Bee Innate Immunity
As important pollinators, bees play a critical role in maintaining the balance of the ecosystem and improving the yield and quality of crops. However, in recent years, the bee population has significantly declined due to various pathogens and environmental stressors including viruses, bacteria, parasites, and increased pesticide application. The above threats trigger or suppress the innate immunity of bees, their only immune defense system, which is essential to maintaining individual health and that of the colony. In addition, bees can be divided into solitary and eusocial bees based on their life traits, and eusocial bees possess special social immunities, such as grooming behavior, which cooperate with innate immunity to maintain the health of the colony.

Deforestation, Urbanization, and Mosquito and Tick-Borne Diseases
Central America is a unique geographical region that connects North and South America, enclosed by the Caribbean Sea to the East, and the Pacific Ocean to the West. This region, encompassing Belize, Costa Rica, Guatemala, El Salvador, Honduras, Panama, and Nicaragua, is highly vulnerable to the emergence or resurgence of mosquito-borne and tick-borne diseases due to a combination of key ecological and socioeconomic determinants acting together, often in a synergistic fashion. Of particular interest are the effects of land use changes, such as deforestation-driven urbanization and forest degradation, on the incidence and prevalence of these diseases, which are not well understood. In recent years, parts of Central America have experienced social and economic improvements; however, the region still faces major challenges in developing effective strategies and significant investments in public health infrastructure to prevent and control these diseases.

Avian Malaria Vectors in Host-Seeking Behaviour
Vector-borne infectious diseases (e.g., malaria, dengue fever, and yellow fever) result from a parasite transmitted to humans and other animals by blood-feeding arthropods. They are major contributors to the global disease burden, as they account for nearly a fifth of all infectious diseases worldwide. The interaction between vectors and their hosts plays a key role driving vector-borne disease transmission.

Hyalomma Ticks and Human and Animal Health
Ticks are obligatory hematophagous ectoparasites that act as vectors for many important human and livestock pathogens worldwide. Like spiders and scorpions, they belong to the class Arachnida. Within the order Ixodida, most species of ticks belong to one of the two main large families, Argasidae or Ixodidae. The latter are known as “hard” ticks since they have a sclerotized dorsal plaque or scutum. In contrast, those belonging to the family Argasidae lack this physical feature and are therefore known as “soft ticks”. Tick-borne infectious diseases spread following the bite of infected ticks, which can carry and be infected by bacteria, viruses, or parasites. Some of the most important bacteria-infecting ticks include species of the genera Rickettsia, Borrelia, Francisella, Anaplasma, and Ehrlichia, as well as viruses such as the Crimea–Congo hemorrhagic fever (CCHF) virus, the West Nile virus, and the tick-borne encephalitis virus, among others.

Benefits of Insect Pollination in Brassicaceae
Cultivated Brassicaceae attract a wide variety of pollinators. In both self-compatible and self-incompatible crop species, meta-analysis indicates that seed yield (Y), silique set (SQS), number of siliquae/plant (NSQ), and the number of seeds/silique (NSSQ) increase when plants are insect-pollinated compared to when there is no insect pollination. The weight of seeds (WS), however, increased in self-incompatible species but not in self-compatible ones as a result of insect pollination. Overall, the percentage of studies showing a positive effect of insect pollination on yield parameters was higher in self-incompatible than in self-compatible species. It was shown that the ability of self-compatible species to reproduce does not fully compensate for the loss of yield benefits in the absence of insect pollination.

Cell Line Support Arthropod Immunity
Many insect and tick species are serious pests, because insects damage crop plants and, along with ticks, transmit a wide range of human and animal diseases. One way of controlling these pests is by impairing their immune system, which protects them from bacterial, fungal, and viral infections. An important tool for studying immunity is using long-lasting cell cultures, known as cell lines. Cell line research is a powerful method for understanding how invertebrates mount defenses against pathogenic organisms and testing hypotheses on how these responses occur. In particular, immortal arthropod cell lines are valuable tools, providing a tractable, high-throughput, cost-effective, and consistent platform to investigate the mechanisms underpinning insect and tick immune responses. Here we review how cell line research results inform the controls of medically and agriculturally important insects and ticks.

Human Consumption of Insects in Sub-Saharan Africa
There are 472 edible insect species in sub-Saharan Africa, of which 31% are Lepidoptera. Wild harvesting is still the main source of supply for these prized species to this day, with some harvesting techniques negatively impacting the environment. The successful production of edible caterpillars requires the appropriate and efficient implementation of husbandry techniques and practices.

