The South American tomato pinworm, Tuta absoluta (Meyrick) (Lepidoptera: Gelechiidae), is a devastating invasive pest of crops in several areas around the world including Africa. Here, we comprehensively review and discuss relevant scientific knowledge on its occurrence, biological ecological aspects, fortuitous insect natural enemies, potential advantages constraints management scenarios adopted against this both Northern Sub-Saharan We conclude manuscript with comprehensive research agenda...
Abstract The yellow fever mosquito, Aedes aegypti , particularly in Neotropical regions, is the principal vector of dengue, fever, Zika and Chikungunya viruses. Pyrethroids remain one most used insecticides to control mosquitoes, despite development pyrethroid resistance many mosquito populations worldwide. Here, we report a Brazilian strain A. with high levels (approximately 100–60,000 fold) both type I II pyrethroids. We detected two mutations (V410L F1534C) sodium channel from this...
Since 2016, the fall armyworm (FAW) Spodoptera frugiperda has spread over extensive areas of tropics and subtropics, imperiling food security, economic progress livelihoods millions cereal farmers. Although FAW received long-standing scientific attention in its home range Americas, chemical inputs feature prominently mitigation biological control uptake is globally lagging. Here, building upon a quantitative review global literature, we methodically dissect science. Of known entomopathogens...
The tomato leaf miner, Tuta absoluta (Lepidoptera) is a significant pest of tomatoes that has undergone rapid expansion in its range during the past six years and now present across Europe, North Africa parts Asia. One main means controlling this through use chemical insecticides. In current study insecticide bioassays were used to determine susceptibility five T. strains established from field collections Europe Brazil pyrethroids. High levels resistance λ cyhalothrin tau fluvalinate...
Abstract We provide an overview of both traditional and innovative control tools for management three Xylosandrus ambrosia beetles (Coleoptera: Curculionidae: Scolytinae), invasive species with a history damage in forests, nurseries, orchards urban areas. compactus , X. crassiusculus germanus are native to Asia, currently established several countries around the globe. Adult females bore galleries into plant xylem inoculating mutualistic fungi that serve as food source developing progeny....
Essential oils have been suggested as suitable alternatives for controlling insect pests. However, the potential adaptive responses elicited in insects mitigating actions of these compounds not received adequate attention. Furthermore, is widely reported with traditional insecticides, sublethal exposure to essential might induce stimulatory or contribute development resistance strategies that can compromise management The current study evaluated locomotory and respiratory well number larvae...
Background The use of synthetic insecticides is one the most common strategies for controlling disease vectors such as mosquitos. However, their overuse can result in serious risks to human health, environment, well selection insecticidal resistant insect strains. development efficient and eco-friendly control urgent, essential oils have been presented potential alternatives insecticides. Moreover, nanoencapsulation techniques enhance efficiency by protecting from degradation providing a...
The control of the most important pest stored maize, weevil Sitophilus zeamais Motschulsky (Coleoptera: Curculionidae), is mainly achieved with use pyrethroid insecticides. However, intensive these compounds has led to selection resistant populations and compromised efficacy this insect pest. Here, toxicity indoxacarb for a potential in S. was assessed on 13 Brazilian populations. Concentration–mortality bioassays, presence synergists (piperonyl butoxide, triphenyl phosphate, diethyl...
Environmental stress in newly-emerged adult insects can have dramatic consequences on their life traits (e.g., dispersion, survival and reproduction) as adults. For instance, sublethally exposed to environmental stressors insecticides) gain fitness benefits a result of hormesis (i.e., low doses compounds that would be toxic at higher doses). Here, we experimentally tested whether sublethal exposure the insecticide imidacloprid hormetically affect sexual adults Neotropical brown stink bug...
Abstract BACKGROUND: Tuta absoluta (Meyrick) is one of the most serious pests tomato recently introduced in Mediterranean region. A novel bioassay method designed for accurate determination insecticide toxicity on T. ( IRAC No. 022) was validated by three different laboratories [Greece NAGREF ), Italy UC ) and Spain UPCT )] European populations. RESULTS: The insecticides indoxacarb chlorantraniliprole were used as reference products. leaf dip easy to perform, producing repeatable,...
The use of plant essential oils has been shown to efficiently control insect pests stored beans, significantly reducing the threats associated with synthetic insecticides. Here, we evaluated potential applications clove, Syzygium aromaticum L., and cinnamon, Cinnamomum zeylanicum Callosobruchus maculatus, considered as one most cosmopolitan beans. Using four combinations couples (i.e., unexposed couples, exposed females, males, couples), also how sublethal exposure these impacted C....
Abstract Studies on insecticide-induced stimulatory effects in pest insects have become of utmost importance due to their potential implications management. Temperature influences the physiology and biology ectothermic organisms like insects. It can also affect toxicity relative efficacy insecticides that are used agricultural fields. However, impact temperature insect responses after exposure mild stresses has frequently been overlooked. Here, we investigated how different levels (15; 20;...
Leaf-cutting ants are the most important pests in several cropping systems Neotropics. Granulated baits containing active ingredients, considered hazardous by Stockholm Convention, usual method to control these ants. Isocycloseram is a new insecticide molecule with high safety margin for mammals, but without registration general. Thus, this study investigated effectiveness of granulated isocycloseram leaf-cutting under laboratory and field conditions. Initially, mortality Atta sexdens...
Abstract The tomato leaf miner, Tuta absoluta (Lepidoptera: Gelechiidae), is a major invasive pest that has spread throughout many countries in the Mediterranean basin and parts of Asia over last decade. control T. relied heavily on use chemical insecticides, strategy led to evolution resistance. In this study, biological molecular methods were used determine susceptibility five strains organophosphate chlorpyrifos investigate mechanisms underlying resistance class insecticides. High levels...
Abstract Although the cultivation of transgenic plants expressing toxins Bacillus thuringiensis ( Bt ) represents a successful pest management strategy, rapid evolution resistance to in several lepidopteran pests has threatened sustainability this practice. By exhibiting favorable safety profile and allowing integration with initiatives, plant essential oils have become relevant control alternatives. Here, we assessed potential extracted from Neotropical plant, Siparuna guianensis Aublet,...
Abstract Target-site mutations and changes in insect metabolism or behavior are common mechanisms insecticide-resistant insects. The co-occurrence of such a pest strain is prominent threat to their management, particularly when alternative compounds scarce. Pyrethroid resistance among stored grain weevils (i.e., Sitophilus spp.) an example long-standing concern, for which reports generally focus on single mechanism species. Here, we investigated pyrethroid maize rice zeamais S . oryzae ),...
