The mosquito Anopheles (Cellia) oreios sp. n., formerly species 6 of the Australasian Anopheles farauti complex,and a critical review of its biology and relation to disease

Species 6 of the Australasian Anopheles farauti sibling species complex (Diptera: Culicidae) is described and formally named Anopheles oreios Bangs & Harbach, sp. n. Adult, pupal and fourth‐instar larval specimens collected in the Baliem Valley, Papua Province, Indonesia, are characterized and compared with those of Anopheles farauti, Anopheles hinesorum, Anopheles irenicus and Anopheles torresiensis (formerly informally denoted as species 1, 2, 7 and 3, respectively). The variable wings of adult females, the male genitalia, the pupa and the fourth‐instar larva of An. oreios are illustrated and DNA sequence data are included for regions coding for sections of the mitochondrial COI and COII genes. The biology of An. oreios and its relation to malaria transmission are discussed in detail and contrasted with the biology and disease relations of some members of the An. farauti and Anopheles punctulatus sibling species complexes.

Natural History and Comparative Morphology of Immatures of <Emphasis Type="Italic">Gamelia anableps</Emphasis> (C. Felder &amp; R. Felder) (Lepidoptera: Saturniidae,Hemileucinae)

Egg, larva, and pupa of Gamelia anableps (C. Felder & R. Felder, 1874) are described for the first time and the chaetotaxy of the first instar provided. Eggs and selected structures of larvae and pupae were also investigated by means of scanning electron microscopy. Eggs are laid in clusters, are ellipsoidal and laterally flat. Larvae passed through eight instars in about 78 days. Pupation occurs inside a poorly organized cocoon of yellowish silk. The dark brown pupa is cylindrical in shape with appendages firmly fused together and to the body wall. The chaeotaxy is compared with other Saturniidae species belongining to Hemileucinae, Ceratocampinae, and Saturniinae and the natural history of G. anableps compared with other Saturniidae.

Temperature-dependent development and oviposition models of Illeis koebelei (Coleoptera: Coccinellidae)

The yellow ladybeetle, Illeis koebelei Timberlake, is a potential biological agent for powdery mildew. The objective of this study was to construct development and oviposition models of I. koebelei. Development experiment was conducted at eight temperatures ranging from 15.4 to 39.5?°C. Development rates were well fitted with linear and nonlinear models. Lower developmental thresholds for egg, first instar, second instar, third instar, and fourth instar larva, pre-pupa, pupa, and total immature stage were estimated to be 3.6, 12.7, 12.1, 11.3, 11.3, 12.8, 14.7, and 14.2?°C, respectively. Their respective thermal requirements in degree days (DD) were 86.6, 16.0, 22.5, 30.2, 49.3, 14.5, 43.8 and 217.4, respectively. Survivorship was the highest at 25.1?°C for immatures. Oviposition experiment was conducted at nine temperatures, ranging from 15.4 to 35.3?°C. Mean fecundity ranged from 18.6 eggs at 29.3?°C to 205.3 eggs at 20.3?°C. It was well described by extreme value function. Adult survival and cumulative oviposition rates of I. koebelei were fitted to a sigmoid function and a two-parameter Weibull function, respectively. Findings of this study provide basic information for ecology of I. koebelei. They can be used to optimize environmental conditions for mass-rearing and shipping, comparing optimal occurrence conditions between I. koebelei and powdery mildew, and forecasting phenology and population dynamics of I. koebelei in the fields.

Hormonal modulation of glycogen reserves In the fat body of castor semilooperAchaea janata Linn (Lepidoptera,Noctuidea)

Histochemical details of the fat body in the fifth instar larval stage, pupa and adult moth of the castor semilooperAchaea janata were elucidated in detail using light and electron microscopy in conjunction with glycogen storage patterns using polyacrylamide gel electrophoresis. The periodic-acid Schiff staining for glycogen in fat body was maximum in the spinning stage of the larva, when compared to the feeding stage and prepupal stages, and higher in the pupa than in the larva and the adult moth. In insulin injected and juvenile hormone treated fat body, glycogen deposition was more than in glucagon injected tissues. The periodic-acid Schiff stained bands in PAGE had electrophoretic mobility similar to the corresponding protein band numbers, indicating their glycoprotein nature.

INFLUENCE OF EXTREME HIGH TEMPERATURE ON THE BIOLOGY OF VEGETABLE LEAFMINER LIRIOMYZA SATZVAE (DIPTERA: AGROMYZIDAE)

Abstract  Indoor experiments were conducted to test the influence of extreme high temperature (EHT) on the biology of Liriomyza sativae Blanchard. The LD₅₀ of EHT on egg, first instar larva, second instar larva, third instar larva, pupa and adult were 51. 4, 51, 1, 52, 2, 53, 5, 41.1 and 43. 9 C, respectively. The mortality of each stage increased with the prolongation of duration (in hours) of EHT. The quadratic regression equations gave a good estimate of the mortality of the leafminer influenced by durations of EHTs. Under 40 C and a duration of 3 h, there were linear relations between the duration (in days) of EHTs and the pupal mortality, as well as the adult longevity and fecundity.
