These results can help poultry farmers improve termite trapping by using the most suitable container and substrates and protecting their trap from the sun.Keywords: Termites, poultry feed, Macrotermes, Odontotermes, Burkina Faso.

Abstract:
Eocorythoderus incredibilis, a new genus and new species, of Corythoderini is described. This new species was found infungus gardens of Macrotermes gilvus (Hagen, 1858) in Angkor Wat, Cambodia. The new taxon is a flightless, mi-crophthalmic species and the first corythoderine associated with Macrotermes Holmgren, 1910. The beetles were ob-served being carried by worker termites. Eocorythoderus is probably closely related to the genera Corythoderus Klug,1845 and Paracorythoderus Wasmann, 1918 (also Corythoderini). Some character states shared with the distantly-related termitophilous scarab genus Termitotrox Reichensperger, 1915 (Termitotrogini) are noted, and proposed as convergent.

Abstract:
The consumption of insect including termites is gaining more interest nowadays even though many people still ignore the great benefit of enthomophagy. This study is a contribution to the valorization of Macrotermesalates in Lome (southern Togo). For this purpose, a survey was carried out in three municipalities of Golfe 3, Golfe 7 and Agoe-Nyive 1 (all located in the district of Lome) from June 14 to July 14, 2021. A total of 345 people were submitted to a set of questionary to assess the level of their knowledge and consequences related to the consumption of Macrotermes alates. The results revealed that more than 94% of the participants not only had a good knowledge of Macrotermes alates, but have also consumed them. Among the surveyed people, 48.67% consumed these alates for their taste while 28.67% consumed them for their nutritional value. Also, 43.70% of participants who had once consumed these alates, stated that they experienced gastrointestinal troubles following the consumption. Thus, although it is important to encourage the consumption of Macrotermes alates, hygienic precautions should be taken during the collection and processing of these alates in the interest of the health safety of consumers.

Abstract:
Le termite macrotermes bellicosus (isoptere) est present dans toute l'afrique subsahelienne jusqu'aux confins de l'afrique australe. Cette vaste repartition geographique peut entrainer chez les populations qui evoluent dans des habitats differents des divergences genetiques. Des echantillons sont preleves en cote d'ivoire et au tchad. Dans des conditions de restriction alimentaire les individus du tchad ont un taux de survie plus eleve que ceux de la cote d'ivoire. Des analyses morphometriques sur les soldats revelent une variation intra et inter-population. Cependant, l'etude de quelques enzymes digestives ne montre aucune difference qualitative particuliere entre les populations. Une etude electrophoretique de 22 loci montre que 19 sont monomorphes. Le pourcentage de loci polymorphes n'est que de 13%. Macrotermes bellicosus presente une variabilite electrophoretique moins elevee que beaucoup d'autres insectes. Cette faible diversite genetique chez macrotermes bellicosus, dont les individus sont tous diploides, est semblable a celle d'autres insectes sociaux comme les hymenopteres qui comptent des membres haploides dans leurs colonies. Les loci polymorphes, (l'esterase, l'amylase, la -glucosidase) permettent de constater des taux de polymorphisme differents, 14% et 4,5% respectivement en cote d'ivoire et au tchad. Cependant la distance genetique de 0,058 entre les deux populations est faible. Une derive genetique inherente aux insectes sociaux ou une pression de selection differente sur les deux populations peuvent expliquer ces observations. La -glucosidase dont le profil electrophoretique est specifique a chaque population a ete purifiee. La comparaison des proprietes des -glucosidases d'individus des deux pays revele des differences structurales et biochimiques. Ces differences sont en relation avec les contextes climatiques des pays ou les echantillons ont ete preleves traduisant ainsi une adaptation de chaque population a son environnement.

