“…Research of [27] showed that essential oil of clove leaves inhibited the feeding of S. litura. According to previous researches, secondary metabolites modulate insect behavior [28,29]. Antifeedant activity stimulates specific feeding resistant nerves chemoreceptors on insect mouth parts that work synergistically with other receptors [25].…”

Many parts of the Calotropis gigantea plant are known to contain bioactive compounds, but leaves contain the most. This study aimed to determine the toxicity and antifeedant activity of C. gigantea leaves against Plutella xylostella. The study was carried out from November 2019 to July 2020. Toxicity was tested using the leaf dipping and spraying methods. Antifeedant activity was tested using a no-choice test and a choice test. Identification of the compound composition of the leaf extract of C. gigantea was carried out at the Integrated Research and Testing Laboratory, Gadjah Mada University. Extract toxicity data obtained were analyzed by Probit analysis. The results showed that the antifeedant activity of C. gigantea leaf extract a no-choice and with choice at each concentration had a significant effect on the consumption of P. xylostella larvae rations. The toxicity (LC50) of the leaf extract of C. gigantea to P. xylostella by the dipping method was 2,958 µgl-1 while the spraying application was 3.944 µgl-1. The composition of chemical compounds contained in the leaf extract of C. gigantea is saponins, alkaloids, flavonoids, tannins, phenols, terpenoids. With the composition of these chemical compounds, the leaf extract of C. gigantea has the potential as a source of vegetable insecticide compounds against P. xylostella.

“…Odour is one of the most important stimuli. Olfactory organs in the insects receive air-borne chemical stimuli (odours) that affect their behaviour (Su et al ., 2009; Phillips and Throne, 2010) and lead them to food sources (Ajayi et al ., 2015; Arnold et al ., 2015), partners (Tewari et al ., 2015) or places suitable for laying eggs (Barrer and Jay, 1980). Food odour is an evaporable substance or a mixture of substances emanated from a food source and spread by air (Olsson, 2001).…”

AbstractTribolium castaneum is one of the most economically important insects that damages stored products. The effects of several infested or uninfested raw feed materials (wheat bran, coarse wheat meal, corn feed flour), feed products (compound feed for pigs and for laying hens) and flour mixed with brewer's yeast on the food-searching behaviour of T. castaneum adults were studied in a total of 48 combinations. Preference and olfactometer tests revealed that all the tested uninfested and intraspecific infested substrates were significantly more attractive to T. castaneum than the control (represented by part of an arena or olfactometer arm without substrate). We determined that all infested substrates were 2–9 times more attractive than uninfested in the preference test, while in the olfactometer test, they were 3–8 times more attractive. In comparing the attractiveness of the infested and uninfested substrates, in both tests wheat bran was found to be the most attractive substrate to T. castaneum adults and coarse wheat meal the least. The results of the present study contribute to our knowledge of how raw feed materials and products influence the behaviour of T. castaneum and their susceptibility to infestation, and indicate the possible utilization of wheat bran in monitoring processes of T. castaneum in pest management programmes.

“…Identifying chemicals that act as communication signals between AG and BG herbivores is critical for revealing mechanisms behind AG and BG interactions. The emissions of nonanal and 2‐ethyl‐hexanol which elicited strong electrophysiological and behavioural responses can both be induced by herbivory (Liu et al., ; Yu, Zhang, Wu, Gao, & Guo, ) and each can elicit EAG responses by insect herbivores for locating host plants for feeding and/or oviposition (Ajayi, Balusu, Morawo, Zebelo, & Fadamiro, ; Pophof, Stange, & Abrell, ; Sole, Sans, Riba, & Guerrero, ). Our laboratory and field test results provide evidence that these chemicals elicited by BG B. collaris larval herbivory are sufficient to attract AG conspecific adults.…”

Root‐feeding larvae increase their performance by inducing leaf volatiles that attract above‐ground conspecific adults

1. Herbivore-induced changes in plant volatile emissions mediate above-belowground interactions by determining host plant colonization of different herbivores.By changing shoot-emitted volatiles, below-ground herbivores may use the plant to extend their capacity to interact with above-ground con-and heterospecifics.2. We investigated the attractiveness of Triadica sebifera plants infested by larvae of a specialist beetle or root-knot nematodes to above-ground herbivores. We then determined the contribution of leaf volatiles to the observed recruitment patterns using olfactometer experiments. We also identified volatiles through gas chromatography-mass spectrometry (GC-MS) and electroantennography, and conducted field experiments to confirm their effects.3. Leaf volatiles induced by the root-feeding larvae attracted above-ground conspecific adults in laboratory and field experiments, but repelled a heterospecific specialist weevil, whereas induction by root-knot nematodes had no effects on either. Greater leaf consumption by conspecific adults increased root nutrients, decreased root defences and facilitated root feeding larval performance. Thus, larvae and adults appear to manipulate their host plant, which increases aggregation above-ground and feeding below-ground. 4. Synthesis. The resulting colonization dynamics may shape the composition of plant rhizosphere and phyllosphere herbivore communities by enhancing conspecific establishment and reducing colonization by other herbivores. By modifying above-ground volatiles and above-ground herbivore behaviour, root feeders could mediate plant and leaf herbivore interactions and benefit via plant responses to above-ground feeding.
