Mosquitoes are vectors for arboviruses such as dengue, Zika, and Chikungunya. Symbiotic interactions can affect the intrinsic ability of mosquitoes to acquire and transmit arboviruses, e.g., vector competence. Insect specific viruses (ISVs) are commonly found in symbiotic associations with mosquitoes in the wild and can affect many aspects of mosquito biology. Here, we review current knowledge on the effects of symbiotic ISV-mosquito interactions on vector competence. We discuss potential mechanisms underlying these interactions and their implications for shaping new biological control strategies...

Leigh Boardman
Low temperatures are rarely experienced in isolation. The impacts of low temperatures on insects can be exacerbated or alleviated by the addition of other environmental factors, including, for example, desiccation, hypoxia, or infection. One way in which environmental factors can interact is through cross-talk where different factors enact common signaling pathways. In this review, I highlight the breadth of abiotic and biotic factors that can interact with low temperature tolerance in both natural and artificial environments; and discuss some of the candidate pathways that are possibly responsible for cross-talk between several factors...

Brittany Faye Peterson
Insect gut bacteria have been implicated in a myriad of physiological processes from nutrient supplementation to pathogen protection. In fact, symbiont-mediated insecticide degradation has helped explain sudden control failure in the field to a range of active ingredients. The mechanisms behind the loss of susceptibility are varied based on host, symbiont, and insecticide identity. However, while some symbionts directly breakdown pesticides, others modulate endogenous host detoxification pathways or involve reciprocal degradation of insecticidal and bactericidal compounds both inspiring new questions and requiring the reexamination of past conclusions...

Jian Pu, Henry Chung
The continuous use of insecticides over the last eight decades has led to the development of resistance to these insecticides. Research in the last few decades showed that the mechanisms underlying resistance are diverse but can generally be classified under several modes of resistance such as target-site resistance, metabolic resistance, and penetration resistance. In this review, we highlight new discoveries in insecticide resistance research made over the past few years, including an emerging new mode of resistance, sequestration resistance, where the overexpression of olfactory proteins bind and sequester insecticides in resistant strains, as well as recent research on how post-transcriptional regulation can impact resistance...

Detecting looming motion directly towards the insect is vital to its survival. Looming detection in two insects, flies and locusts is described and contrasted. Pathways using looming detectors to trigger action and their topographical layout in the brain is explored, in relation to facilitating behavioural selection. Similar visual stimuli, such as looming motion are processed by nearby glomeruli in the brain. Insect inspired looming-motion detectors are combined to detect and avoid collision in different scenarios by robots, vehicles and UAVs...

REVIEW
Kohei Oguchi, Toru Miura
In social insects, interactions among colony members trigger caste differentiation with morphological modifications. During caste differentiation in termites, body parts and caste-specific morphologies are modified during postembryonic development under endocrine controls such as juvenile hormone and ecdysone. In addition to endocrine factors, developmental toolkit genes like Hox genes and appendage-patterning genes also contribute to the caste-specific body part modifications. These toolkits are thought to provide spatial information for specific morphogenesis...

REVIEW
Ayako Wada-Katsumata, Coby Schal
The German cockroach is a valuable model for research on indoor pest management strategies and for understanding mechanisms of adaptive evolution under intense anthropogenic selection. Under the selection pressure of toxic baits, populations of the German cockroach have evolved a variety of physiological and behavioral resistance mechanisms. In this review, we focus on glucose aversion, an adaptive trait that underlies a behavioral resistance to baits. Taste polymorphism, a change in taste quality of glucose from sweet to bitter causes cockroaches to avoid glucose-containing baits...

Historically some of the most effective tools to counter vector-borne diseases have been those directed against the vectors. Ticks are undergoing a population explosion as evidenced by the recent expansion of their distribution range. Tick control has traditionally relied heavily on pesticides. However, sustained use of acaricides is resulting in resistant tick populations. Multi-pronged management strategies that build and expand upon innovative control methods are sorely needed. Behavior modifying chemicals, referred to as semiochemicals, such as pheromones and repellents offer a first line of personal protection against ticks...

