Propylea Dissecta

Abstract Propylea dissecta (Mulsant) (Coleoptera: Coccinellidae) is one of the most promising ladybird beetle against many sucking pests. Predation rates, developmental biology, life table, and field assessment of this ladybird were examined against mustard aphid, Lipaphis erysimi (Kalt.) (Hemiptera: Aphididae), on broccoli. Data on the life history were collected at 23 ± 1°C and 70 ± 1% RH and were evaluated using the two-sex, age-stage life table. Results showed that the two-sex, age-stage life table-based net reproductive rate (R0) was 11.264 ± 6.197 offspring. The adult females lived longer (33.8 ± 2.356 d) than the adult males (32.2 ± 0.841 d). The fourth instar consumed most of L. erysimi (113.97 ± 5.76) compared to the other larval stages of the predator. Male (1,821) and female (2,673) consumed more aphids than larvae. The net consumption rate was 741.78 ± 89.91 aphids. Other aphidophagous predators such as Coccinella septempunctata L., Micraspis discolor (F.), Coccinella transversalis (F.), and syrphid (Diptera: Syrphidae) were also noted in broccoli. Our research showed that inoculative release of 150 or 200 adults per 1,000 m2 for two times on broccoli achieved a significant decrease in aphids L. erysimi and Brevicoryne brassicae L. (Hemiptera: Aphididae) (>95%). The release rate of 150 adults per 1,000 m2 for two times may, therefore, be recommended to manage the aphid population on broccoli.

Abstract The study aimed to determine the effect of two aphid species; Lipaphis erysimi (Kaltenbach) and Aphis gossypii Glover (Hemiptera: Aphididae) on life table and demographic parameters of Hippodamia convergens Gu`erin-M´eneville (Coleoptera: Coccinellidae). The developmental period of all life stages of H. convergens was shorter when fed on L. erysimi. Net reproductive rate (Ro) was higher (159.85 offspring/individual) on L. erysimi, while it was 87.85 offspring/individual on A. gossypii. Mean generation time (T) was shorter (30.49 d) on L. erysimi than on A. gossypii (45.1 days). Values of the intrinsic rate of increase (r) and finite rate of increase (λ) were calculated as 0.166 days−1 and 1.181 days−1, respectively, on L. erysimi that were higher than on A. gossypii (0.099 days−1 and 1.104 days−1, respectively). Similarly, the survival rate was also higher when the predator was fed on L. erysimi. Overall, the findings suggest using L. erysimi as a better source of prey than A. gossypii for rearing H. convergens.

A two-sex life table is a useful tool for studying the fitness of predators. Previous studies of Orius strigicollis Poppius (Heteroptera: Anthocoridae) fitness have not been done on Pectinophora gossypiella (Lepidoptera: Gelechiidae) using a two-sex life table tool. This study reports the fitness of the minute predatory flower bug, O. strigicollis when feeding on the cotton pest P. gossypiella using a two-sex life table tool. Different densities (5, 10, and 15 eggs) of P. gossypiella eggs were used to calculate the feeding capacity and fitness of O. strigicollis in the laboratory at 28 °C ± 1, 75 ± 5% RH and 16:8 (L:D). The results concluded that O. strigicollis is an efficient predator of P. gossypiella. The maximum growth capacity of the predatory bug O. strigicollis was attained when it was fed on 10 and 15 P. gossypiella eggs. Furthermore, shorter generation and development time were also observed in the case of 15 eggs of P. gossypiella. These results suggest that O. strigicollis has considerable predatory potential and prefers feeding on P. gossypiella eggs than on the first instar larvae at the fourth instar or the female stage. Although the field potential of O. strigicollis is still unknown, this study will support future investigations in terms of field applications.

Basic biological attributes and feeding potential of three major predators viz., the seven spotted lady bird beetle <em>Coccinella septempunctata</em> Linnaeus and two syrphids <em>Episyrphus viridaureus</em> (Wiedemann) and <em>Betasyrphus isaaci</em> (Bhatia), of mustard aphid, <em>Lipaphis erysimi</em> were studied under laboratory conditions. The predators were multiplied on mustard aphids reared on mustard plants.<em> C. septempunctata, E. viridaureus </em>and<em> B. isaaci</em> completed their life cycle in 68.5± 6.5 days, 47±2 and 41±2, respectively. <em>Coccinella septumpunctata</em> completed the larval growth with four larval instars, while both the syrphids terminated the larval growth with three instars. Final instars of all the three predators were found to have highest predatory potential than the younger instars. <em>C. septumpunctata</em> was found to be the most dominant predator of mustard aphid with average lifetime consumption of 4312±537.74 aphids, followed by <em>E. viridaureus</em> (416.67±6.76 aphids) and <em>B. isaaci</em> (338±7.89 aphids). All the three predators have the potential to reduce the mustard aphids; however,<em> C. septumpunctata</em> has a maximum predatory potential with a longer life, which makes this species as an excellent bioagent of <em>L. erysimi</em> and further research on their utilization on a large scale should be undertaken.

AbstractLadybird beetle, Menochilus sexmaculatus (Fabricius) (Coleoptera: Coccinellidae), is biological control agent that predate the different aphid species. Both adults and larval stage of M. sexmaculatus feed on aphid species. In this experiment Life table and predation data were collected for M. sexmaculatus feed on four different aphid species Lipaphis erysimi, Myzus persicae, Aphis nerii and Diuraphis noxia. This experiment was conducted under laboratory conditions at 25±2°C, 60±5% RH and L14: D10 h. Different numbers of aphid were provided as a pray in petri dish. The pre-adult development duration of M. sexmaculatus was maximum when fed on M. persicae (12.18 d) and minimum on D. noxia (10.64 d). Similarly, male and female duration was maximum on M. persicae (26.7 d), minimum on L. erysimi (23.67 d) in male and in female maximum on D. noxia (28.00 d), minimum on A. nerii (24.33 d). Net reproductive rate (Ro) range from 117.9 on L. erysimi to 99.55 on M. persicae and intrinsic rate of increase (r) range was 0.21197 d−1 on A. nerii to 0.021559 d−1 on D. noxia. The finite rate of increase (λ) range was 1.240592 d−1 on D. noxia to 1.204918 d−1 on M. persicae, the mean of generation (T) range was 24.68 d−1 on M. persicae to 22.476 d−1 on A. nerii, similarly, the gross reproductive rate (GRR) range was 172.2 d−1 on D. noxia to 115.02 d−1 on M. persicae and Fecundity (F) eggs per female range was 316.8 on D. noxia to 199.1 on M. persicae. In present Study, age-stage two-sex life table gives complete understanding of predator biological aspects against different aphid species. This study will help us to improve mass rearing and use of M. sexmaculatus in biological control of aphids.
