Silana farinosa (Boheman), commonly known as curry leaf tortoise beetle, is a coleopteran pest of curry leaves and some other plants belonging to the Rutaceae family. It is an emerging major pest of curry leaves in India that can cause severe defoliation to the crop. A female lays an average of 5.00 + 0.52 ootheca in her lifetime with a mean of 14.00 + 0.33 eggs in it. The average duration of the egg stage was 5.30 + 0.15 days, the grub stage was 16.80 + 0.29 days, the pupal stage was 5.00 + 0.21 and the adult stage was 81.10 + 0.80 days.

A biology study of Rhynocoris marginatus revealed that eggs of this species had a length of 2.65mm and breadth of 0.72mm, incubated for 8.07 days with an average 89% hatching rate. Average durations of first to fifth nymphal instars were 9.3, 9.5, 8.25, 11.4 and 19.45 days, respectively. The size of nymphs increased with successive nymphal instars with the first instar of 2.02 mm in length and the fifth instar being 9.4 mm in length. The average nymphal developmental period was 57.9±2.5 days. Female adults were easily distinguishable due to their broader size measuring a length of 15.2 mm and abdominal width of 5.92 mm, while male adults measured 12.3 mm in length and 4.2 mm in abdominal width. The sex ratio was female-biased (0.89:1). Pre-oviposition, oviposition and post-oviposition period lasted for 12.9, 44.6 and 5.6 days, respectively. Fecundity was 279±48.2 with an average of 45.5 eggs per batch. Female adults survived (63.1 days) more than males (42.1 days). Total generation time was found longer in females (129.3 days) than in males (108.8 days). Keywords: Reduviid bug, Morphometrics, Rhynocoris marginatus

The observations were recorded at Sardarkrushinagar, Gujarat during 2021 at fortnightly intervals in field from 1st Standard Meteorological Week (SMW) to 52nd SMW. The damage due to Betousa stylophora Swinhoe ranged between 0.80 and 48.8 percent with its peak (48.8% twig damage) in the 35th SMW, while the leaflet damage due to leaf rolling caterpillar ranged between 0.11 and 12.48 percent and exhibited its peak (12.48%) during the 31st SMW. In the case of bark eating caterpillar, the infestation ranged between 2.00 and 10.00 percent branch damage and reached its peak level (10.00%) during 26th SMW. Commencement of aphid appearance was recorded from 15th SMW with 0.02 aphid index, which reached its first peak (2.78 index) during 24thSMW and second peak (1.12 index) during 31st SMW. Physical factors viz. minimum temperature (MinT), morning relative humidity (RH1), evening relative humidity (RH2), rainfall (RF) and bright sunshine (BSS) established significant correlation with ‘r’ value of 0.521**, 0.578**, 0.887**, 0.605** and -0.665**, respectively with gall forming black caterpillar. The infestation of leaf rolling caterpillar established significant correlation with MinT (r= 0.592**), RH1 (r= 0.636**), RH2 (r= 0.883**), wind speed (WS) (r= 0.395**), RF (r= 0.521**) and BSS (r= -0.770**). The activity of bark eating caterpillar established significant positive correlation with physical factors viz., MinT (r= 0.436*), RH2 (r= 0.404*) and WS (r= 0.663**) whereas, aphid showed positive association with MinT (r= 0.588*), RH1 (r= 0.424*), RH2 (r= 0.385*) and WS (r= 0.824**).
