“…Drosophila suzukii infests ripening fruits and is able to develop on many soft-skinned and damaged fruit crops as well as wild host plants (Kenis et al 2016;Lee et al 2015;Poyet et al 2015;Stewart et al 2014). Multiple insecticide applications are often needed to prevent economic losses to crops (Farnsworth et al 2017;Mermer et al 2020;Van Timmeren and Isaacs 2013), increasing management costs. Moreover, crop systems are challenged by repeated reinvasions of adult flies from non-crop or untreated-crop habitats that provide refuge for D. suzukii populations throughout the year (Hennig and Mazzi 2018; Santoiemma et al 2019;Tonina et al 2018;Wang et al 2019b).…”

Asobara japonica (Hymenoptera: Braconidae), Ganaspis brasiliensis and Leptopilina japonica (Hymenoptera: Figitidae) are Asian larval parasitoids of spotted wing drosophila, Drosophila suzukii (Diptera: Drosophilidae). This study evaluated these parasitoids’ capacity to attack and develop from 24 non-target drosophilid species. Results showed that all three parasitoids were able to parasitize host larvae of multiple non-target species in artificial diet; A. japonica developed from 19 tested host species, regardless of the phylogenetic position of the host species, L. japonica developed from 11 tested species; and G. brasiliensis developed from only four of the exposed species. Success rate of parasitism (i.e., the probability that an adult wasp successfully emerged from a parasitized host) by the two figitid parasitoids was low in hosts other than the three species in the melanogaster group (D. melanogaster, D. simulans, and D. suzukii). The failure of the figitids to develop in most of the tested host species appears to correspond with more frequent encapsulation of the parasitoids by the hosts. The results indicate that G. brasiliensis is the most host specific to D. suzukii, L. japonica attacks mainly species in the melanogaster group and A. japonica is a generalist, at least physiologically. Overall, the developmental time of the parasitoids increased with the host’s developmental time. The body size of female A. japonica (as a model species) was positively related to host size, and mature egg load of female wasps increased with female body size. We discuss the use of these parasitoids for classical biological control of D. suzukii.

“…Most insecticides used to control D. suzukii act on the AChE receptors or the sodium 23 – 25 , 41 , 57 , 58 . Products that use a different mode of action can thus help avoid the emergence of resistance to such compounds 27 , 28 .…”

“…Although synthetic spinosyn-based insecticides are available for the control of D. suzukii , these products require a preharvest interval of 5 to 14 days 22 . However, frequent applications may be necessary to keep the population level low 23 – 25 , meaning that there is a risk of pests developing spinosad resistance if producers do not alternate with a different chemical class 26 , 27 . In addition, the cultivation of small fruits in major producing countries, such as Brazil, is carried out on small properties that use organic or low-residue practices, and where the use of synthetic substances is restricted or prohibited 28 .…”

The diverse flora of the Atlantic Forest is fertile ground for discovering new chemical structures with insecticidal activity. The presence of species belonging to the genus Baccharis is of particular interest, as these species have shown promise in pest management applications. The objective of this study is to chemically identify the constituents expressed in the leaves of seven species of Baccharis (B. anomala DC., B. calvescens DC., B. mesoneura DC., B. milleflora DC., B. oblongifolia Pers., B. trimera (Less) DC. and B. uncinella DC.) and to evaluate the toxicological and morphological effects caused by essential oils (EOs) on the larvae and adults of Drosophila suzukii (Diptera: Drosophilidae). Chemical analysis using gas chromatography-mass spectrometry (GC–MS) indicated that limonene was the main common constituent in all Baccharis species. This constituent in isolation, as well as the EOs of B. calvescens, B. mesoneura, and B. oblongifolia, caused mortality in over 80% of adults of D. suzukii at a discriminatory concentration of 80 mg L−1 in bioassays of ingestion and topical application. These results are similar to the effect of spinosyn-based synthetic insecticides (spinetoram 75 mg L−1) 120 h after exposure. Limonene and EOs from all species had the lowest LC50 and LC90 values relative to spinosyn and azadirachtin (12 g L−1) in both bioassays. However, they showed the same time toxicity over time as spinetoram when applied to adults of D. suzukii (LT50 ranging from 4.6 to 8.7 h) in a topical application bioassay. In olfactometry tests, 92% of D. suzukii females showed repellent behavior when exposed to the EOs and limonene. Likewise, the EOs of B. calvescens, B. mesoneura, and B. oblongifolia significantly reduced the number of eggs in artificial fruits (≅ 7.6 eggs fruit−1), differing from the control treatment with water (17.2 eggs fruit−1) and acetone (17.6 eggs fruit−1). According to histological analyses, the L3 larvae of D. suzukii had morphological and physiological alterations and deformations after exposure to treatments containing EOs and limonene, which resulted in high larval, pupal, and adult mortality. In view of the results, Baccharis EOs and their isolated constituent, limonene, proved to be promising alternatives for developing bioinsecticides to manage of D. suzukii.

“…Apesar dos avanços nas medidas de manejo integrado de D. suzukii (ANDREAZZA et al, 2017), o uso profilático de organofosforados, piretroides e espinosinas sintéticas ainda é a ferramenta mais adotada (GRESS; ZALOM, 2018;SANTOIEMMA et al, 2019;MERMER et al, 2020). Para mitigar esses efeitos, os óleos essenciais (OEs) podem ser uma alternativa ambientalmente segura frente aos sintéticos, pois possuem múltiplos modos de ação, como inibidores da acetilcolinesterase e do ácido gama-aminobutírico e ligantes dos receptores de octopamina (JANKOWSKA et al, 2017).…”

Drosófila-da-asa-manchada (Drosophila suzukii) é uma praga polífaga que ataca preferencialmente frutos de epiderme fina. Métodos de controle são demandados, uma vez que são escassos os produtos fitossanitários recomendados para essa praga no Brasil. Assim, o objetivo deste trabalho foi avaliar o efeito larvicida do óleo essencial (OE) de Rosmarinus officinalis (alecrim) e de seu constituinte majoritário contra larvas de D. suzukii, bem como determinar as alterações morfológicas em órgãos/tecidos. Grupos de 20 larvas foram introduzidos em tubos contendo papel filtro impregnado com OE de R. officinalis e eucaliptol (80 mg L -1 ). Esses produtos ocasionaram mortalidade larval (± 98,5%) e pupal (± 1,5%) e inibiram a taxa de pupação (100%). Além disso, no cérebro e na cutícula das larvas foram observadas degeneração vacuolar e alterações morfológicas a partir do uso de ambos os produtos. Este trabalho demonstra o uso de OE de R. officinalis e eucaliptol como bioinseticidas contra D. suzukii, representando uma alternativa aos inseticidas sintéticos para o controle dessa praga.
