“…In all four papers the laboratory experiments were complemented by observation of predator -prey relations in the fi eld. In India, Omkar and his colleagues made comparative studies for four species: C. septempunctata (Omkar & Srivastava 2003 ), C. leonina transversalis (Omkar & James 2004 ), Menochilus sexmaculatus (Omkar & Bind 2004 ), and P. dissecta . They compared the performance of ladybirds when reared on seven aphid species as prey.…”

“…Rather surprising, therefore, are the reports that larvae of three coccinellid species completed their development with quite a high survival on A. nerii , reared in this experiment, however, on Calotropis procera . Survival was as follows: C. septempunctata , 43.9% (Omkar & Srivastava 2003 ); C. leonina transversalis , 37.8% (Omkar & James 2004 ); Menochilus sexmaculatus , 32.3% (Omkar & Bind 2004 ).…”

“…Due to the importance of predatory ladybird beetles in aphid biological control, it is necessary to investigate the factors that influence the resource quality of aphids as their prey. Recently, some information has become available on the relative suitability of aphid species for some important ladybird beetles, including Coccinella septempunctata L. (Hauge et al 1998;Takizawa et al 2000;Omkar and Srivastava 2003;Kalushkov and Hodek 2004;Evans et al 2004), Harmonia axyridis Pallas (Takizawa et al 2000;Tsaganou et al 2004;Soares et al 2005;Matos and Obrycki 2006), Propylea dissecta (Mulsant) (Pervez and Omkar 2004;Omkar and Mishra 2005), Coccinella transversalis Faldermann (Omkar and James 2004), Cheilomenes sexmaculata (Fabricius) (Omkar and Bind 2004) and Cycloneda sanguinea (L.) (Isiber and Copland 2002). The above investigations show that the suitability of aphids as prey varies with species of aphids and predators.…”

The aphidophagous ladybird beetle, Hippodamia variegata (Goeze), is an important predator in many agricultural ecosystems. However, information on the influence of the prey's host plant species on its life history characteristics is still absent in the literature. Therefore, five host plant species of Aphis gossypii Glover, viz. Cucumis sativus L., Cucurbita pepo var. medullosa L., Cucurbita moschata var. melonaeformis Poiret, Cucumis melo var. cantalupensis L. and Lagenaria siceraria var. gourda Standl., were selected to study the influence of the prey's host plant species on the development, survival, reproduction and life table parameters of H. variegata in the laboratory at 25°C. The results showed that all of A. gossypii from five host plant species used were acceptable for the growth, development and reproduction of H. variegata. However, the suitability of aphids from various host plants was different for this ladybird beetle. The complete preimaginal development was longest (14.51 ± 0.17 days) when reared with aphids on C. melo var. cantalupensis and shortest (12.60 ± 0.11 days) on L. siceraria var. gourda. Total immature survival from egg to adult was highest (58.97%) on L. siceraria var. gourda and lowest (44.06%) on C. melo var. cantalupensis. Based on the intrinsic rate of increase as an index of suitability of prey host plant species on the population increase of H. variegata, the suitability in decreasing order was: L. siceraria var. gourda [ C. moschata var. melonaeformis [ C. pepo var. medullosa [ C. melo var. cantalupensis [ C. sativus. This study offered opportunities for better understanding the tritrophic interactions of the plant-aphid-predator relationship.

“…The adults were sexed according to their size (males being smaller than females) (Omkar & Bind 2004;Dixon 2000) and opposite sexes were paired in transparent plastic Petri dishes (9.0 Â 2.0 cm). The pairs thus formed were allowed to mate and observed for oviposition.…”

The rhythmicity in insects has been widely studied by researchers showing changes in the physiology, behavior, and population synchrony of the insects. One of the most important rhythms which control the population is oviposition rhythm. Oviposition/egg-laying rhythm in an aphidophagous ladybird, Cheilomenes sexmaculata (Fabricius), was found to have two components, viz. complete ovipositional cycle and diel cycle. The complete ovipositional cycle was perceived at three levels, viz. a polynomial curve, two lunar rhythms (ca. 28 days), and daily oscillations. Lunar rhythms are deciphered for the first time in the ovipositional cycle of a ladybird. In a diel cycle, most of the oviposition (71%) occurred during scotophase, with a peak (48%) during early scotophase (i.e. 1200-1500 h). Occurrence of most of the oviposition during a phase when predatory activities are low (i.e. scotophase) appears to be a survival strategy. A mathematical model was developed to predict the ovipositional cycle. Fourier analysis has been applied to the data to find out the periods of different cycles of oviposition rhythm with the help of Matlab software. The average oviposition duration was 63.3 ± 0.4 days, with average lifetime fecundity of 975 ± 247 eggs. Two lunar rhythms with a periodicity of approximately 28 days were found within a complete ovipositional cycle. Periodogram obtained from Fourier analysis suggests that a diel cycle of 3.83 slots, i.e. after every 3.83 slots of the day the number of eggs reduces to minimum.
