While insect monitoring is a prerequisite for precise decision-making regarding integrated pest management (IPM), it time- and cost-intensive. Low-cost, time-saving easy-to-operate tools automated will therefore play key role in increased acceptance application of IPM practice. In this study, we tested the differentiation two whitefly species their natural enemies trapped on yellow sticky traps (YSTs) via image processing approaches under practical conditions. Using bag visual words (BoVW)...

Abstract InsectSound1000 is a dataset comprising more than 169000 labelled sound samples of 12 insects. The insect level spans from very loud ( Bombus terrestris ) to inaudible human ears Aphidoletes aphidimyza ). were extracted 1000 h recordings made in an anechoic box with four-channel low-noise measurement microphone array. Each sample wave-file 2500 kHz length, at 16 rate and 32 bit resolution. Acoustic recognition holds great potential form the basis digital sensor. Such sensors are...

Abstract An undersowing system with additional intercropping of flowering plants was assessed in field trials Germany and Japan to estimate regulating effects on pests possible negative white cabbage ( Brassica oleracea var. capitata ). In particular, we tested undersown wheat Triticum aestivum L.) plus sweet alyssum Lobularia maritima L. Desv.) intercropping. Counts the aphid species Brevicoryne brassicae (L.) Myzus persicae (Sulzer), as well related predators plants, were determined....

Abstract Monitoring of pest presence and population development in the crop during season is essential for integrated management. Although many tools, instance coloured sticky traps, have been developed, full advantage available information rarely taken into account decision‐making. The reasons behind include high workload practice but also poorly studied relationships between trap catches populations crop. Here, we investigate whether commercially traps can be used as tool to monitor...

Abstract Successful and efficient pest management is key to sustainable horticultural food production. While greenhouses already allow digital monitoring control of their climate parameters, a lack sensors hinders the advent systems. To close loop, systems need be enabled directly assess state different insect populations in greenhouse. The presented article investigates feasibility acoustic for detection greenhouses. study based on an extensive dataset recordings made with array...

Abstract The development and morphology of the immature phases Pachycrepoideus vindemmiae (Rondani, 1875) (Hymenoptera, Pteromalidae) are described from a laboratory rearing culture maintained on Ceratitis capitata (Wiedemann, 1824) (Diptera, Tephritidae) using microscopic techniques, including light scanning electron microscopy. surface chorion egg is granulated, micropyle occurs at anterior end. labrum first instar larva does not have sensilla, second to fourth larvae setae head. mature...

The European cherry fruit fly, Rhagoletis cerasi, is the major insect pest of sweet and tart cherries. Its management becoming increasingly difficult in many countries as formerly effective but broad-spectrum insecticides are removed from market. With objective identifying suitable environmentally safe alternatives, we investigated bait sprays containing two families plant-derived insecticides: azadirachtins (NeemAzal-T(®) NeemAzal-T/S(®) ) pyrethrins (Spruzit Neu(®) ).In 12 semi-field...

Parasitoid fitness strongly depends on the availability and quality of hosts, which provide all resources required for larval development. Several factors, such as host size previous parasitation, may affect quality. Because self-superparasitism induces competition among a female's offspring, it should only occur if there is an imperfect recognition self-parasitized hosts or advantage to self-superparasitism. Against this background, we investigated offspring production in Spalangia cameroni...

Abstract The tomato russet mite Aculops lycopersici has become a challenging pest in production the EU. number of available acaricides is low, and efficacy biological control limited. With this study, we aim to understand better unhindered dispersal dynamics develop method reduce on plants. To A. layered cultivation under practical conditions, first trial was carried out. confirmed that symptoms usually occur lower or middle third plants then move upwards It observed plants, for limited...

Alternative pest control systems such as companion plants are increasingly gaining importance owing to a reduced range of available synthetic insecticides and more rigorous regulation their use in the EU. Therefore, we evaluated effects Brassica vegetables grown with wheat on relevant pests, respective natural enemies harvest weight. Six trials were conducted white cabbage three Chinese between 2017 2021. We identified an overall aphid-regulating effect for Brevicoryne brassicae (L.) Myzus...

Abstract With the reduced availability of effective plant protection products, alternative control measures gain importance. Insect net covers are a promising tool in this regard, because they can reduce pest damage on crop by exclusion pests. However, as under practical conditions, most need to be removed several times during cycle manage weeds and apply fertilizers, complete pests is not always feasible. In addition, also have an impact natural enemies, microclimate, may cause direct due...

Abstract Aculops lycopersici (Acari: Eriophyoidea) is a pest in tomato cultivation worldwide. In recent years, the number of reports A. infestations have increased Germany. first half 2019, survey 50 producing farms was conducted to assess occurrence and impact this has on The participating represented ~ 3.5% 1448 Germany with protected production 2019. Total area considered 131.8 ha which corresponds 34% 385.63 year. presence reported by 33 surveyed farms, within last 5 years. Amongst these...
