Campus Kumaun University, Nainital, Uttarakhand, India 2Department of Zoology and Environmental Sciences, Gurukula Kangri University, Haridwar, India Abstract Studies on prey consumption of larvae and adults of Adalia tetraspilota (Hope) (Coleoptera: Coccinellidae) was conducted in the laboratory on green peach aphid, Myzus persicae (Sulzer) (Homoptera: Aphididae). In larval form 4th instar was the most efficient consumer with an average of 39.96 ± 1.04 aphids larva-1day-1 followed by 3rd instar with an average of 20.90 ± 0.58 larva-1day-1. Feeding potentials of adult coccinellids increased with increase in age. In female the highest consumption of aphids was recorded on the 23rd day of its emergence while in case of male it was recorded on 24th day. Female adult consumed more aphids (39.83 ± 11.39 aphids day-1) than male (31.70 ± 8.07 aphids day-1).

Temperature-Dependent Development of the Two-Spotted Ladybeetle
Journal of Insect Science: Vol. 10 | Article 124 Jalali et al. Temperature-dependent development of the two-spotted ladybeetle, Adalia bipunctata, on the green peach aphid, Myzus persicae, and a factitious food under constant temperatures Mohammad. Amin. Jalali1,2, Luc Tirry1, Abbas Arbab3 and Patrick De Clercq1a 1Department of Crop Protection, Ghent University, Coupure Links 653, B-9000 Ghent, Belgium 2Current Address: Department of Crop Protection, Vali-e Asr University, P.O.Box 771393641, Rafsanjan, Iran 3Department of Plant Protection, Islamic Azad University, Takestan Branch P.O. Box: 34819-49479 Takestan- IRAN Abstract The ability of a natural enemy to tolerate a wide temperature range is a critical factor in the evaluation of its suitability as a biological control agent. In the current study, temperature- dependent development of the two-spotted ladybeetle A. bipunctata L. (Coleoptera: Coccinellidae) was evaluated on Myzus persicae (Sulzer) (Hemiptera: Aphididae) and a factitious food consisting of moist bee pollen and Ephestia kuehniella Zeller (Lepidoptera: Pyralidae) eggs under six constant temperatures ranging from 15 to 35° C. On both diets, the developmental rate of A. bipunctata showed a positive linear relationship with temperature in the range of 15-30° C, but the ladybird failed to develop to the adult stage at 35° C. Total immature mortality in the temperature range of 15-30° C ranged from 24.30-69.40% and 40.47-76.15% on the aphid prey and factitious food, respectively. One linear and two non- linear models were fitted to the data. The linear model successfully predicted the lower developmental thresholds and thermal constants of the predator. -

Polymorphism in the 2-Spot Ladybird, Adalla Bipunctata (Coleoptera, Coccinellidae)
Heredity 70(1993)172—178 Received 5 June 1992 Genetical Society of Great Britain Sperm competition and melanic polymorphism in the 2-spot ladybird, Adalla bipunctata (Coleoptera, Coccinellidae) PETER W. DE JONG*, MICHELLE D. VERHOOG & PAUL M. BRAKEFIELD Section of Evolutionary Biology, Department of Population Biology, University of Leiden, Schelpenkade 14a, 2313 ZT Leiden, The Netherlands Spermprecedence was investigated in the 2-spot ladybird, Ada/ia bipunctata by utilizing a di-allelic colour marker gene. Non-melanic (homozygous recessive) virgin females were mated once with a non-melanic male and after subsequent laying of fertile eggs they were mated with a melanic male of known genotype. Frequencies of colour morphs in the offspring provided evidence for almost complete second male sperm precedence, although the data from certain matings do not completely exclude the possibility of first male sperm precedence. The results are discussed in the light of the hypothesis of thermal melanism. Keywords:Ada/iabipunctata, female rejection, sexual selection, sperm competition, thermal melanism.