Mosquitoes express a rich repertoire of daily 24-hour rhythms in biochemistry, physiology and behavior. The nocturnal Anopheles and Culex, and diurnal Aedes mosquitoes are major vectors of human disease, transmitting parasites and arboviruses such as malaria and dengue. In this review we explore the role that 24-hour diel and circadian rhythms play in shaping the temporal life of the mosquito. We focus on recent advances in our understanding of behavioral rhythms, focusing on locomotor/flight activity, host-seeking, biting/blood feeding and mating...

Identifying and understanding behavioral resistance to insecticides is vital for maintaining global food security, public health, and ecological balance. Behavioral resistance has been documented to occur in a multitude of insect taxa dating back to the 1940s but has not received significant research attention due primarily to the complexities of studying insect behavior and a lack of any clear definition of behavioral resistance. In recent years, a systematic effort to investigate the mechanism(s) of behavioral resistance in pest taxa (e...

The Aedes mosquito, which transmits the dengue fever virus and other viruses, has acquired resistance to pyrethroid insecticides in a naturally selective manner. Massive use of insecticides has led to the worldwide expansion of resistant populations. The major factor in pyrethroid resistance is knockdown resistance (kdr) caused by amino acid mutation(s) in the voltage-gated sodium channel, which is the target site of this insecticide group. Some kdr mutations can lead to a dramatic increase in resistance, and multiple mutations can increase the level of pyrethroid resistance by 10 to several-hundred...

Cameron R Fay, Amy L Toth
Are traits with high levels of plasticity more complex in their genetic architecture, as they can be modulated by numerous different environmental inputs? Many authors have assumed that behavioral traits, in part because they are highly plastic, have an exceptionally complex genetic basis. We quantitatively summarized data from 31 genome wide association studies and 87 traits in Drosophila melanogaster and found no evidence that behavioral traits have fundamental differences in number of single nucleotide polymorphisms or the significance or effect size of those associations, compared to non-behavioral (morphological or physiological) traits...

Many indoor urban pest insects now show a near-global distribution. The reasons for this may be linked to their cryptic behaviors which makes unintentional transport likely, tied to their reliance on human-mediated dispersal which can result in spread over potentially long-distances. Additionally, numerous species exhibit an array of mechanisms that confer insecticide resistance. Using population genetics, it is possible to elucidate the genetic characteristics that define globally successful indoor urban pest insect species...

Global climate changes undermine the effectiveness of "set and forget" phytosanitary regulations. Uncertainties in future greenhouse gas emission profiles render it impossible to accurately forecast future climates, thus limiting the ability to make long-term biosecurity policy decisions. Agile adaptive biosecurity frameworks are necessary to address these climatic uncertainties and to effectively manage current and emerging threats. This paper provides opinions on these issues and presents a case study focusing on the threats posed by Aleurocanthus woglumi (citrus blackfly) to Europe...

As obligate blood-feeders, ticks serve as vectors for a variety of pathogens that pose threats on both human and livestock health. The microbiota that ticks harbor play important roles in influencing tick nutrition, development, reproduction, and vector. These microbes also affect the capacity of ticks to transmit pathogens (vector competence). Therefore, comprehending the functions of tick microbiota will help in developing novel and effective tick control strategies. Here, we summarize the effects of main tick symbiotic bacteria on tick physiology and vector competency...

Ticks are obligatory hematophagous arachnids, serving as vectors for a wide array of pathogens that can be transmitted to humans or animals. The ability of tick-borne pathogens to maintain within natural reservoirs is intricately influenced by the attractiveness of ticks to their animal hosts, including humans. However, the complex dynamics of tick behavior and host-seeking strategies remain understudied. This review aims to summarize the impact of volatiles or odors on tick behavior and vector competence. Our literature review has identified a selection of compounds, such as 1-octen-3-ol, hexanal, heptanal, nonanal, 6-methyl-5-hepten-2-one, acetone, and octanal, as having the potential to impact both ticks and mosquitos' behaviors...

Insecticide resistance is an evolved ability to survive insecticide exposure. Compared to nonsocial insects, eusocial insects have lower numbers of documented cases of resistance. Eusocial insects include beneficial and pest species that can be incidentally or purposely targeted with insecticides. The goal of this review is to explore factors that either limit resistance or the ability to detect it in eusocial insects. We surveyed the literature and found that resistance has been documented in bees, but in other pest groups like ants and termites, the evidence is more sparse...
