Feeding Potential

Biology and feeding potential of Coccinella septempunctata (Linn.) were studied in laboratory on 3rd instar nymphs of mustard aphid (Lipaphis erysimi Kalt.) at two different temperature regimes. At 30± 20C, fecundity, oviposition period, hatchability of eggs, male and female longevity (232±70.46, 12.8±3.91, 82.87±6.66, 22.70 ± 2.21and 26.60 ± 4.45, respectively) were higher and incubation period, pre-oviposition period, total grub duration and pupal duration (2.6±0.51, 6.5±3.53, 8.7 ± 1.63 and 5.1 ± 1.10, respectively) were lesser in comparison to 25± 20C where fecundity, oviposition period, hatchability of eggs, male and female longevity, incubation period, preoviposition period, total grub duration and pupal duration were 169.8±61.12, 7.9±1.37, 71.68±4.08, 16.2 ± 1.31 and 21.50 ± 1.95, 2.9±0.73, 7.7±2.49, 11.1 ± 1.52 and 5.8 ± 0.918, respectively . At 27± 2 0C, total mustard aphid consumption by a grub of C. septempunctata during the whole life span, was 424.4±2.78 mustard aphids in comparison to 272.64±1.79 mustard aphid at 23± 20C. Similarly an adult male and female consumed 103.2±1.52 and 116.6 ±1.46 aphids per day respectively at 27± 2 0C in comparison to 65.6 ± 1.02 and 71.8 ± 1.60 at 23± 20C. Thus, at both temperatures aphid consumption increased gradually till 4th instar and 30±20C was found to be most suitable temperature as compared to 25±20C for the life history of C. septempunctata. Hence, it could be concluded that C. septempunctata might play a suitable role in biointensive Integrated Pest Management programme because of better longevity and high predatory potential against the mustard aphid.

Predatory Potential

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.

A study was undertaken to assess the effectiveness of five insecticides against the Delhi and Bikaner populations of mustard aphid, Lipaphis erysimi (Kalt.), using the leaf dip method, and against Coccinella septempunctata L. in semi-field conditions. Acetamiprid and thiamethoxam were found to be more toxic than other insecticides. After 24 h, the LC50 values for the Bikaner population against different insecticides were 7.0, 6.0, 4.0, 3.0 and 2.0 ppm for carbosulfan, bifenthrin, imidacloprid, acetamiprid and thiamethoxam, respectively. Similarly, the descending order of toxicity for the Delhi population was acetamiprid (7.0 ppm), thiamethoxam (9.0 ppm), imidacloprid (15.0 ppm), carbosulfan (32.0 ppm) and bifenthrin (36.0 ppm). The relative toxicity values suggest that in both populations, thiamethoxam and acetamiprid show the highest toxicity. Carbosulfan and bifenthrin were highly toxic to coccinellid grubs and resulted in 100% mortality in semi-field conditions, whereas the neonicotinoids acetamiprid and thiamethoxam showed less mortality. It showed the tolerance of coccinellidae against neonicotinoids under semi-field conditions.

Experiments on the preying capability of different stages of larvae of coccinellid and syrphid flies on the mustard aphid, Lipaphis erysimi (Kalt.), were conducted in a laboratory during the winter cropping seasons of 2009&ndash;2010 and 2010&ndash;2011. Results revealed that grubs of the Coccinella septempunctata Linn. preyed the highest number of mustard aphids (average 61.42 aphids/day) followed by Syrphus confrater Wied (34.81 aphids/day), Syrphus balteatus Deg. (32.26 aphids/day) and Ischiodon scutellaris Fab. (27.76 aphids/day) during their larval span. Among the larval stages of the coccinellid and syrphid predators, it was also analysed that the last juvenile stage of the predators was proved the mightiest devourer against the aphid L. erysimi. These predators could be used effectively for the management of L. erysimi on rapeseed-mustard crop.

The experiment was conducted in the laboratory of the Department of Entomology, Shere- Bangla Agricultural University, Dhaka during the period from May 2009 to April 2010 to study the biology of the Angoumois grain moth, Sitotroga cerealella (Oliver) in Bangladesh. The ovipositional period, incubation period, larval period, pre-pupal period and pupal period of Angoumois grain moth were 3.67 days, 5.5 days, 25.2 days, 3.0 days and 5.0 days, respectively; male and female longevity of moth were 8.0 and10 days, respectively. The lengths of all five larval instars were 1.0 ± 0.00, 2.0 ± 0.02, 4.0 ± 0.06, 5.0 ± 0.03 and 4.0 ± 0.06 mm, and the widths were 0.10 ± 0.0, 0.4 ± 0.0, 0.6 ± 0.01, 0.8 ± 0.02 and 1.0 ± 0.09 mm, respectively. The length and width of the pre-pupa and the pupa were 4.0 ± 0.02, 3.5 ± 0.01 mm and 1.20 ± 0.05, 1.50 ± 0.03 mm respectively. The length of male and female was 11.2 ± 0.09 and 12.07 ± 0.06 mm respectively. J. Asiat. Soc. Bangladesh, Sci. 39(1): 61-67, June 2013 DOI: http://dx.doi.org/10.3329/jasbs.v39i1.16034

Studies were conducted in the field to determine the effectiveness of three insectidicdes, Metasystox-R 25EC, Dimethion 40 EC, and Fentro 50 EC applied against mustard aphid, Lipaphis erysimi Kalt. and measure their toxic action on the predator Coccinella septempunctata L. The mustard plants were sprayed with the insecticides at 0.05% and 0.025% a. i. at 50 and 70 days after sowing. The mortality of both mustard aphid and the predator was assessed at 1, 4, and 7 days after first and second spraying of insecticides. Metasystox-R showed the most effectiveness among the three insecticides causing the highest mortality of mustard aphid followed by Dimethion and Fentro. But the lowest mortality of Coccinella septempunctata was obtained in Dimethion treated plot, and Fentro treated plot showed the highest mortality indicating that the Dimethion was less toxic and Fentro was more toxic to the predator.
