“…Surprisingly, however, the study on the plants' sugars does not correlate with the abovementioned increase in P. oleae longevity when fed with glucose and fructose (and not with sucrose). On the one hand, despite the fact that E. plantagineum and L. stoechas present similar sugar compositions -that is low in glucose and fructose and high in sucrose (Gonzalez et al, 2016b) -they actually enhance anthophagous' longevity. On the other hand, R. raphanistrum, presenting opposing sugar characteristics to E. plantagineum and L. stoechas -that is high in sucrose and with low levels of glucose and fructose -did not contribute to the longevity of P. oleae.…”

“…The main claim advanced is that, along the lines of Paredes et al, (2013Paredes et al, ( , 2015, a ground cover of the plant species studied in this work does not benefit any of the generations of the olive moth and therefore their maintenance in olive groves is to be considered. This article advances critical knowledge for the implementation of conservation biological control strategies against P. oleae by showing that plants previously identified as valuable for beneficial insects (Gonzalez et al, 2016a(Gonzalez et al, , 2016bParedes et al, 2013;Porcel et al, 2017;Villa et al, 2016aVilla et al, , 2016b are not benefiting P. oleae.…”

Conservation biological control aims to enhance the efficacy of biological control agents, such as predators and parasitoids, by providing them access to key requisites, for example floral or other alternative food resources. However, the occurrence of floral resources in agricultural systems may have positive effects not only on natural enemies but also on the pests themselves. For this reason, we have studied in laboratory common Mediterranean plants as potential food resources for an important lepidopteran olive pest, the olive moth, Prays oleae. The effects of 15 wild flowering plants from olive grove ecosystems, and four sugars present in floral nectars, on key biological parameters of P. oleae (i.e. longevity, pre-oviposition and oviposition periods, fertility and fecundity) were evaluated. The three pest generations were analysed. Only few of the plants tested increased some reproductive parameters of the insect individuals compared to the water-fed controls, while sugars generally improved them. This could be due to a higher concentration of sugars provided by individual sugars than by flower nectar. These results indicate that, in general, P. oleae will not benefit from the availability of the floral resources tested.

“…Restricting the access of predators to nectar can reduce their survival and fitness considerably (Lundgren and Seagraves, 2011;Portillo et al, 2012;van Rijn and Wäckers, 2016). Feeding on D. carota flowers can selectively benefit some insects, such as the parasitoid Cotesia glomerata (Winkler et al, 2009), while some others such as the lacewing Chrysoperla carnea and the herbivore Pieris rapae (Lepidoptera: Pieridae) do not benefit (Winkler et al, 2009;Gonzalez et al, 2016). The nectar is accessible and dominated by glucose and fructose (Broussard et al, 2017) but A. bipunctata larvae did not benefit from D. carota flowers in this study.…”

A Floral Diet Increases the Longevity of the Coccinellid Adalia bipunctata but Does Not Allow Molting or Reproduction

Adalia bipunctata L. (Coleoptera: Coccinellidae) is a generalist aphidophagous coccinellid and an important natural enemy in many agroecosystems including orchards. Coccinellid species have been observed to consume non-prey food like nectar and pollen, but the value of these foods for A. bipunctata is poorly known. The objective of this study was to determine the effect of different prey and non-prey diets on A. bipunctata larval development and adult longevity and fecundity. Larval development was studied on three prey diets: The aphids Dysaphis plantaginea and Myzus persicae and Lepidopteran eggs of Ephestia kuehniella; five flower diets: Matricaria chamomilla, Daucus carota, Fagopyrum esculentum, Anethum graveolens, and Sinapis alba; four pollen diets from three plant species: Typha angustifolia, Malus pumila (two varieties) and A. graveolens; and 1 M solutions of three sugars: glucose, fructose, and sucrose. Adult longevity and fecundity were tested on one prey diet (E. kuhniella eggs), three flower diets (F. esculentum, A. graveolens, and S. alba); the same four pollen diets and three sugar diets with larvae; and finally a mixed diet of sucrose and A. graveolens pollen. A water-only (starvation) control was used for both larval development and adult longevity and fecundity. Adult lipid content was assessed as a measure of how non-prey food affects the ladybeetles' nutritional status. Larvae did not develop beyond the first instar on any of the non-prey diets, but they lived more than twice as long as on F. esculentum and sugar diets than on water. Sugar and flower diets improved A. bipunctata adult longevity (71-92 days and 10-66 days, respectively) over a pure pollen diet (6-7 days). Fecundity was nil on all non-prey diets, and within a normal range on E. kuhniella eggs. The results suggest that pure floral diets do not support A. bipunctata molting or reproduction, but flowering plants can prolong A. bipunctata larval survival and adults longevity considerably when prey are absent. Adults on sugar diets had high lipid content, indicating that sugar feeding can improve overwintering survival. The findings could be used in agroecosystem design, such as the composition of flower strips for optimal functional diversity.

“…Neuropterans were present but rare. However, F. vulgare was shown as a beneficial plant for the fecundity of Chrysoperla carnea (Neuroptera, Chrysopidae), which is an important agent of biological control (Gonzalez et al 2016). Current data on the insect diversity of F. vulgare allow considering it as a potential magnet species with further comparison between its entomofauna and that of the neighboring plants.…”

Insects provide key ecosystem services such as pollination, dung burial, soil enhancement, and pest control. Global insect decline requires restoration of the plant-insect mutualistic interactions. By using magnet plants, it is possible to supply beneficial insects with better resource availability and create more sustainable habitats. Current management practices recommend using Umbellifers (Apiales, Apiaceae) in restoration projects. However, analyses of the structure and dynamics of entomofauna associated with this plant family is needed to facilitate practical actions. Here the attention is focused on species composition and seasonal dynamics of beneficial insects associated with sweet fennel Foeniculum vulgare (Apiaceae, Umbelliferae) in Crimea. A 2-year sampling campaign identified 60 insect species from 40 genera across 20 families and four orders: Hymenoptera, Diptera, Coleoptera, and Neuroptera. These insects represented the groups such as social wasps, bees, ants, bumble bees, potter wasps, beetles, lacewings, mud daubers, tachinid flies, and hoverflies. Social wasps and hoverflies dominated in sample collections. Most of insects collected benefit ecosystems and provide essential ecosystem services. During fennel's flowering season, the number of visits by bumble bees, beetles, bees. and wasps decreased. Contrastingly, dipterans visitation increased towards the end of the season. Such trends might be explained with fennel's functional protandry, bias in nectar production between male and female flower stages, and insects' feeding preferences. F. vulgare attracts a diverse assemblage of beneficial insects and consequently can be recommended as a magnet species. When aiming to attract specific insect groups, the seasonal dynamics of fennel's associated entomofauna should be considered.
