Although Nesidiocoris tenuis is highly effective as a biological control agent, it can also damage tomato plants due to its zoophytophagous behavior. When N. pierces the stems and petioles of with stylets, triggers callose deposition subsequent cell death, resulting in blocked nutrient transport, floral abortions, or wilting tender shoots. Recently, has been shown that exposure green leaf volatile (Z)-3-hexenyl propanoate [(Z)-3-HP] activates defensive mechanisms, including regulation genes involved synthesis degradation callose. In this study, conducted under greenhouse conditions, we tested hypothesis caused by could be reduced exposing (Z)-3-HP through polymeric dispensers. Tomato exposed non-exposed were inoculated tenuis. established both groups no significant differences between two treatments. However, hypothesized, was significantly lower (Z)-3-HP. Gene expression analysis salicylic, jasmonic, abscisic acids, along histochemical staining methods, used compare responses infested solely versus those Our findings confirm influence on differential activation treatments (Z)-3-HP-exposed plants. These results pave way for improved management enhancing plant's defenses based inter-plant communication.

Abstract The generalist predator Nesidiocoris tenuis , an effective biological control agent of numerous pests the tomato crops, can also trigger plant defence mechanisms (direct and indirect) due to its phytophagous behaviour. In southern Europe, is frequently released in greenhouses invasive pest Tuta absoluta sometimes combined with another biocontrol agent, egg parasitoid Trichogramma achaeae . this study, using olfactometer bioassays, we showed that modification volatile chemical profile induced by feeding activity mirid made plants more attractive T. achaeae, both absence presence eggs or larvae. This result was discussed relation difference observed among profiles organic compounds punctured N. without combination infestation. We found a few ( e.g. β -pinene myrcene) could play role foraging behaviour scenario Overall, our data support emerging idea ecological addition predatory activity, making crops resilient against attack pests, including absoluta.

Abstract Biological control, which uses natural enemies to reduce pest populations, is a non-polluting powerful method manage impacts of (invasive) pests. Currently, polyphagous mirid predators are increasingly used in commercial, augmentative biological control. Information about their foraging behaviour essential, especially if one intends use several for control or more pests crop, detect negative intraguild effects occur. We studied case predation (IGP) involving predator, Macrolophus basicornis , the worldwide invasive South American tomato leaf miner Tuta absoluta and explored how this predator deals with prey parasitized by Trichogramma pretiosum . Behavioural observations show that M. contacted significantly fewer old, eggs T. than recently ones. Olfactometer tests revealed could smell differences between volatiles leaves infested different quality locate suitable prey. They preferred from leaflets unparasitized above leaflets, and, moreover, over 5-day old eggs. When parasitoids together should be introduced days before prevent high levels IGP.

Abstract Mirid predators are increasingly used in biological control of multiple greenhouse crops pests. However, due to great morphological similarity and tiny body size, some mirid have been largely confused with their allied species. Nesidiocoris tenuis Reuter as a commercial predator was poppiusi Carvalho China. To evaluate the biocontrol potential N. poppiusi, its traits functional response Bemisia tabaci Gennadius were studied compared under laboratory conditions. The results showed that no significant differences developmental times from first instar adult stages between 2 mirids fed on Corcyra cephalonica Stainton eggs observed, while had better population growth parameters than tenuis. Under condition prey, both female male lived significantly longer those It could lay 74.0 eggs, which higher (30.2 eggs). without couldn't complete development adulthood tomato, tobacco, muskmelon, cabbage leaves, however, tobacco tomato more suitable other plants.