Abstract:
Macrotermitinae mounds could hold the key for designing a naturally ventilated human habitation using the sustainable Solar and Wind energies. Few attempts were made to mimic these structures into man build structures to achieve natural ventilation. Yet the limited understanding of the ventilation mechanisms applied in these mounds and the lack of fully developed building technologies capable of implementing such complex designs have prevented its further implementation in human habitation. A number of ventilation mechanisms were proposed, however, they are yet to be established. A prerequisite for a thorough understanding of the ventilation mechanism is the comprehension of the role of the mound skin in controlling of ventilation. This thesis focused on studying the flow through the porous mound skin into and out of the mound interior and the flow around the external skin surface. The Macrotermes michaelseni mound structure was visualised and studied in detail by means of field experiments to reveal its plaster-filled internal structure and digital scanning of a plaster-filled mound. The dimensions and interconnectivity of the internal conduits were examined to establish the source of maximum flow resistance. The mound skin and the built-in egress channels were found to be responsible for the bulk of the flow resistance. Computational Fluid dynamics CFD was used to predict the flow rates through the mound skin structure and the internal and external flow patterns. A series of Micro-CFD simulations were conducted to examine the effect of egress channel on the predicted flow rate through the porous mound skin. The effect of the mound conical shape on the external pressure distribution and flow patterns around and within the mound were predicted by Macro-CFD simulation. Wind tunnel experiments were conducted to validate the Macro-CFD analysis. Egress channels are present across the height of the mound stemming from a network of surface conduits that is directly below the mound skin. The surface conduits are highly connected to each other, to the mound central chimney and to the nest structure via peripheral subterranean conduits creating a highly connected network of air conduits. Egress channels keep the mound internal conduits separate from the ambient environment under normal conditions of dry weather. These channels are opened to the skin external surface under rainy conditions to compensate for mound skin diminished air permeability. The flow through the mound skin with closed egress channels is highly sensitive to changes in the egress channel depth from the external skin surface rather than changes in the skin thickness. Closed egress channels within the mound skin doubles the flow rate through the mound. This exceeds the amount necessary for the colony metabolism to allow for part of the inflow to circulate the mound conduits and leave without reaching the subterranean nest structure. Open egress channels increase the flow rate by 1.3 times that of closed egress channels which is necessary during rainy conditions where the mound skin is impermeable. The mound spire is the most efficient in capturing air flow into the mound allowing just under 70% of the total flow rate through the mound skin. Fresh air enters the mound from the upwind conduits with an internal flow velocity ranging from 3 - 12 mm/s. Spent air leaves the mound interior from the lateral and downwind sides. The mound conical shape results in directing the inflow downwards and the outflow upwards.

Abstract:
A comprehensive study of carbon metabolism has been carried out on representatives of two genera of higher termites, Nasutitermes walkeri and the fungus gardeners, Macrotermes spp. Substantial activity of cellulase and its components endo-B-l,4—glucanase and B—glucosidase, was found in workers of N. walkeri, Macrotermes michaelseni M. subhyalinus, M. bellicosus and M. mulleri. Less activity was found in the soldiers and none in the larvae of the Macrotermes spp. In fungal material associated with Macrotermes spp. only the fungal nodules had significant enzyme activity. In N. walkeri and M. michaelseni at least 90% of all enzyme activities was found in the midgut, with the exception of endo-B-l,4-xy1anase activity which was not measured in M. michaelseni. Low levels of endo-fi-l,4—xylanase activity were evenly distributed throughout the gut of N. walkeri. Midgut enzyme activity was restricted to the anterior region. The salivary glands contained variable amounts of enzyme activities. Less than 5% of the endo-B-l,4— glucanase activity was located in the hindgut. The endogenous cellulase from N. walkeri consisted of multiple B-glucosidase and endo-B-1,4- glucanase components. Elution profiles of fungal endo-B—l,4—glucanase activities on Bio-Gel® P-150 indicate that each Macrotermes spp. has a different Termitomyces sp. associated with it, consisting of one to three endo-B-l,4-glucanase activities. Endo-B-1,4-glucanase components from termite workers also consisted of one to three enzymes. A comparison of the elution profiles on Bio-Gel® P-60 of endo-B-lA—glucanase and Bglucosidase activities from fungal and termite material was used to show the absence of fungal enzymes in the termite gut. Similar results were found with fungal and termite material from M. bellicosus and M. mulleri using Bio-Gel® P—150 chromatography.

Abstract:
Approximately 30 million years ago, ancestors of fungus-growing termites started an obligate mutualistic relationship with a Basidiomycete fungus Termitomyces. The success of this obligate relation is the division of labour and reliance on termite caste gut microbial symbionts. Termites workers maintain Termitomyces fungal garden with their workforce and dual gut passage while the soldier caste protects the colony from predators. The fungal garden concurrently provides enough food for the colony members. Royal pair (a king and a queen) is the centralised caste in the colony, and they control the colony population by their massive reproduction, but their gut community composition remains unexplored. This project aimed to characterise the gut microbes associated with royal pairs of a fungus‐growing termite species Macrotermes natalensis. Four colonies were explored using high throughput sequencing of 16S rRNA gene amplicon dataset. The high-throughput sequence result showed that royal gut microbiotas were comprised of a lower number of bacterial taxa than sterile caste (workers and soldiers). This less number of bacterial taxa suggested that the royal pair gut was completely decoupled from the sterile castes gut, which indicates that the royal pair were possibly provided with a unique diet. The study also showed diversity in bacterial genus-level OTUs of royal pairs in all four colonies which indicated that there is a diet variation between the king and queen. The media predicting strategy could facilitate future cultivation efforts for targeted royal pair gut bacterial strains.

