Species of the genus Aulacophora Chevrolat, 1836 from Southern part of
Bangladesh had been intensively studied in the field and in the Taxonomic
Lab of Patuakhali Science and Technology University during the period from
July, 2018 to June 2019 which caused serious damage to cucurbits. The

... Aulacophora lewisii Baly (Coleoptera: Chrysomelidae) is an important pest of the genus Luffa (Yong, 1993;Lewis and Metcalf, 1996;Abe et al., 2000;Abe and Matsuda, 2005). The insect also feeds on towel gourd, bitter gourd, and other cucurbitaceous plants (LiYun et al., 2009;Sarker et al., 2019). The insect feeds on cucurbitaceous plants due to presence of four cucurbitacins (B, E, I, and E-glucoside) (Abe et al., 2000). ...
... The first to fourth instars feed on the young roots, while adults consume leaves and flowers of the plant and causes economic damage, if their populations are not controlled (Dilipsundar et al., 2022). The insect is widely distributed in India, Bangladesh, Pakistan, China, Japan, Bhutan, Malaysia, Vietnam, and Taiwan (Ahmad et al., 2013;Lee and Beenen, 2015;Sarker et al., 2019).

Aulacophora lewisii Baly (Coleoptera: Chrysomelidae) is an important pest of Luffa acutangula (L.) Roxb. (Cucurbitaceae) in India. Larvae of A. lewisii feed on the roots, while adults consume leaves of L. acutangula . In the current study, effects of three L. acutangula cultivars (Abhiskar, Debsundari, and Jaipur Long) on the life table parameters by age-stage, two-sex approach, and key digestive enzymatic activities (amylolytic, proteolytic, and lipolytic) of the larvae and adults of A. lewisii were determined. Further, nutrients (total carbohydrates, proteins, lipids, amino acids, and nitrogen content) and antinutrients (total phenols, flavonols, and tannins) present in the roots and leaves of three cultivars were estimated. The development time (egg to adult emergence) was fastest and slowest on Jaipur Long (31.80 days) and Abhiskar (40.91 days), respectively. Fecundity was highest and lowest on Jaipur Long (279.91 eggs) and Abhiskar (137.18 eggs), respectively. The intrinsic rate of increase ( r ) was lowest on Abhiskar (0.0511 day ⁻¹ ) and highest on Jaipur Long (0.0872 day ⁻¹ ). The net reproductive rate ( R 0 ) was lowest on Abhiskar (23.32 offspring female ⁻¹ ). The mean generation time ( T ) was shortest on Jaipur Long (52.59 days) and longest on Abhiskar (61.58 days). The amylolytic, proteolytic, and lipolytic activities of larvae and adults of A. lewisii were highest and lowest on Jaipur Long and Abhiskar, respectively. The lower level of nutrients and higher level of antinutrients influenced higher larval development time and lower fecundity of A. lewisii on Abhiskar than other cultivars. Our results suggest that Abhiskar cultivar could be promoted for cultivation.
