“…Four sampling techniques were studied: leaf beating on a white plastic tray (LBPT) (35‐cm length × 30‐cm width × 5‐cm depth), direct counting (DC) of insects on both leaf surfaces (abaxial and adaxial), whole leaf collection in paper bags (WLCPB) and yellow stick trap (YST). These techniques were chosen because they are the most frequently used techniques for sampling sap‐feeding insects (Jasrotia, Nataraja, Harish, Dutta, & Savaliya, ; Moura et al, ; Pinto et al, ).…”

A standardized sampling plan is the starting point for developing a decision‐making system for pest control. Aphis gossypii (Hemiptera: Aphididae) is a destructive sap‐feeding pest on cotton worldwide. However, research addressing cotton cultivar, plant phenology and field size with the aim of developing a sampling plan for A. gossypii has not been done. Therefore, in this study, we developed a standardized sampling for A. gossypii as a function of these factors. To accomplish this, A. gossypii densities in four experimental cotton cultivars were sampled weekly during year one to determine the ideal aphid characteristic to sample (by individual or colony). During year one and two, A. gossypii densities were sampled weekly in the same cultivars to determine sampling unit, sampling technique and the number of samples for an A. gossypii sampling plan. Using the sample number determined, the sampling time was recorded for cotton field size of 1, 5, 10, 50, 100 and 150 ha in order to estimate the sampling cost. In cotton, the count of individuals was the best characteristic for the assessment of A. gossypii. Leaves of the most apical branches for the vegetative and reproductive cotton plant stage were the best sampling units. The best sampling technique was direct counting. The cotton cultivar did not affect the development of the sampling plan. The A. gossypii sampling plan involved the evaluation of 58 samples per zone and required 20 min (<0.35 min/sample) for the evaluation of these samples. However, the walking time between samples was the main factor responsible for the total sampling time and cost in cotton fields, and this factor strongly depends on the size of the cotton field.

“…Contrary to Karnal, trap type was the main factor and alone contributed 17.8 and 45.5 %, respectively whereas trap height contributed least towards the trap efficiency at Niphad location. Backward stepwise regression modelling indicated that Döring, 2014;Jasrotia et al, 2016;Perring et al, 2018;Holland et al, 2019). The possible reason for greater attraction to yellow colour is associated with young, senescing or infected foliage that tends to indicate higher availability of nutrients such as aminoacids (Hodge and Powell, 2010;Farnier et al, 2014).…”

Aim: To evaluate the efficiency of most effective trap among two types of sticky traps of, i.e., card or tray of two colours (yellow and blue) and their placement height within wheat crop for catching alate of R. maidis, the most abundant aphid species in selected locations. Methodology: Sticky card and tray traps of two colours; yellow and blue were placed at different heights within wheat crop and the effects of trap parameters (type, colour and height) were evaluated to determine the trapping efficiency of R. maidis alate. The traps were installed at two heights above ground level; 100 cm and 150 cm at Karnal and Ludhiana and at 60 cm and 120 cm above ground level at Niphad location. Alate aphid counts were recorded weekly to make comparisons. Results: The highest number of R. maidis alate were caught on yellow coloured sticky card traps placed within the crop canopy at 100 cm height above ground and the lowest on blue coloured sticky tray traps at 150 cm height above ground at Ludhiana and Karnal. At Niphad, the highest population was caught on yellow coloured sticky card traps placed at 60 cm height above ground and the lowest number on blue coloured sticky tray traps at 120 cm height above ground. Correlation analysis revealed that all three trap parameters (trap type, colour and placement height) were correlated with mean alate trap catches. Backward stepwise regression modelling indicated that trap type and placement height had a maximum influence on the R. maidis alate trapping. Interpretation: This study indicated that the yellow sticky card traps were most effective in catching R. maidis alate as compared to other tested traps.

“…However, the efficiency level is dependent on their color, which can differ for different pests. For example, for whiteflies and aphids yellow sticky board is effective, whereas for thrips species blue is reliably effective (Jasrotia et al 2016). The number of onion thrips from sticky boards and plant samples should be counted in the laboratory.…”

Thrips tabaci Lindeman is a cosmopolitan and polyphagous insect pest. It is known worldwide and recorded on more than 300 plant species. T. tabaci is a key pest of onion and several other crops, and its control is vital to the production and profitability of crops. If onion thrips population is not controlled, damage can reduce yield volume and quality. In addition to direct damage to the host plants, T. tabaci has been characterized as an asymptomatic vector of three devastating tospovirus species, such as Tomato spotted wilt virus, Iris yellow spot virus, and Tomato yellow ring virus. For this reason, several synthetic insecticides were used for control. However, these insecticides bring unwanted effects, like pesticide resistance, elimination of nontarget species, environmental pollution, and threats to human health. To solve the negative consequences of insecticides, biopesticides, such as plant secondary metabolites, entomopathogenic viruses, bacteria, fungi, and nematodes, have been recognized as effective alternatives. The use of plant-based insecticides and entomopathogenic control methods gained more attention in integrated pest management. Their strong side is lack of residues, saving beneficial insects and minimizing air and water pollution. Plant-derived compounds and entomopathogenic biological control agents offered a variety of biological modes of actions against onion thrips, such as repellency, feeding deterrence, anti-oviposition, fecundity deterrence, metamorphosis inhibition, and parasiting the host’s body.
