Impact of Environmental Microparticles on Insect Olfaction

Environmental Toxicology, EarlyView.
ABSTRACT Terrestrial insects underpin key ecosystem services, including pollination, herbivory regulation, decomposition, nutrient cycling, and disease control. These functions depend on chemical communication that guides insects to food, mates, hosts, shelters, and oviposition sites while helping them avoid threats.

Substrate promiscuity of key resistance P450s confers clothianidin resistance while increasing chlorfenapyr potency in malaria vectors

Cell Reports
Summary: Novel insecticides were recently introduced to counter pyrethroid resistance threats in African malaria vectors. To prolong their effectiveness, potential cross-resistance from promiscuous pyrethroid metabolic resistance mechanisms must be ...

Pyrethroid Resistance in a Japanese Colony of the Housefly

Journal of Pesticide Science, 1984
1983年夏, 栃木県益子の豚舎において, ペルメトリン空間噴霧によるイエバエ防除効果が劣化してきたという報告を受け, 同年9月に確認のための現地試験を行なった. 薬剤処理前と後において, 各種方法によりイエバエ成虫数の推移ならびにノックダウン状態からの蘇生率を調査して比較したところ, 明らかに防除効果が著しく低いことがわかった. このハエを実験室に持ち帰り, 増殖後そのまま, または薬剤で2, 3回淘汰後, 各種ピレスロイド剤, p, p′-DDTおよび有機リン剤に対する感受性を局所施用法でしらべた. 対象には標準的感受性系統の高槻系を供試した.

Reconsidering the importance of Metopolophium dirhodum (Walker) (Hemiptera: Aphididae) as a crop pest

Agricultural and Forest Entomology, EarlyView.
Four‐year field monitoring and laboratory studies revealed M. dirhodum occurs regularly in barley with high reproductive potential and extended adult longevity. Populations peaked during vulnerable crop stages, creating optimal conditions for BYDV transmission during critical infection windows. M.

Laboratory and experimental hut evaluation of mosquito net and indoor residual spray (IRS) insecticides for improved malaria control [PDF]

Since the start of Roll Back Malaria (RBM) in 1998 funding for malaria control has increased dramatically, resulting in the current peak of $2.5billion spent on global malaria control annually.

Toward a Politics of (In)Fertility: Reproductive Debility in Africa

American Anthropologist, EarlyView.
ABSTRACT Sub‐Saharan Africa has some of the highest estimated rates of infertility or involuntary childlessness in the world, leading epidemiologists to refer to parts of the region as the “infertility belt.” The medicalization of infertility and the situating of assisted reproductive technologies (ARTs) as the treatment for infertility have siphoned ...

Low Rates of Kaolin in Different Application Periods Reduce Diaphorina citri Population and Huanglongbing Incidence in Commercial Citrus Orchards

Journal of Applied Entomology, EarlyView.
ABSTRACT Huanglongbing (HLB) is the most destructive citrus disease worldwide, and it has been disseminated by the Asian citrus psyllid Diaphorina citri, the vector of the causing agent Candidatus Liberibacter asiaticus. Although processed kaolin reduces psyllid infestation, long‐term field data from commercial orchards are limited.

Assessment of Salinity Tolerance in Lepeophtheirus salmonis Following Five Generations of Freshwater Treatment Selection

Journal of Fish Diseases, EarlyView.
ABSTRACT Non‐medicinal approaches for controlling sea lice (Lepeophtheirus salmonis) infestations, such as freshwater (FW) treatments, have been increasingly implemented to support more sustainable parasite control in aquaculture. This study evaluated the efficacy of FW treatment against sea lice under controlled experimental conditions and assessed ...
