Summary: The development of baits for subterranean termite control in the past 25 years has provided cost-effective alternatives to liquid termiticides, with benzoylurea chitin synthesis inhibitors (CSIs) being the main focus. Despite ample evidence of the efficacy of CSI baits, most studies have focused on hexaflumuron and noviflumuron, while the efficacy of alternative CSIs like novaluron remains under scrutiny. Independent testing of novaluron bait against Coptotermes gestroi in the laboratory confirmed its effectiveness in colony elimination.

Summary: Nitrogen is suggested to play a role in the behavior of subterranean termites returning to the nest to molt. Marked exuviae of Coptotermes gestroi were fed to colonies, and the marker was detected in every caste and life stage except first-instar larvae. The trophic path of consumed exuviae includes direct feeding and secondary trophallaxis.

Summary: The morphological characteristics of soldier caste in termites provide taxonomic information at the species level. The study conducted linear and geometric morphometrics analyses to analyze head capsule shape of soldier caste specimens of Coptotermes from Indonesia. Different head-shape variations were observed, with three extreme shapes found in C. gestroi. The lateral expansion of the posterior part of the head capsule across species was correlated with the number of hairlike setae on the pronotum and head.

Summary: The traditional stake survey and in-ground (IG) monitoring stations are ineffective in aggregating the Asian subterranean termite, Coptotermes gestroi (Wasmann) in southeastern Florida. However, above-ground (AG) Sentricon stations with 0.5% noviflumuron were successfully used to eliminate C. gestroi colonies with an average elimination time of 6.4 - 8.0 weeks.

Summary: This study investigated ovarian development and oogenesis in the Asian subterranean termite Coptotermes gestroi, and found that ovarian development and functionality are age-dependent, with younger individuals possessing immature oocytes and functional queens always having mature terminal oocytes. Oogenesis in alate females was not uniform, and non-functional neotenics displayed variation in ovarian development. These reproductive features should be considered in evaluating their impact on colony development.

Summary: This study investigated the efficacy of chitinase and protease produced by Bacillus licheniformis PR2 as cuticle-degrading enzymes for the biocontrol of worker termites. Treatment with the bacterial broth culture and the crude enzyme fraction of B. licheniformis PR2 resulted in high mortality rates and visible damage to the termites' cuticles. These results suggest that the enzymes produced by B. licheniformis PR2 represent an effective eco-friendly strategy for controlling termite damage.

Summary: In this study, the phenotypic traits of F1 hybrid colonies of two destructive subterranean termite species were investigated. The nest architecture and soldier morphological traits of the hybrid colonies were compared to those of the parental species. It was found that the carton materials in the hybrid colonies were disorganized and the soldier morphometric traits varied across different mating combinations. However, four qualitative morphological differences were identified for soldier identification of hybrid Coptotermes.

Summary: This study investigated the factors involved in the development of polygamous colonies of C. cumulans and found that polygynous colonies lay more eggs but not twice as many as monogamous colonies. Monogamous colonies produced more larvae until the appearance of workers. Larvae were rarely observed in polygynous colonies, possibly due to cannibalism by one of the queens.

Summary: This study provides a morphological approach to the gut regions in pseudergates and soldiers of S. serrifer, focusing on the ultrastructure features of the paunch and its association with microbial communities. The findings suggest that content uptake and bacterial attachment occur along the epithelium in the paunch rather than in specific sites. The morphology of S. serrifer's gut resembles that of other lower termites, but lacks cup-like depressions found in Rhinotermitidae species.

Summary: The spermathecae of Coptotermes gestroi undergo morphometric and physiological changes after mating, suggesting that sperm storage continues and secretory activity intensifies after pairing. The ultrastructure of the spermathecal epithelium shows the presence of secretory cells and associated canal cells, with an increasing synthesis of proteins in mated queens. Further analysis may provide insights into the chemical nature of the spermathecal secretion before and after mating.

Summary: In this review, the authors summarize the distribution, morphological features, and likely function of the 22 exocrine glands described for termites. These glands play a crucial role in termite communication and are also involved in defense, building, foraging, and physiological processes such as enzyme synthesis and the production of antiseptic and lubricant compounds. The exocrine systems in termites comprise different types of secretory cells and the composition of these cells varies among glands. Some glands have well-known chemical compositions and functions, while others remain speculative or unknown. The number of termite exocrine glands is relatively low compared to eusocial Hymenoptera species, possibly due to the higher species diversity and chemical communication in the latter. Further research is needed to understand the occurrence, function, and modulation of termite exocrine systems in different activities.

Summary: Little is known about how animals overcome temporal constraints on movement during dispersal. This study used GPS tracking of vulturine guineafowl and found that dispersers showed the greatest increase in movement at the same times of day when they moved the most prior to dispersal. These findings suggest that individuals face the same ecological constraints during dispersal as they do in daily life and achieve large displacements by maximizing movement when conditions are most favorable.

Summary: Environmental conditions, particularly temperature, have a significant impact on animal behavior. This study focused on aggression in Neolamprologus pulcher fish and found that aggression rates increased with temperature at lower levels, but decreased after reaching a peak. Additionally, the influence of high temperatures on aggression changed over time during the trials. These findings provide a more comprehensive understanding of the short-term effects of temperature on aggression and highlight the importance of considering non-linear changes in thermal performance.

Summary: Human activities have affected the availability of resources for wildlife, particularly through the provision of anthropogenic food subsidies at landfill sites. This study explores the influence of age on landfill attendance and foraging behavior in white storks. Adult storks visit landfills more frequently and show dominance over juveniles in food acquisition. Juveniles have limited access to landfill resources and are forced to use lower quality areas.
