“…Previous studies showed that coriander plants intercropped with carrot, tomato, cabbage, and eggplant had higher abundance and diversity of coccinellids species than their respective monocrops, likely as a result of the attractiveness, and suitability as food, of coriander flowers for adult ladybeetles. Coccinellids also have an innate attraction to volatiles from coriander at the vegetative stage . Thus, although we used coriander as a ‘reward’ plant for natural enemies, this aromatic plant can attract natural enemies via emissions of constitutive leaf and floral volatiles.…”

“…‘Verdão’, was used as a companion plant because previous studies have shown that coriander when intercropped with cabbage, tomato, carrot, eggplant, and rose plants attracts natural enemies – for example, lacewings (Chrysopidae), hoverflies (Syrphidae), and ladybeetles (Coccinellidae). Coriander emits volatiles throughout all vegetative stages, which are known to be attractive to natural enemies . In addition, coriander flowers provide a source of nutrient (nectar and pollen) to natural enemies .…”

“…Entomophagous coccinellids actively utilize olfactory cues associated with the prey odor (Francis et al 2004), aphid-infested plants (Ninkovic et al 2001;Togni et al 1 3 2016), or the combination of both (Jamal and Brown 2001). Mycophagous ladybirds showed strong preference to characteristic odors released by squash plants infected by powdery mildew showing that such cues can play important roles in ladybird foraging behavior (Tabata et al 2011).…”

“…Entomophagous coccinellid species regularly consume non-prey food such as pollen and nectar (Togni et al 2016), honeydew and plant parts (Giorgi et al 2009), and fruits and fungi (Triltsch 1997). These types of food are an important component of diets for many ladybirds as an additional source of energy and often necessary for the development (Lundgren 2009a).…”

The diet of entomophagous coccinellids is mainly based on aphids and other food sources such as pollen, nectar, or fungal spores. Knowledge of their foraging behavior on plants infected by powdery mildew and their survival on fungal spores is currently limited. In this study, we investigated the olfactory response of Coccinella septempunctata to odor emission of barley plants infected by powdery mildew and their survival on fungal spores in the presence or absence of aphids. Odors released by powdery-mildew infected plants were more attractive for ladybirds compared to those of uninfected controls. After 3 days, the survival rate of ladybirds feeding only on powdery-mildew spores was less than 50%, while for ladybirds feeding exclusively on Rhopalosiphum padi aphids, the survival rate was close to 90%. After 15 days, the highest survival rate (almost 80%) was observed for ladybirds feeding on plants with both aphids and powdery mildew. Molecular analyses confirmed the presence of fungal spores in ladybird guts when feeding either on powdery mildew or on a mixed diet. Our results provide new insights into foraging behavior of entomophagous coccinellids revealing the potential of powdery mildew to be utilized as important non-essential food in a mixed diet, but also its lethal effect if consumed alone.

BACKGROUND: Harmonia axyridis Pallas (Coleoptera: Coccinellidae) is an important natural enemy of aphids. Plant species and plant health conditions can affect the behavior of H. axyridis. To determine plant effects on this lady beetle, we examined beetle responses to four cover crops: coriander (Coriadrum sativum L., Apiales: Apiaceae), marigold (Tagetes erecta L., Asterales: Asteraceae), sweet alyssum (Lobularia maritima L., Brassicales: Brassicaceae), and alfalfa (Medicago sativa L., Fabales: Fabaceae). Our goal was to better understand this predator's ovipositional behavior in response to different plants and its olfactory response to the aphid-induced volatiles from these plants.RESULTS: We found that this lady beetle did not have any significant oviposition preference among the four plant species, but H. axyridis preferred to lay eggs on the lower surface of leaves, regardless of the plant species. H. axyridis females had a significant preference for aphid-infested marigolds, but were not attracted by any of the other three cover plants or marigolds without aphid damage. Compared to the uninfested marigold plants, the emission of 12 compounds significantly increased on the aphid-infested marigolds, and two of them were attractive to H. axyridis under suitable concentrations.CONCLUSION: H. axyridis did not show any significant oviposition preference among the four cover crops. Aphid-infested marigolds can attract H. axyridis. Indole and terpinen-4-ol mediated lady beetle attraction. These synomones have potential for manipulating populations of H. axyridis as a component of conservation biological control.
