Pyrethroid Insecticide Resistance of Aedes albopictus and Aedes aegypti (Diptera: Culicidae) across the Hawaiian Islands.

Background (Skuse, 1894) and (Linnaeus, 1762) (Diptera: Culicidae) are invasive species in the Hawaiian Islands as well as other islands of the Pacific and serve as the primary vectors of arboviruses like dengue virus. Despite its significance to public health, data on their insecticide resistance remains limited. Knowledge of the level of insecticide resistance is critical in developing effective mosquito control strategies, especially when an arboviral disease outbreak occurs.

Population genomics of Aedes albopictus across remote Pacific islands for genetic biocontrol considerations.

Remote Pacific islands (RPI) are characterized by ecological isolation, diverse endemic species, and vulnerability to invasive organisms due to globalization-driven connectivity. Among these species, Aedes albopictus, a highly invasive vector of flaviviruses, has spread extensively across the RPI via human-mediated dispersal, posing significant health and economic burdens. While the population structure and the degree of gene flow between mosquito populations can inform the dispersal pathways critical for disease vector management, the population genetics of Ae.

Complete mitogenome sequence of from Hawai'i Island.

We report the first complete mitogenome (Mt) sequence of (Diptera: Culicidae). The sequence was extracted from one adult from the Big Island of Hawai'i Island. The length of the Mt was 16,528bp with 78.

Field Evaluation of In2Care Mosquito Traps to Control Aedes aegypti and Aedes albopictus (Diptera: Culicidae) in Hawai'i Island.

Aedes aegypti Linnaeus and Aedes albopictus Skuse are vectors of dengue virus and responsible for multiple autochthonous dengue outbreaks in Big Island, Hawai'i. Control of Ae. aegypti and Ae.

Efficacy of systemic insecticides on the gall wasp Quadrastichus erythrinae in wiliwili trees (Erythrina spp.).

Background: Erythrina gall wasp (EGW), Quadrastichus erythrinae Kim, was first found on Oahu Island, Hawaii, in April 2005. Its rapid spread and infestation in wiliwili trees (Erythrina spp.) have brought an urgent need to suppress its population.

Application of an enzyme-linked immunosorbent assay for the analysis of imidacloprid in wiliwili tree, Erythrina sandwicensis O. Deg, for control of the wasp Quadrastichus erythrinae.

A monoclonal antibody-based enzyme-linked immunosorbent assay (ELISA) for the neonicotinoid insecticide imidacloprid was evaluated for its reproducibility, accuracy, and comparability to results from a conventional high-performance liquid chromatography (HPLC) for the analysis of imidacloprid in the endemic wiliwili tree (Erythrina sandwicensis O. Deg) found in dryland forests and landscapes in Hawaii. Imidacloprid was applied to these wiliwili trees in an attempt to control the newly introduced erythrina gall wasp, Quadrastichus erythrinae Kim.

Hot water immersion for surface disinfestation of Maconellicoccus hirsutus (Homoptera: Pseudococcidae).

Mealybug Maconellicoccus hirsutus (Green) adults, nymphs, crawlers, and eggs were tested for their susceptibility to hot water immersion at 47, 48, and 49 degrees C. Eggs inside ovisacs were found most tolerant with prolonged survival compared with other stages at all temperatures. Ovisacs required an average of 1.

Irradiation of Maconellicoccus hirsutus (Homoptera: Pseudococcidae) for phytosanitation of agricultural commodities.

Studies on the tolerance of pink hibiscus mealybug, Maconellicoccus hirsutus (Green), to ionizing irradiation were undertaken to determine the dose needed to disinfest commodities of this pest. Overall, radiotolerance of M. hirsutus was found to increase with maturity.