Les Tachinidae De La Manche
Les Tachinidae de la Manche : début de l’enquête et première liste (Diptera Brachycera) La famille de mouches que nous allons aborder dans cet article offre le paradoxe d’être à la fois l’une des plus riches en espèces et l’une des plus mal connues des entomologistes. Discrètes, souvent de petite taille et peu colorées, elles passent facilement inaperçues. Totalement ignorées du profane, elles n’ont reçu aucun nom vernaculaire et c’est à peine si les guides de vulgarisation représentent quelques espèces, 6 par exemple dans CHINERY (1986) contre 22 syrphes, famille d’ampleur comparable, soit moins de 1% de la faune européenne ! Un guide spécialisé dans les diptères, J. & H. HAUPT (1998), dont l’éditeur suisse annonce sans vergogne en couverture « l’identification des espèces européennes », illustre 13 espèces, soit 1,5% de la faune d’Europe. Il est certain que l’ampleur de la tâche a pu rebuter les diptéristes de notre pays, d’autant plus qu’aujourd’hui encore aucun ouvrage complet de détermination n’est actuellement disponible en langue française. Et pourtant ces mouches ne manquent pas d’attrait ! De nombreuses espèces sont d’une taille respectable, sous la loupe beaucoup même offrent un aspect séduisant par leurs couleurs veloutées, leurs reflets pruineux, leur système organisé de poils et de soies, toutes surtout ont une biologie complexe, captivante et encore mal étudiée. Pour tout dire, cette enquête limitée à la Manche (voir L’Argiope No 67) s’annonce passionnante car la page est totalement vierge et le champ de recherche immense. Bien sûr, les obstacles sont tels que l’inventaire devra être abordé avec prudence. -
Quoted, May Be Found in Marriner (1926, 1939A and B), Bayford (1947), Allen (Sg) and Conway (1958)
GEOGRAPHIC VARIATION IN THE TWO-SPOT LADYBiRD IN ENGLAND AND WALES E. R. CREED Genetics Laboratory, DepartmentofZoology, Oxford Received6.v.65 1.INTRODUCTION Twoof the most variable species of ladybird in this country are Adalia bipunctata and A. decempunctata. Hawkes (5920, 5927) drew attention to the differences in frequency of the varieties of A. bipunctata in this country, mainly around Birmingham; she found that the black forms predominated in the city while they were less common or rare else- where. In London the black forms comprised only a few per cent, of the population. Further information, though figures are not always quoted, may be found in Marriner (1926, 1939a and b), Bayford (1947), Allen (sg) and Conway (1958). Theinsect has also attracted attention in Europe, but more so in some countries than others. It was in this species that Timofeeff- Ressovsky (i 94oa, i 94ob) demonstrated the action of strong selection in Berlin. He found that the black varieties had a higher mortality than the red during hibernation, but that their relative numbers increased again during the summer. Lusis (ig6i) has reviewed the distribution of the varieties of A. bipunctata in Europe and western Russia and suggests that two conditions tend to favour the black ones: (x) in places with a maritime, more humid climate the percentage of black forms in the populations of Adalia bipunctata L. is as a rule higher than in places with a more continental climate, and (2) in large cities, especially in those with highly developed industry, the percentage of black forms irs the adalia-populations is higher than in towns and in the countryside with similar climate." Unfortunately the only figures for the British Isles apparently available to Lusis were those in Hawkes' second paper (5927), and some of these he disregards. -
Functional Response of Adalia Tetraspilota (Hope) (Coleoptera: Coccinellidae) on Cabbage Aphid, Brevicoryne Brassicae (L.) (Hemiptera: Aphididae)
J. Biol. Control, 23(3): 243–248, 2009 Functional response of Adalia tetraspilota (Hope) (Coleoptera: Coccinellidae) on cabbage aphid, Brevicoryne brassicae (L.) (Hemiptera: Aphididae) A. A. KHAN Division of Entomology, Sher–e–Kashmir University of Agricultural Sciences and Technology (K), Shalimar Campus, Srinagar 191121, Jammu and Kashmir, India. E-mail: [email protected] ABSTRACT: A study was conducted to assess the functional response of different life stages of the predacious coccinellid, Adalia tetraspilota (Hope) feeding on various densities of cabbage aphid, Brevicoryne brassicae (L.) under controlled conditions. It revealed that all stages of A. tetraspilota exhibit Type II functional response curve (a curvilinear rise to plateau) as B. brassicae densities increase and the curve predicted by Holling’s disk equation did not differ significantly from the observed functional response curve. The fourth instar larva consumed more aphids (28.40 aphids / day) followed by adult female (25.06 aphids / day), third instar larva (24.06 aphids / day), second instar larva (21.73 aphids / day), adult male (20.06 aphids / day) and first instar (13.06 aphids / day). The maximum search rate with shortest handling time was recorded for fourth instar larva (0.6383) followed by adult female (0.6264). The results suggest that the fourth instar larva are best suited for field releases for the management ofB. brassicae. However, further field experiments are needed for confirming its potential. KEY WORDS: Adalia tetraspilota, Aphididae, Brevicoryne brassicae, Coccinellidae, functional response, handling time, predation, search rates INTRODUCTION (Type I), decreasing (Type II), increasing (Type III). This could further be simplified in terms of density dependence The cabbage aphid, Brevicoryne brassicae (L.) as constant (I), decreasing (II) and increasing (III) rates (Hemiptera: Aphididae) is an important worldwide pest of prey consumption and yield density dependent prey of cruciferous vegetables in temperate region. -
