“…Ants that attend aphids belong largely to the most evolved subfamilies Myrmicinae, Formicinae and Dolichoderinae (Tizado et al, 1993). Noteworthy contributions on the natural enemies of aphids in India were made by Rao (1969), Raychaudhuri (1978), Ghorpade (1981), Ghosh and Raychaudhuri (1982), Stary and Ghosh (1983), Agarwala and Ghosh (1988), Singh et al (1999), Joshi (2005), Dey and Akthar (2007), Akthar et al (2011), Chaudhary and Singh (2012), Joshi and Sangma (2015), Bhat and Bhagat (2017), Khan et al (2017), Bhat et al (2020), Kale et al (2020) and Maji et al (2023). In India, aphid-ant association has been mainly dealt with Gadiyappanavar (1970), Roy and Behura (1980), Kurl and Misra (1980), Datta et al (1982Datta et al ( , 1983, Devi and Singh (1986), Verghese and Tandon (1987), Devi et al (1987), Devi et al (2001), Bisht et al (2002), Joshi (2005), Kataria and Kumar (2013) and Rakshan and Ahmad (2015).…”

Purposive surveys were conducted at regular intervals in different districts of eastern dry zone of Karnataka (Zone 5) during the year 2021-22, to document the natural enemy fauna and the ant species associated with aphids. Out of 34 aphid species recorded, 16 species of aphids were preyed on by 14 species of predators belonging to Coccinellidae, Syrphidae, Hemerobiidae and Chamaemyiidae and seven species of aphids were found parasitized by eight species of parasitoids belonging to Braconidae. Predators belonging to Coccinellidae and Syrphidae were recorded more abundantly with six species in each family, preying on 12 and 10 aphid species, respectively. Among the aphid parasitoids, Aphidius spp. was the more abundant taxa. Eleven species of ants belonging to Formicinae, Myrmicinae and Dolichoderinae were found associated with 17 aphid species. Ants belonging to the genus Camponotus were found to be more abundant and associated with 10 species of aphids. A comprehensive list of predators, parasitoids and ants associated with different aphid species was put together during this study.

“…Thus, we designed laboratory experiments using rusty plum aphid, Hysteroneura setariae (Thomas), which is also an important pest of many crops, viz. rice, wheat, sugar cane, maize and soyabean crops (Kale et al 2020) [11] . The objectives of this study were (i) to determine how the adult male and female, C. transversalis respond to the increasing densities of aphid, H. setariae, (ii) the influence of this density-dependent prey consumption on their body-weight, and (iii) the impact of this prey consumption dependent body-weight on the fate of the aphidbiocontrol programme.…”

We investigated the influence of density-dependent aphid consumption on the body-weight of adult male and female ladybirds, Coccinella transversalis Fabricius when fed on aphid, Hysteroneura setariae (Thomas). This density-dependent prey consumption in terms of functional response seems to modulate the body-weight of adult ladybirds, which has a direct implication on the fate of aphid biocontrol. Hence, adult male and female ladybirds were fed on aphids at varying densities (10 to 200 aphids) and the magnitude of aphids consumed and their influence on the adult body-weight was recorded. The prey consumption increased with an increase in aphid density and the aphid consumption pattern exhibits a Type II response. This simultaneously affected the body-weights of adult male and female, C. transversalis, which increased from 0.59±0.08 to 2.72±0.35 mg, and 0.69±0.083 to 3.46±0.37 mg, respectively when fed on aphids at an increasing density from 10 to 200 aphids. Among adults, female was a more potent aphid-biocontrol agent, as it possesses a greater attack rate (0.8423 ± 0.18) and can handle prey in lesser time (0.1558 ± 0.02 hour or 9.35 ± 1.20 min), as compared to that of male ladybird. The density-dependent aphid consumption may directly affect the body-weight, as consumption of a greater number of aphids may lead to the increase in adult bodyweights, thereby making them better biocontrol agents in terms of quantitative aphid consumption. It is concluded that adult female C. transversalis possesses the potential for the biocontrol of H. setariae.

“…We found adults and larvae of C. transversalis preying on rusty plum aphid, Hysteroneura setariae (Thomas) infesting creeping bluegrass, Bothriochloa insculpta (Hochst.). This aphid is a cereal pest, attacking rice, wheat, sugar cane, maize and soya bean crops on the Indian sub-continent (Kale et al 2020). In a banker plant system, H. setariae reared on grasses, can be used as a non-pest prey to build-up ladybird populations (Rattanpun 2017).…”

Aggregation of conspecific predators sharing a common prey, influences their bodyweights. We investigated the influence of intraspecific competition of adult ladybirds of Coccinella transversalis Fabricius on their bodyweight feeding on rusty plum aphid, Hysteroneura setariae (Thomas). Adult males and females consumed a significantly greater number of aphids with increase in predator-density, however, the aphid-consumption per predator declined with this increase. The weight gain per predator also decreased linearly with increase in the density of both male and female predators. This indicates that the weight-gain of the predator is a function of the prey consumed. The searching efficiency decreased with increase in predator density due to mutual inference. The mutual interference constants for adult male and female ladybirds were −0.419 and −0.546, respectively. The females consumed a greater number of aphids than males. The killing power of the ladybird denoted by the k-value increased curvilinearly with increase in predator density. We conclude that prey consumption is a function of body size and that the offspring of those that aggregate at low densities in prey-rich habitats develop into large adults.
