“…Results for the influence of fertilizers on insect performance are often contradictory, indicating either a positive effect on the population, no effect, or a negative effect . The current research on M. spectabilis also responded differently to fertilization according to the genotypes/cultivars, suggesting that the relationships between plant fertilization and insect performance are more complex.…”

BACKGROUND: Several factors may degrade pastures, in particular, inadequate nutrient application and spittlebug attacks. Mahanarva spectabilis (Distant, 1909) (Hemiptera: Cercopidae), one of the species that occur in Brazil, is a limiting pest in forage production. This study analyzes the influence of fertilization with the macronutrients nitrogen, phosphorus and potassium (NPK) on the survival of M. spectabilis nymphs, and the effects of damage by nymphs and adults on the production, quality and regrowth capacity of the forages Brachiaria ruziziensis, Pennisetum purpureum and Digitaria sp. RESULTS: Fertilization of the forages differentially affected damage due to spittlebug herbivory. Attacks by nymphs and adults decreased chlorophyll content, plant regrowth and forage quality, and increased injury, regardless of fertilization. The availability of nutrients in the soil not only decreased fiber content, but also increased crude protein, chlorophyll content and regrowth, even when pest infested. Soil fertilization increased the capacity of forage plants to lessen, albeit not eliminate, the effects of injury by M. spectabilis. CONCLUSION: Forages in fertilized soil are more tolerant to attacks by M. spectabilis nymphs and adults.

“…Females need to obtain nutrients from the host plant that are essential for egg development and to choose a suitable host for offspring performance (Minkenberg & van Lenteren, 1986;Videla et al, 2006). Because females evaluate the quality of host plants by feeding (Minkenberg & van Lenteren, 1986;Scheirs et al, 2003;Facknath & Lalljee, 2005), perhaps they only show a preference for a particular host plant after they have feeding experience on it.…”

Herbivorous insects use highly specific volatiles or blends of volatiles characteristic to particular plant species to locate their host plants. Thus, data on olfactory preferences can be valuable in developing integrated pest management tools that deal with manipulation of pest insect behaviour. We examined host plant odour preferences of the tomato leafminer, Liriomyza bryoniae (Kaltenbach) (Diptera: Agromyzidae), which is an economically important agricultural pest widespread throughout Europe. The odour preferences of leafminers were tested in dependence of feeding experiences. We ranked host plant odours by their appeal to L. bryoniae based on two‐choice tests using a Y‐tube olfactometer with five host plants: tomato, Solanum lycopersicum Mill.; bittersweet, Solanum dulcamara L.; downy ground‐cherry, Physalis pubescens L. (all Solanaceae); white goosefoot, Chenopodium album L. (Chenopodiaceae); and dead nettle, Lamium album L. (Lamiaceae). The results imply that ranking of host plant odours by their attractiveness to L. bryoniae is complicated due to the influence of larval and adult feeding experiences. Without any feeding experience as an adult, L. bryoniae males showed a preference for the airflow with host plant odour vs. pure air, whereas females did not display a preference. Further tests revealed that adult feeding experience can alter the odour choice of L. bryoniae females. After feeding experience, females showed a preference for host plant odour vs. pure air. Feeding experience in the larval stage influenced the choice by adults of both sexes: for males as well as females reared on bittersweet the odour of that plant was the most attractive. Thus, host feeding experience both in larval and/or adult stage of polyphagous tomato leafminer L. bryoniae influences host plant odour preference by adults.

“…Nutrient application changes the host-plant morphology, biochemistry, and physiology, which improves nutritional conditions for herbivores (Bernays 1990), thus playing a key role on insects. Nitrogen (N) content is one of the most important performance limiting factors of herbivores (De Bruyn et al 2002;Facknath and Lalljee 2005;Kerpel et al 2006;Lu et al 2007;Lu and Heong 2009;Han et al 2014;Oliveira et al 2014;Rashid et al 2016aRashid et al , b, 2017. In the present study, survival rate of both nymph and adult BPHs was markedly higher on N-enriched plant than Ndeficient one, and it was almost double and triple for nymph and adult respectively.…”

“…Furthermore, regression analysis in this study clearly indicated that BPH nymphal duration was negatively associated with plant tissue content of N, SP, and TFS, but positively with Si. Some reports showed that N is essential for growth and development of different insects (Facknath and Lalljee 2005;Huberty and Denno 2006;Lu et al 2007). On the other hand, P and K inputs had no effect on nymphal duration of BPH.…”

Ecological fitness of brown planthopper, Nilaparvata lugens (Stål), to rice nutrient management

Introduction: The brown planthopper (BPH), Nilaparvata lugens (Stål) (Hemiptera: Delphacidae), is a notorious insect pest of rice. Nutrient supplementation can alter plant biochemical compositions which may indirectly affect on ecological fitness parameters of its insect pest. However, few findings are available on nutrient-induced ecological fitness of BPH and relationship of BPH fitness parameters with its host rice plant biochemical contents. Methods: We studied the main and interaction effects of nitrogen (N), phosphorus (P), and potassium (K) inputs on BPH fitness, as measured by the following variables: nymph survival, nymphal duration, adult body weight, and its survival. Brown planthopper fitness parameters were regressed as function of rice plant (Oryza sativa) biochemical composition. A completely randomized design with four replications in a factorial scheme was used considering N, P, and K levels as factors. Results: Nitrogen application to the host rice plants provided greater survival and enhanced body weight of BPH. The nymphal duration was found to decrease with N subsidy that caused shorter generation time of BPH. Nitrogenous compounds N and soluble protein (SP), total free sugar (TFS), and silicon (Si) content in rice plant tissue correlated strongly with all fitness traits of BPH. Nitrogen, SP, and TFS associated positively with BPH survival and body weight, while negatively with nymphal duration. In contrast, Si had negative correlation with BPH survival and body weight, but positive with nymphal duration. Phosphorus supplementation to host plant contributed to increase BPH body weight. Relationships of P with all parameters of BPH were weak except body weight which was highly significant and positive. Interaction between N and P inputs demonstrated significant effect on BPH body weight. Application of K had no significant effect on BPH survival and development. Regression analysis did not detect significant relationship of BPH fitness parameters with plant tissue content of K. Conclusions: The results suggest that BPH ecological fitness characters were improved after N and P fertilization to rice plants which are associated with biochemical content of rice plant. Therefore, N and P inputs should be used judiciously in rice cultivation to keep BPH ecological fitness potential at minimum level.
