Evaluation of local movement of Bemisia tabaci MEAM1 and tomato severe rugose virus transmission to tomato plants using marked and unmarked whiteflies J. Appl. Entomol. (IF 1.9) Pub Date : 2023-11-02 Felipe Franco De Oliveira, Gabriel Madoglio Favara, Michele Carmo-Sousa, João Roberto Spotti Lopes, Jorge Alberto Marques Rezende
Tomato golden mosaic disease, caused by the tomato severe rugose virus (ToSRV), is one of the most serious tomato diseases. ToSRV is transmitted by the whitefly Bemisia tabaci MEAM1, from a wide range of hosts. Introducing ToSRV in commercial fields probably can occur by transporting the virus from distant locations. However, our hypothesis is that the inoculum causing epidemic development might be

The presence of native aromatic species in understorey plant communities predicts reduced infestation by olive fruit flies in olive orchards on Lesvos Island J. Appl. Entomol. (IF 1.9) Pub Date : 2023-11-02 Sophie R. Stattegger, Thomas Tscheulin, Mark C. Mescher, Thanasis Kizos, Consuelo M. De Moraes, Stefan Meyer
The olive fruit fly (Bactrocera oleae) (Rossi) is the most economically important insect pest in many olive cultivation areas worldwide. However, levels of infestation by this pest show remarkable variability, even among orchards in close proximity to one another. While the factors driving this variability remain uncertain, there is evidence that the presence of native plants species can influence

Differential effects of soil conservation practices on arthropods and crop yields J. Appl. Entomol. (IF 1.9) Pub Date : 2023-10-31 Elinor M. Lichtenberg, Ivan Milosavljević, Alistair J. Campbell, David W. Crowder
Many agricultural management tactics, such as reduced tillage, aim to promote biodiversity and ecosystem services. Responses to such tactics can be context dependent, however, and differentially impact (i) functional groups of service-providing organisms and (ii) crop yields. In canola (Brassica napus L., B. rapa L.) crop fields, we assessed how soil tillage and landscape context (amount of semi-natural

Evidence of a pheromone involved in the behaviour of Drosophila suzukii Matsumura (Diptera: Drosophilidae) J. Appl. Entomol. (IF 1.9) Pub Date : 2023-10-30 Itzel Lima, Eduardo Tadeo, María Remedios-Mendoza, María de Jesús Martínez-Hernández, Cesar Ruiz-Montiel
Recent findings have documented the importance of (Z)-11-octadecenyl acetate (cVA) in the melanogaster group as a sex pheromone that regulates several sexual and social behaviours. However, this pheromone is missing in Drosophila suzukii, thus posing the question of whether it could have been replaced by another compound similar to cVA. Olfactory responses of D. suzukii females and males to conspecific

Microhymenoptera in roadside verges and the potential of arthropod-friendly mowing for their preservation J. Appl. Entomol. (IF 1.9) Pub Date : 2023-10-29 Maura Haas-Renninger, Justus Weber, Isabel Felske, Thomas Kimmich, Michael Csader, Oliver Betz, Lars Krogmann, Johannes L. M. Steidle
The worldwide decline of insects is one of the major challenges for humankind. One of its main drivers is intensive farming, which reduces habitats and food resources for insect populations and causes direct mortality by pesticides. In addition, mowing of grassland poses another threat to insects, especially when it is done frequently, such as in roadside verges. Roadside verges comprise large areas

Organic fertility management in cotton Gossypium hirsutum L. fosters arthropod biodiversity and complements pest suppression J. Appl. Entomol. (IF 1.9) Pub Date : 2023-10-27 Muhammad Shahid, Muhammad Omer Farooq, Muhammad Razaq, Muhammad Adnan, Shayan Zahid, Altaf Hussain, Farhan Mahmood Shah
Research on economic, ecological and relative benefits from organic and conventional farming systems has gained significant importance. Organic farming increases species diversity, enhances biological control services, and thus complements sustainable pest management. However, published literature is scarce on cotton crops grown organically with respect to the abundance and diversity of biological

RNA interference-mediated silencing of NOA and V-ATPase subunit D genes results in deformities and mortality in Bactrocera dorsalis (Hendel, 1912) J. Appl. Entomol. (IF 1.9) Pub Date : 2023-10-27 Simranpreet Kaur, Sandeep Singh, Prashant Mohanpuria, Mohan Govindasamy, Gurupkar Singh Sidhu, Zhang Yue, Zhihong Li
The Oriental fruit fly, Bactrocera dorsalis (Hendel) is one of the five disastrous pests in the world with an economical significance. The guava germplasm resilient to fruit fly is not reported worldwide to date. The utilization of RNA interference (RNAi) approach can offer a promising alternative for fruit fly management in guava. The goal of our investigation is to evaluate the efficiency of dsRNA

Selectivity of acaricides to Neoseiulus barkeri (Hughes) (Acari: Phytoseiidae) J. Appl. Entomol. (IF 1.9) Pub Date : 2023-10-25 Daniel L. Silva, Jayrla E. D. Lima, Pedro V. L. Souza, José W. S. Melo, Jose Eudes de Morais Oliveira, Debora B. Lima
Neoseiulus barkeri Hughes has been used to control several pests, including the red palm mite, Raoiella indica Hirst. However, in some situations, the exclusive use of biocontrol agents is not sufficient to prevent the damage caused by pests. In these scenarios, the integration of chemical and biological controls is desired. For that purpose, the determination of selective acaricides, avoiding or reducing

Glycerin-based dispensers of fir oil reduce response of Asian citrus psyllid, Diaphorina citri, to citrus odours J. Appl. Entomol. (IF 1.9) Pub Date : 2023-10-18 Angela Chuang, Lukasz L. Stelinski, Lourdes Pérez Cordero, Carlos Andres Antolinez, Monique J. Rivera, Mamoudou Setamou, Lauren M. Diepenbrock
The Asian citrus psyllid, Diaphorina citri Kuwayama, transmits the bacterial pathogen associated with huanglongbing, a fatal citrus disease. Alternatives to insecticides for D. citri management are being explored, given the development of insecticide resistance and the lack of efficient biological controls. Essential oils as pest repellents have shown some efficacy in laboratory and field evaluations;
