ABSTRACT The present study unveils the intricate details on the morphology of thrips through optical, Field Emission Scanning Electron Microscopy (FE-SEM) and mitochondrial COI gene based molecular identification tools. The variation in the morphological characters viz., antennae (7-segmented with forked sensorium on 3rd, 4th segments), ctenidia (paired ctenidia was present in 5-8 abdominal segments laterally), pronotum (2 pairs of posteroangular setae) were observed in both Thrips tabaci and Thrips parvispinus, respectively. Similarly, ocelli colour (brown and red coloured), ocellar setae 2 and 3 pairs of ocellar setae on the head of T. tabaci and T. parvispinus, respectively; irregular reticulate striations on metascutum and medial striations are present in the metanotum of T. parvispinus; forewings with 6 distal setae in the first vein and 15 distal setae in the second vein in T. tabaci and forewings of T. parvispinus with complete rows of setae in the 1st and 2nd vein in T. parvispinus; abdomen with median dorsal setae present in the tergite of T. tabaci and presence of 6–12 discal setae in sternites III-VI segments, absence of discal setae on sternites II & VII in T. parvispinus were observed respectively. Further, FE-SEM studies revealed that similar type of sensilla viz., sensilla basiconica (SBI, SBII, SBIII), sensilla chaetica (SchI, SChII), sensilla trichodea (ST), sensilla campaniformia (SCa), and sensilla cavity (SCav) were recorded in both the species and variations were observed in length of above sensilla of T. tabaci and T. parvispinus. Additionally, Bohm bristles (Bb) and microtrichia (Mt) on the antennal surface contributed to a comprehensive understanding of their ultrastructural features. The molecular characterization revealed a single ~450bp nucleotide fragment with over 98% similarity for the confirmation of T. tabaci and T. parvispinus in concurrence with NCBI data”. was incorrect.

The variation in the morphological characters namely, antennae (7-segmented with forked sensorium on 3rd, 4th segments), ctenidia (paired ctenidia was present in 5–8 abdominal segments laterally), and pronotum (2 pairs of posteroangular setae) were observed in both Thrips tabaci and Thrips parvispinus, respectively. Similarly, ocelli colour (brown and red coloured), and the number of ocellar setae present in T. tabaci was two pairs. In T. parvispinus, ocellar setae pair III was small, arising on the anterior margin of the ocellar triangle. Irregular reticulate striations on metanotum and medial striations are present in the metanotum of T. parvispinus; forewings with six distal setae in the first vein and 15 distal setae in the second vein in T. tabaci, and forewings of T. parvispinus with complete rows of setae in the 1st and 2nd veins in T. parvispinus; abdomen with median dorsal setae present in the tergite of T. tabaci and the presence of 6–12 discal setae in sternites III–VI segments, and the absence of discal setae on sternites II and VII in T. parvispinus were observed, respectively.

3.1.2 Ocelli Colour and Setae

The results on the light microscopic study observed the head with peculiar brown ocelli (Figure 6e) and red ocelli (Figure 6f) in T. tabaci and T. parvispinus, respectively. The FE-SEM results exposed the ocellar setae more clearly than a light microscope. The number of ocellar setae present in T. tabaci and T. parvispinus were two and three pairs, respectively. Similarly, the size was larger in T. tabaci (43.15 ± 0.62μm) (Figure 6a&b) and smaller in T. parvispinus (22.56 ± 1.71μm) (Figure 6c&d).

3.1.2 Ocelli Color and Setae

The results on the light microscopic study observed the head with peculiar brown ocelli (Figure 2e) and red ocelli (Figure 2f) in T. tabaci and T. parvispinus, respectively. The FE-SEM results exposed the ocellar setae more clearly than a light microscope. The number of ocellar setae present in T. tabaci was two pairs. In T. parvispinus, ocellar setae pair III was small, arising on the anterior margin of the ocellar triangle. Similarly, the size was larger in T. tabaci (43.15 ± 0.62 μm) (Figure 2a,b) and smaller in T. parvispinus (22.56 ± 1.71 μm) (Figure 2c,d).

3.1.3 Pronotum and Reticulations

Both the microscopy techniques recorded two pairs (Figure 7a,b) and three pairs (Figure 7c,d) of posteroangular setae in the pronotum; the mean length was higher in T. parvispinus (38.94 ± 4.19 μm) compared to T. tabaci (22.56 ± 1.71 μm). Further reticulations (net like pattern or structure) were present on the metascutum with two pairs of median metanotal setae (Figure 8a,b) and metanotum without setae (Figure 8c,d) in T. tabaci and T. parvispinus, respectively. The above structure was not clear in the light microscope, and FE-SEM exposed the structure clearly.

3.1.3 Pronotum and Reticulations

Both the microscopy techniques recorded pronotum with two pairs of posteroangular setae (Figure 3a,b) and three pairs of posteromarginal setae in T. parvispinus and T. tabaci (Figure 3c,d). The mean length was higher in T. parvispinus (38.94 ± 4.19 μm) compared with T. tabaci (22.56 ± 1.71 μm). Further, reticulations (net like pattern or structure) were present on metanotum with two pairs of median metanotal setae (Figure 4a,b) and metanotum with long median setae (Figure 4c,d) in T. tabaci and T. parvispinus, respectively. The above structure was not clear in light microscope, and FE-SEM exposed the structure clearly.
