Insecticide Resistance Evolution Negatively Affects the Fitness of Glover During Selection on Cotton Plants Under Laboratory Conditions.

The cotton aphid, Glover, is among the most economically significant sap-sucking insect pests, inflicting substantial economic losses worldwide. Insecticides such as thiamethoxam, bifenthrin, and flonicamid are commonly used to manage this pest, despite the inherent risk of developing resistance. In this study, we investigated the evolution of insecticide resistance in after continuous selection with thiamethoxam, bifenthrin, and flonicamid over more than ten generations in a controlled laboratory environment.

Cyantraniliprole-mediated transgenerational hormesis in the invasive tomato pinworm, Tuta absoluta.

Background: Hormesis, a biphasic dose-response phenomenon, is gaining recognition for its bioregulatory and practical implications. Invasive species present a critical context for studying hormesis, because sublethal population-level responses may facilitate establishment and spread, particularly when transgenerational effects are involved. The invasive South American tomato pinworm, Tuta absoluta Meyrick, a global agricultural pest, exemplifies this scenario.

Samia ricini: The promising large host eggs outclass Antheraea pernyi for rearing Trichogramma species.

Trichogramma, a globally recognized egg parasitoid, plays a pivotal role in the biological control of lepidopteran pests. However, its mass production relies heavily on the large eggs of the Chinese oak silkworm (Antheraea pernyi Guérin-Méneville, COS), which poses a limitation due to varying compatibilities among different Trichogramma species. This study investigates the potential of Eri silkworm (Samia ricini William Jones, ES) eggs as an alternative host by evaluating the performance of 6 Trichogramma species (T.

Diapause-induced transgenerational performance of Trichogramma ostriniae exploiting Corcyra cephalonica eggs.

Background: Diapause induction is a crucial method widely used for storage in commercial production of Trichogramma, which may affect biological traits of parasitoids significantly. However, whether the diapause-induced biological changes persist across generations has never been determined. In a preliminary experiment, we found that diapause-exposed females of Trichogramma ostriniae showed a positive effect interpreted as increased oviposition.

Transgenerational effects of heavy metal contamination on two Trichogramma egg parasitoids and potential impacts on biological control.

The increased basic knowledge of biological control agents' bio-ecology under environmental stress provides useful information for optimizing integrated pest management. With an increasing awareness of cadmium (Cd) pollution in agroecosystems, this study evaluated the transgenerational effects and host preference of two widely distributed and utilized egg parasitoids, Trichogramma dendrolimi and Trichogramma japonicum through bottom-up effects mediated by Cd. The host rice moth Corcyra cephalonica was reared on a diet with 20 mg/kg Cd exposure for 1 generation; eggs were collected, and then exposed to Trichogramma.

Proactive Resistance Management Studies Highlight the Role of Cytochrome P450 Genes in the Resistance of Against Tetraniliprole.

The diamide insecticide tetraniliprole is a valuable tool for managing major insect pests like the invasive tomato pinworm, (Meyrick). However, the mechanisms underlying tetraniliprole resistance, as well as its associated fitness costs, remain unclear.

RNAi-mediated silencing of CYP4G15 correlates with altered transmission of barley yellow dwarf virus in Sitobion avenae (Fabricius).

Insect-borne plant viruses have emerged as major threats to crop production, and the genes of vector insects involved in viral transmission are crucial for effective viral control. However, few studies have identified and functionally validated these genes. A previous study suggested that the aphid protein CYP4G15 interacts with the barley yellow dwarf virus (BYDV; Luteoviridae: Luteovirus) virion in vitro.

Nanocarrier-mediated RNAi of and enhance susceptibility of invasive tomato pest, to cyantraniliprole.
