“…Further, since a presently recommended action threshold based on YSB moth catches in pheromone traps is about 25 moths per trap per week [24] which is apparently based on moth catch estimates correlated from Funnel trap, there is scope for locally refining the applicable threshold for moth catches if Delta traps are used, to factor in the differential moth catch efficiency. Further, since past estimates of economic benefit of pheromone-based mass trapping technology were apparently made with Funnel traps [13], there is scope to improve the cost competitiveness of mass trapping of YSB moths as an option, since replacing with Delta variants would obviously be both more efficient and only slightly costlier than Funnel trap, since similar benefit has been shown in the case of another Crambid-the sugarcane early shoot borer [26]. The present results have therefore opened up the good potential for trap design choice as a factor in promoting pheromone-based mass trapping strategy as promising eco-safe alternative to the use of synthetic chemical insecticides for YSB management.…”

The yellow stem borer (YSB), Scirpophaga incertulas (Walker), is a major pest of rice in Asia and pheromone trapping technology is emerging as a promising eco-friendly IPM tool for more sustainably managing this pest. To identify more efficient trap design so to maximize the efficiency of attracting and retaining the male moths in pheromone-based trapping system, a common methodology-based network study was taken up to compare the moth catches in alternative sex pheromone-baited Delta traps of varying attributes versus the commonly used Funnel (sleeve) trap at three major rice growing locations (Coimbatore, Tirurkuppam, Tirupathisaram) in Tamil Nadu, India within the same season during 2017-18. The results from the concurrent six week trap catch studies clarified that two superior Delta trap variants caught significantly more YSB moths than the funnel trap at all three locations. The moth catches were about 4-5 times greater in the normal size Delta trap (32x20x11cm) compared the Funnel traps, while even the smaller size Delta trap (22x12x7.5cm) caught nearly 2 times more moths than Funnel traps. The attribute of additional vents on the side roof of Delta traps was found to enhance the moth catch in Delta trap significantly. The relative moth catches among the five Delta trap variants versus Funnel trap at each location are also illustrated, along with results of pooled analysis over the locations, which confirmed the consistent superiority of Delta trap versions and the extra benefit from additional vents as trap attributes in enhancing the moth catches. The present results have shown the scope to enhance the impact potential of the improved Delta trap designs in monitoring and mass-trapping of YSB. The need for future population ecology R&D in linking the use of such improved Delta trap versions to fine-tuning the local action thresholds which are based on trap catches by relating to trapping efficiency as a factor is indicated.

“…For methyl eugenolbased fruit fly trapping, the use of cylindrical white jar traps in combination with vial-wick dispenser has been found promising, while for cucurbit vegetables, there is scope for alternative trap types, pheromone blend and lure dispenser deployment 2015;Divya et al, 2011;Sithanantham, 2011;Suganthy et al, 2014). Further, it has been clarified that while the sleeve (funnel) trap is still efficient for trapping noctuid moths like Helicoverpa, it is found to be clearly inefficient for the crambid moth-Scirpophaga incertulas in rice compared to the improved delta traps, with additional access vents (Delta-Plus), which are found to be also superior to both sleeve traps and water basin traps for Leucinodes orbonalis in brinjal (Prabakaran et al, 2017) and Chilo infuscatellus in sugarcane (Prabakaran et al, 2018).…”

With the discovery of insect pheromones in intra-species communication in insects several decades back, the R&D on deploying synthetic insect pheromones as mimics of these olfactory signals is being increasingly explored for eco-friendly management of insect pests in major Agri-horticultural and forestry ecosystems. The focus of this paper is on the twin dimensions of pheromone deployment, namely monitoring the pest/vector populations and their utility in mass trapping for population suppression. The relevant pheromone trapping systems R&D scenario in India is illustrated with outcomes mainly from our ongoing collaborative research. In particular, it has opened up the scope to identify more efficient pheromone trap design by clarifying that funnel/sleeve trap seems adequate to trap noctuid moths, while a modified Delta trap (Delta-Plus) is clearly superior for at least three Crambid moths, with focus on trap attributes to improve male moth arrivals and/ or minimize their escape tendency. The scope for integration of pheromone technology with biological control towards bio-intensive IPM is indicated. Further, the policy support environment and future requirements are also covered in this paper.
