Exploring marking methods for the predatory hoverfly Sphaerophoria rueppellii (Diptera: Syrphidae)

Insect Science, EarlyView.
As important pollinators and predators of aphids, hoverflies play an important role in ecosystems. This study focuses on identifying the best marking technique for the model species Sphaerophoria rueppellii that can be used to track hoverfly feeding and oviposition sites, evaluating three methods: rubidium (RbCl), fluorescein, and fluorescent dusts ...

Development and Reproduction of Nesidiocoris tenuis Reuter (Heteroptera: Miridae): The Effect of Temperature, Origin and Food

Entomologia Experimentalis et Applicata, EarlyView.
Nymphal development took longer at 25°C than 30°C, and the Greek N. tenuis population developed more slowly than the commercial population. Nymphs clearly preferred E. kuehniella eggs over Artemia sp. cysts when both were offered equally. Egg production increased at 30°C, while female longevity declined.

L925I mutation in the Para-type sodium channel is associated with pyrethroid resistance in Triatoma infestans from the Gran Chaco region [PDF]

, 2014
Background: Chagas' disease is an important public health concern in Latin America. Despite intensive vector control efforts using pyrethroid insecticides, the elimination of Triatoma infestans has failed in the Gran Chaco, an ecoregion that extends over

Developmental expression of Ap‐Vas proteins in aphids and flies reveals their evolutionary roles in insects

Insect Molecular Biology, EarlyView.
Duplication of vas genes is universally observed in aphids, and phylogenetic analysis indicates that this event predates the divergence of Aphididae and Phylloxeridae. Ap‐vas1 is germline‐specific, whereas Ap‐vas2–4 exhibit somatic expression, indicating functional divergence during aphid embryogenesis.

Life history parameters of Trialeurodes vaporariorum (Westwood) (Hemiptera: Aleyrodidae) at different environmental conditions on two bean cultivars [PDF]

Life-history parameters of the greenhouse whitefly Trialeurodes vaporariorum (Westwood), an important pest of bean crops in Colombia, were determined in environmental control chambers on two dry bean (Phaseolus vulgaris) cultivars (cv.).

Unsuccessful Cassava Brown Streak Disease (CBSD) evaluation attempts in western Democratic Republic of Congo and implications with cassava root necrosis disease (CRND) etiology [PDF]

, 2020
Open Access ArticleCassava brown streak disease (CBSD) is the second most important virus disease after Cassava mosaic disease (CMD), infecting cassava (ManihotesculetaCrantz) in Africa. The disease is caused by two distinct viruses, Cassava brown streak

First record of Encarsia formosa Gahan, an aphelinid parasitoid of greenhouse whitefly from India and its dynamics on tomato grown under protected environment

Journal of Biological Control, 2018
Greenhouse whitefly, Trialeurodes vaporariorum (Westwood) is a key pest of tomato under protected environment in Himachal Pradesh. Recently, an aphelinid parasitoid, Encarsia formosa Gahan was observed to parasitize T. vaporariorum in mid-hill regions of

Feeding Preference and Foraging Behaviour of Eriopis connexa on Two Aphid Species

Journal of Applied Entomology, EarlyView.
ABSTRACT Aphids are phloem‐feeding insects that cause both direct and indirect damage to crops, reducing agricultural productivity. Among the available pest control strategies, biological control using natural enemies is a sustainable and effective approach. The ladybird Eriopis connexa (Germar, 1824) is a generalist predator known for its voracity and

Efficiency of Using Macrolophus nubilus H.S. for Protecting Tomatoes from Major Pests in the Greenhouse Conditions of South Kazakhstan

AGRIVITA Journal of Agricultural Science, 2021
Since 2015, the greatest harm to greenhouse vegetables in Kazakhstan has been caused by a previously unknown pest of nightshades – the South American tomato moth (Tuta absoluta) and the greenhouse whitefly (Trialeurodes vaporariorum).
