In recent decades, greenhouse crops relevance increased due to the high demand for products outside their growing season, with tomato standing out as one of most cultivated crops. these production systems, insects and mites find optimal conditions development, achieving populations that affect Farmers usually control using chemical insecticides, which health workers consumers have negative effects on environment. Tomato suffer damage by lepidopterans hemipterans, among those known whiteflies (Hemiptera: Aleyrodidae) perform regular attacks, causing yield quality losses in final product. Currently, use zoophytophagous predators Miridae family, Dicyphini tribe, an alternative biological control, has intensified studies Tupiocoris cucurbitaceus (Spinola, 1852), a predator several species aphids found Uruguay.

The European earwig Forficula auricularia (L.) (Dermaptera: Forficulidae) is an omnivorous insect that considered a minor pest of stone fruit and key predator pests in pome orchards. In many orchards, earwigs are absent or low abundance due to broad-spectrum spray programs the slow recolonization rate earwigs. Orchards transition organic “selective” conventional often struggle achieve effective levels biological control, thus, may benefit from inoculating expedite their re-establishment. two-year study, we evaluated potential for mass trapping using rolled cardboard traps reduce damage provide augmentation fruit.

Whether nutrient availability interacts with induced resistance to alter plant chemistry and, consequently, the preference and performance of herbivores on plants remains unclear. We hypothesized that changing fertilizer inputs modulates responses by exogenous application defensive phytohormone methyl jasmonate (MeJA) against Tuta absoluta, a devastating pest tomatoes. found tomato grown at or 2-fold above optimal rates had higher content were more preferred T. absoluta females for oviposition better hosts their offspring. MeJA increased phenolic volatile emissions in plants, which correlated lower offspring performance.

Plants can respond to insect infestation and virus infection by inducing plant defenses, generally mediated phytohormones. Moreover, defenses alter host quality for vectors with consequences the spread of viruses. In agricultural settings, other organisms commonly interact plants, thereby that could affect plant-virus-vector interactions. For example, induced omnivorous insects modulate behavior. This study focused on tomato yellow leaf curl (TYLCV), a family Geminiviridae genus Begomovirus. It is transmitted in persistent circulative manner whitefly Bemisia tabaci Gennadius (Hemiptera: Aleyrodidae), posing global threat production.

Intracellular bacterial endosymbionts of arthropods are mainly transmitted vertically from mother to offspring, but phylogenetically distant insect hosts often harbor identical endosymbionts, indicating that horizontal transmission one species another occurs in nature. Here, we investigated the parasitoid Encarsia formosa -mediated endosymbiont Rickettsia between different populations whitefly Bemisia tabaci MEAM1. was successfully positive MEAM1 nymphs ( R + ) into E. and retained at least for 48 h adults. Fluorescence situ hybridization (FISH) visualization results revealed ovipositors, mouthparts, digestive tract adults get contaminated with .

Further phylogenetic analyses had high fidelity during whiteflies parasitoids. Our findings may help explain why bacteria so abundant suggest that, some shared same parasitoids, be maintained transmission.

This provides signal of plant-plant competition induces rapid plant growth while inhibiting defence against biotic stress, two interlinked responses designated as shade avoidance syndrome (SAS). Consequently, SAS influence plant-herbivore interactions that could cascade to higher trophic levels. However, little is known about how expression tritrophic interactions.