Abstract:
Nous avons essaye de preciser quelles etaient les relations symbiotiques qui existaient entre le termite macrotermes bellicosus et le champignon qu'il cultive dans son nid. Le role de la meule a d'abord ete etudie dans les constructions des ouvriers en elevage. Les cinetiques et les vitesses d'incorporation des sucres reducteurs et des proteines dans les constructions montrent l'importance de la meule dans l'activite constructive des ouvriers. Par ailleurs, l'etude du metabolisme digestif des ouvriers de macrotermes bellicosus et de leur champignon symbiotique a permis de mettre en evidence leur caractere fortement xylanolytique. L'activite cellulolytique a une composante mineure de leur metabolisme. Afin de preciser les modalites de la symbiose digestive chez macrotermes bellicosus, nous avons donc entrepris la purification des complexes xylanolytiques et d'une des composantes du complexe cellulolytique presents dans le tube digestif du termite et dans les mycotetes de son champignon symbiotique. Au total 7 enzymes ont ete purifiees. Chez le termite, le complexe xylanolytique est constitue d'une endoxylanase, d'une exoxylanase et d'une beta-xylosidase. Chez le champignon symbiotique, il est constitue d'une endoxylanase et d'une exoxylanase. Deux endocellulases ont ete egalement purifiees, l'une a partir du tube digestif du termite, l'autre a partir des mycotetes du champignon symbiotique. La comparaison des proprietes biochimiques et structurales de ces enzymes nous permet d'affirmer que l'endoxylanase et l'endocellulase du termite sont d'origine fongique. Sur les trois enzymes purifiees a partir des mycotetes seules deux sont presentes dans le tube digestif des ouvriers. Le role de l'endoxylanase dans la physiologie digestive du termite a ete precise par des experiences de survie d'ouvriers places dans differentes conditions alimentaires completees par des dosages de leur activite xylanasique. Des mycotetes comme seule source d'alimentation n'augmentent pas la duree de survie des ouvriers mais permettent une forte augmentation de l'activite xylanasique. L'endoxylanase est donc capable de s'accumuler dans le tube digestif des ouvriers. Par ailleurs, une etude de l'action en synergie, entre l'endoxylanase et l'exoxylanase du termite, a ete effectuee. Un melange constitue par 20 pour cent d'endoxylanase et 80 pour cent d'exoxylanase conduit a une augmentation de 90 pour cent de l'activite specifique. Ces deux enzymes issues d'organismes differents degradent donc en synergie le xylane. L'endoxylanase, acquise par le termite en consommant des mycotetes, complete son equipement enzymatique et lui permet de degrader avec plus d'efficacite le xylane

Abstract:
Cette étude vise à décrire les caractéristiques agropédologiques des nids de M. Subhyalinus et d'O. Magdalenae et à déterminer leur importance dans deux agrosystèmes du nord du Cameroun. Elle montre que les propriétés pédologiques des nids font de ces stations un élément indépendant du découpage du parcellaire et de la conduite des itinéraires techniques. Dans les sols ferrugineux de piémont, les nids de Macrotermes génèrent de véritables îlots de fertilité desquels sont dégagées des productions substantielles en céréale. En redistribuant des argiles 2/1 en surface du sol, ils augmentent la CEC et les teneurs en cations échangeables, tout en favorisant la structuration des horizons superficiels. Dans les vertisols, les nids d'Odontotermes détruits se singularisent par une forte macroporosité qui leurs confère un comportement hydrique et mécanique spécifique. L'hétérogénéité ainsi créée est valorisée pour réduire la durée des pépinières de muskuwaari et étaler les chantiers de repiquage
This work aims to describe the agropedologic characteristics of the mounds built by M. Subhyalinus and O. Magdalenae and to specify their role in two farming systems of the north of Cameroon. It shows that the singular pedological properties of the nests put these stations as an area independent of the field pattern and the crop managment. On an arenitic alfisol, the mounds of Macrotermes create true islands of fertility from which substantial productions of cereals are obtained. By redistribuiting 2/1 clays on the soil surface, they increase the CEC and the contents of exchangeable cations, while promoting structuring processes. On a vertisol, the mounds of Odontotermes, after their pulling-down, are made conspicuous by a strong macroporosity which confer theni specific water retention and particular mechanical behavior. Heterogeneity thus created s used to reduce the time required for seedbeds of muskuwaari and to lengthen the operations of the transplanting of sorghum

Abstract:
Termites are important soil engineers, responsible for decomposing organic matter, recycling nutrients, and creating habitats for other organisms. But some species cause damage, including several genera that attack cacao trees. These include termites belonging to the genera Macrotermes, Nasutitermes, Microcerotermes, Ancistrotermes, and Coptotermes. Some are mound-builders, while others construct carton nests of faeces and wood on tree trunks, or small dome-shaped mounds on trees. Twenty years ago, the termite Macrotermes bellicosus was not thought to damage cacao, but today, it is considered a major pest of the crop, responsible for significant damage to seedlings and even mature trees. This chapter examines termite biology and looks at how they damage cacao trees and what can be done to manage the problem.
