“…However, the ratio of Chl a/b showed a significant decreasing trend with increase in aphid infestation grades in our study, which is similar to the result of greenbug ( Schizaphis graminum Rondani ) damage in wheat [ 38 ]. Dai et al (2009) observed that significant reduction in Chl a, Chl b and carotenoid contents were found in Hypericum sampsonii plant damaged by thrips tabaci [ 39 ]. Differences in reflectance between healthy and stressed vegetation due to changes in Chl a and b levels have been detected in the green peak and along the red-edge spectral region of 690–750 nm [ 37 ].…”

Remote sensing can be a rapid, accurate, and simple method for assessing pest damage on plants. The objectives of this study were to identify spectral wavelengths sensitive to cotton aphid infestation. Then, the normalized difference spectral indices (NDSI) and ratio spectral indices (RSI) based on the leaf spectrum were obtained within 350–2500 nm, and their correlation with infestation were qualified. The results showed that leaf spectral reflectance decreased in the visible range (350–700 nm) and the near-infrared range (NIR, 700–1300 nm) as aphid damage severity increased, and significant differences were found in blue, green, red, NIR and short-wave infrared (SWIR) band regions between different grades of aphid damage severity. Decrease in Chlorophyll a (Chl a) pigment was more significant than that in Chlorophyll (Chl b) in the infested plants and the Chl a/b ratio showed a decreasing trend with increase in aphid damage severity. The sensitive spectral bands were mainly within NIR and SWIR ranges. The best spectral indices NDSI (R678, R1471) and RSI (R1975, R1904) were formulated with these sensitive spectral regions through reducing precise sampling method. These new indices along with 16 other stress related indices compiled from literature were further tested for their ability to detect aphid damage severity. The two indices in this study showed significantly higher coefficients of determination (R2 of 0.81 and 0.81, p < 0.01) and the least RMSE values (RMSE of 0.50 and 0.49), and hence have potential application in assessing aphid infestation severity in cotton.

“…As those leaves continue to expand and emerge, evidence of thrips feeding becomes apparent as silvered areas on the leaf surface. This feeding damage reduces the plant's photosynthetic ability (Dai et al 2009) and ultimately reduces onion bulb size (Diaz-Montano et al 2010;Kendall & Capinera 1987;Shock et al 2013).…”

“…As observed by Anderson et al (1995), these changes often have been regarded as a relatively late mechanism of photosynthetic adaptation. Dai et al (2009) (Linderman) damage, while Heng-Moss et al (2003) stated that the total chlorophyll and carotenoid concentrations differed among Betta wheat isolines in response to aphid feeding. Rafi et al (1996) reported that susceptible plants have similar chlorophyll concentration levels as their respective non-infested plants after exposure to Diuraphis noxia (Mordvilko), whereas resistant plants infested with D. noxia had reduced levels of chlorophyll when compared with non-infested plants.…”

“…This abundance of insects affects the maximum reduction in the values of the F v /F m and DF=F 0 m ratios in both fern and lemon leaves. The substantial decrease in chlorophyll fluorescence parameters indicated that the primary mechanism for photosynthetic rate reduction in damaged leaves is via the interference of the photochemical efficiency at the initial stage of photosynthesis (Dai et al 2009). Velikova et al (2010) reported a significant reduction in the chlorophyll fluorescence parameters of herbaceous plants resulting from the feeding and oviposition of two pentatomids, Murgantia histrionica (Hahn) and Murgantia histrionica (L.).…”

The aim of this experiment was to determine plant responses to Coccus hesperidum L. infestation on two host plants. Groups of five lemon and five fern plants were colonised by various numbers of mobile C. hesperidum instar nymphs. After 6 months, all scale insect individuals were counted on each plant. According to the insect density, the plants were divided into a five-degree series. In all density classes of host plants tested, the infestation of scale insects decreased the chlorophyll and carotenoid content as well as the value of three indicators of photosynthetic activity. The strongest decrease in the analysed pigments was observed for the smallest abundance of insects (firstclass density) in lemon leaves and in second-class density in fern leaves. The strongest reactions of the chlorophyll fluorescence indicators were observed in density classes III and IV in the fern leaves and density classes IV or V in the lemon leaves. The reactions depended on the specific properties of plants and abundance of insects feeding on them.
