Drosophila suzukii (Matsumura) is a species native to Western Asia that able pierce intact fruit during egg laying, causing it be considered crop pest in many countries. have rapid expansion worldwide; occurrences were recorded North America and Europe 2008, South 2013. Due this expansion, we modeled the potential distribution of using Maximum Entropy Modeling (MaxEnt) algorithm Genetic Algorithm for Ruleset Production (GARP) 407 sites with known worldwide 11 predictor variables. After 1000...

Spotted-wing drosophila, Drosophila suzukii Matsumura, was first established in Latin America Mexico 2011. The vinegar fly has since been detected 296 municipalities Argentina, Brazil, Chile, Mexico, and Uruguay. is polyphagous found on 64 host plants 25 families America, with most hosts also exotic species. In D. attacked by 14 species of parasitoid wasps the Diapriidae, Figitidae, Pteromalidae, which are promising native parasitoids for control pest. This article analyzes results from...

Drosophila suzukii (Matsumura) is an important pest of small fruits, which has been causing significant damage to commercial crops in North America, Europe, and South America. This mainly controlled with insecticide applications because its highly biotic potential polyphagy. However, studies conducted infested by D. have shown that this species attacked parasitoids may serve as effective biological controls for pest. The aim the current study assess lethal time (LT10 LT50) parasitism exposed...

ABSTRACT Bean weevil and maize can cause considerable damage to stored grains. These insects are mainly controlled with synthetic chemical insecticides, which may bring serious problems human environmental health. Therefore, this study aimed evaluate the efficiency of essential oil clove [Syzygium aromaticum (L.) Merrill & Perry (Myrtaceae) (origin: Bahia, season Sep.2014-Feb.2015)] in control S. zeamais A. obtectus under laboratory conditions. The was extracted through classic...

Spotted-wing Drosophila, Drosophila suzukii (Matsumura, 1931), is an economic pest of thin-skinned fruit crops. Its control has commonly been carried out through chemical methods. However, given the need to develop safer and environmentally friendly management alternatives, pupal endoparasitoid Trichopria anastrephae Lima stands as a potential biological agent. lack information on mass rearing this parasitoid limits its use. Thus, objective our study was provide that useful for T. using D....

A total of 12,540 ripe fruits belonging to 46 species in 25 plant families were sampled from either the trees or ground 6 municipalities state Santa Catarina, Brazil between 2002 and 2006 determine which fruit fly developed on various host plants. Each was weighed placed into a plastic flask filled with sterilized sand 7 cm deep, opening covered sheer fabric. The flasks kept under controlled conditions (25 ± 3°C, 70 10% RH 12h photophase). After d, pupae sifted transferred Petri dishes lined...

Understanding the seasonal dynamics inherent to non-crop host–fruit fly–parasitoid interactions is vitally important for implementing eco-friendly pest control strategies. This study assessed abundance and infestation levels of three fly species, Ceratitis capitata (Wiedemann), Anastrepha fraterculus Drosophila suzukii (Matsumura), as well related saprophytic drosophilids, their natural parasitism in a disturbed wild habitat characterized by hosts northwestern Argentina over 40 months....

Drosophila suzukii (Matsumura, 1931) (Diptera: Drosophilidae) is a widely distributed pest of soft-skinned and stone fruits that controlled mainly with pesticides. An alternative to the chemical control sterile insect technique (SIT), an ecologically friendly method management could be used against D. suzukii. The objective present study was evaluate effects gamma radiation on reproductive sterility, ovarian morphometry, quality parameters Full female sterility achieved at 75 Gy, while...

The development of a suitable artificial diet allows the performance laboratory studies with quality insects, reasonable quantity, throughout year. Diets influenced biological parameters and fertility life table Drosophila suzukii (Diptera: Drosophilidae). A (maize meal, glucose, yeast) C molasses, presented best results for D. .

Abstract Over the past few years, use of RNA interference (RNAi) for insect pest management has attracted considerable interest in academia and industry as a pest-specific environment-friendly strategy control. For success this technique, presence core RNAi genes functional silencing machinery is essential. Therefore, aim study was to test whether Neotropical brown stinkbug Euschistus heros main supply dsRNA could generate an efficient gene response. To do this, total mRNA all developmental...

Understanding the mechanisms associated with coexistence of competing parasitoid species is critical in approaching any biological control strategy against globally invasive pest spotted-wing drosophila (=SWD), Drosophila suzukii (Matsumura). This study assessed two resident pupal parasitoids, Trichopria anastrephae Lima and Pachycrepoideus vindemiae Rondani, SWD-infested fruit, disturbed wild vegetation areas Tucumán, northwestern Argentina, based on niche segregation. Drosophilid puparia...

The increased cultivation of olive trees in Rio Grande do Sul State and its potential production arouse the need to characterize assemblage insects groves, especially those with as pests. Therefore, insect fauna was sampled monthly for two years, canopy trees, using beat cloth, collection buds five municipalities Southern State. faunal indices analyzed were abundance, constancy, dominance frequency. caterpillar Palpita forficifera Munroe 1959 (Lepidoptera: Pyralidae) mealybugs Saissetia...

Ceratitis capitata (Wiedemann) and Drosophila suzukii (Matsumura) are two severe invasive pests widespread in all Argentinean fruit-producing regions. Both coexist with the Neotropical pest Anastrepha fraterculus northern Argentina. The northwestern region shelters major soft fruit Citrus producing exporting industries, which heavily affected by these dipterans. Eco-friendly strategies under assessment This study mainly assessed D. suzukii, C. capitata, A. temporal abundance variations their...

In order to replace chemical herbicides, which harm the environment and health, we seek sustainable methods control weeds. We remove a seed-beetle species, Acanthoscelides atrocephalus, from synonymy with modestus recognize it as potential bioagent for Aeschynomene denticulata A. indica. Belonging megacornis group of genus Acanthoscelides, its fine morphology was analyzed using high-resolution photography scanning electron microscopy. The species differs others based on integument...

The article addresses the current and future potential distribution of Drosophila suzukii (Diptera: Drosophilidae), commonly known as spotted wing (SWD). This invasive pest affects various fruit crops worldwide. Native to Southeast Asia, species has rapidly expanded due its high adaptability climates ability infest ripe fruits. SWD occurrence data were collected from multiple databases, pseudo-absences selected background area, climatic variables downloaded WorldClim. Random Forest algorithm...

Drosophila suzukii (Matsumura) is a relevant pest affecting berries and stone fruits globally, including in the Neotropical region, where its invasion was reported about decade ago. Despite chemical control being main management method for D. suzukii, data on insecticide susceptibility populations are scarce. Here, we assessed of three field-collected Brazilian to four insecticides (i.e., deltamethrin, permethrin, spinetoram, imidacloprid) contrasted this with standard...
