Factors influencing pyrethroid barrier spray effectiveness against Aedes mosquitoes
… were examined in these studies: Demand® CS (lambda-cyhalothrin), Talstar® Professional (bifenthrin), and Suspend® Polyzone® (deltamethrin). The following factors affecting pyrethroid barrier treatments showed significant impacts on the knockdown and mortality rates of Ae. albopictus …

Optimizing Trichogramma ostriniae (Hymenoptera: Trichogrammatidae) releases to control European corn borer, Ostrinia nubilalis (Lepidoptera: Crambidae) in bell pepper
… conventional insecticides, acephate, and lambda-cyhalothrin. At most locations, multiple sprays of lambda-cyhalothrin resulted in flares (outbreaks) of green peach aphids most likely from destruction of arthropod natural enemies. Indoxacarb also caused a similar aphid flare at one of the …

Ecotoxicology of Natural and Anthropogenic Extreme Environments
… were acutely toxic to blue crabs in the order of Lambda-cyhalothrin > imidacloprid ≈ aldicarb > acephate ≈ Roundup® (glyphosate). Megalopae were almost always more sensitive to pesticides than early stage juveniles. Commercial formations of pesticides generally showed similar toxicity to active …

Biology and Management of Brown marmorated Stink Bug, Halyomorpha halys (Stål), in Agricultural and Urban Environments
… lost efficacy after 29 DAT except for lambda-cyhalothrin, beta-cyfluthrin, beta-cyfluthrin + imidacloprid, lambda-cyhalothrin + thiamethoxam, and dinotefuran, which had some measureable activity even after 40 DAT. Each of these insecticides contained a pyrethroid alone or in combination …

Quantification of insecticide resistance in the tobacco-adapted form of the green peach aphid, Myzus persicae (Sulzer)(Hemiptera: Aphididae)
… classes of insecticides, acephate, imidacloprid, lambda-cyhalothrin, and methomyl. The temperature change from 15 to 20°C caused almost a 3-fold increase in toxicity to the red and green color morphs for methomyl, acephate, and imidacloprid. In contrast, the toxicity of lambda-cyhalothrin …

The cabbage whitefly, aleyrodes Proletella: causes of outbreaks and potential solutions
… factors. A diagnostic concentration of lambda-cyhalothrin was identified and used to screen further populations over successive years. No cross-resistance to neonicotinoid insecticides was evident in highly pyrethroid-resistant populations. Bioassays with the synergist piperonyl butoxide …

Management of the soybean aphid, Aphis glycines Matsumura (Hemiptera: Aphididae), in Iowa
… effect on soybean yield from an insecticide (lambda-cyhalothrin) application made below the current 250 A. glycines per plant economic threshold. Insecticide applications made at 250 A. glycines per plant protected yields when A. glycines populations continued to increase in the control …

Evaluating the effect of foliar insecticides on suspected Bt-resistant western corn rootworms in rotated soybean
… (1) an early application of Warrior II (lambda-cyhalothrin) applied during the tasseling stage of nearby corn, (2) a late application of Warrior II applied when nearby corn silks were brown, and (3) an untreated check. Adult western corn rootworm abundance in soybean was evaluated using …

Characterising the role of climate change in perpetuating Zimbabwean farmers' health risks from exposure to endocrine disrupting pesticides
… of concern. Amitraz, endosulfan, fenvalerate and lambda-cyhalothrin were determined as having a high likelihood of acting as endocrine disruptors, as validated by literature highlighting the four pesticides' hormone-related cognitive, physiological and reproductive adverse health effects. Findings …

Stink bug egg studies in southeastern Virginia: parasitoid survey, and susceptibility and chorion permeability to insecticides
… bioassays and field applications of acephate, lambda-cyhalothrin, spinosad, and thiamethoxam, were carried out to determine efficacy against nonparasitized E. servus and A. hilare eggs, and T. podisi embryos developing in E. servus eggs. Results showed that eggs of both species were susceptible …

Susceptibility of Oriental fruit moth, (Grapholita molesta (Busck)) to selected insecticides and mixtures
… acetamiprid, thiamethoxam, esfenvalerate, and lambda-cyhalothrin, neonates were placed on wheat germ diet containing a range of concentrations of each insecticide. Overall, the two colonies responded similarly to these insecticides, regardless of parental food source. Results of these bioassays …