Organic Insect Pest Management
The Federal National Organic Program (NOP) guidelines for insect pest management can be viewed as constraining to certified organic growers due to the disallowance of certain tactics such as synthetic insecticides and transgenically derived pest resistant crops. The types of insect pest management tactics that are promoted by the NOP require in-depth entomological knowledge for successful management such as pheromone disruption, augmentation and conservation biological control. There are significant gaps in the Federal NOP guideline recommendations, such as insect identification and population monitoring, that if included could aid in grower adoption of practices that inform better decision making and efficacy. This review promotes the idea that these issues can be overcome by utilizing experiential learning programs to educate growers and paid professionals like those who are a part of the California system of state licensed Pest Control Advisors (PCA) and having those paid advisors provide much needed individualized, hands-on grower guidance. If the PCA or paid professional is regarded as a valued partner in the educational and extension process of addressing pest management issues, they can be an effective advocate, educator, mentor and assessor for the growers; ultimately reaching more growers to ensure effective adoption and use of a variety of management tactics. This model has the capacity to achieve the NOP's philosophical goal of a production system managed to respond to site-specific conditions by integrating cultural, biological and mechanical practices for effective pest management.

Phenological Mapping of Invasive Insects
Phenological maps can depict the development and seasonal activities (phenology) of invasive insects at area-wide scales, such as counties, states, or entire nations. When regularly updated using real-time and forecast climate data, these maps may improve the timeliness of early detection and control tactics that target specific life stages. Rapid responses to invasive insects may increase the likelihood that populations are eradicated or controlled before they can spread or increase in size. Phenological maps may also be used to assess pest establishment risk, investigate pest–host interactions, and measure climate-driven changes in pest phenology.

Fire Ant Venom Alkaloids
Venoms produced by arthropods act as chemical weapons to paralyze prey or deter competitors. The utilization of venom is an essential feature in the biology and ecology of venomous arthropods. Solenopsis fire ants (Hymenoptera: Formicidae) are medically important venomous ants. They have acquired different patterns of venom use to maximize their competitive advantages rendered by the venom when facing different challenges. The major components of fire ant venom are piperidine alkaloids, which have strong insecticidal and antibiotic activities. The alkaloids protect fire ants from pathogens over the course of their lives and can be used to defend them from predators and competitors.

Applications of BNF and NWR Strategies in Insects
Nitrogen is usually a restrictive nutrient that affects the growth and development of insects, especially of those living in low nitrogen nutrient niches. In response to the low nitrogen stress, insects have gradually developed symbiont-based stress response strategies—biological nitrogen fixation and nitrogenous waste recycling—to optimize dietary nitrogen intake. Based on the above two patterns, atmospheric nitrogen or nitrogenous waste (e.g., uric acid, urea) is converted into ammonia, which in turn is incorporated into the organism via the glutamine synthetase and glutamate synthase pathways.

Management of Spodoptera frugiperda
The fall armyworm of maize, Spodoptera frugiperda (J. E. Smith) (Lepidoptera; Noctuidae) is capable of causing a 100% yield loss due to its unforeseen occurrence from the seedling to the cob formation stage. To manage this serious pest, maize growers are tending to apply a high dosage of pesticides. This indiscriminate usage of pesticides has resulted in an unacceptable amount of insect resurgence in maize, harming maize production and consumption.

RNAi for Western Corn Rootworm Management
The western corn rootworm (WCR), Diabrotica virgifera virgifera LeConte, is an annual pest of maize in the United States Corn Belt. Larval feeding on the root system can promote significant yield loss through reduced water and nutrient uptake and decreased plant stability. Various management tactics, including crop rotation, insecticides, and transgenic crops expressing Bacillus thuringiensis Berliner proteins, have been used to manage WCR densities. However, resistance has evolved to each of these tactics in local areas, highlighting the need for new management strategies. The use of RNA interference (RNAi) technology for WCR management represents the next phase of species-specific pest management.

Phylosymbiotic Relationship between Insects and Symbionts
Insects harbor diverse assemblages of bacterial and fungal symbionts, which play crucial roles in host life history. Insects and their various symbionts represent a good model for studying host–microbe interactions. Phylosymbiosis is used to describe an eco-evolutionary pattern, providing a new cross-system trend in the research of host-associated microbiota. The phylosymbiosis pattern is characterized by a significant positive correlation between the host phylogeny and microbial community dissimilarities.
