1. Behaviour of young rhinoceros beetles, oryctes rhinoceros

Author:

Subject:
Oryctes rhinoceros; eggs; females; insect flight; males; molting; pupation; young adults
Abstract:
... The behaviour of young adults of Oryctes rhinoceros was studied. In the field the young beetles remained at the site of pupation for 3--4 weeks after the adult moult. In the laboratory 3-week-old females and 5-week-oId males were able to mate before the first feeding and before the first flight. However, in the field mating apparently took place after the young beetles had left the site of pupatio ...

Abstract:
... Radioactive phosphorus was fed to laboratory-reared male pink bollworms, Pectinophora gossypiella (Saunders), for studies of dispersal and mating in the field. Released moths either irradiated with 20 Krad or unirradiated, were found predominantly within a few hundred meters of the release points. Prior to formation of a plant canopy, daytime-resting places of moths were soil crevices at the bases ...

3. Flight activity of the thistle lace bug, tingis ampliata (heteroptera)

Entomologia experimentalis et applicata 1975 v. no. pp. 123-134

Subject:
Tingis ampliata; adults; autumn; females; flight; flight muscles; hibernation; immatures; males; seasonal variation; spring; summer; thorax; walking; wings; winter
Abstract:
... Tingis ampliata has very limited capacity for flight; a few sexually immature individuals of both sexes flew during post-hibernation emergence in spring from early May to June. Flight did not occur in autumn, but bugs warmed to about 35°C apparently attempted flight by opening their wings. When too warm or when not warm enough bugs resorted to active walking rather than attempting to fly. After hi ...

DDT (pesticide); Musca domestica; chromosomes; fenitrothion; genetic analysis; homozygosity; lyases; methoxychlor; modifiers (genes); Czechoslovakia
Abstract:
... Genetic analysis of the factors causing resistance was carried out in strain H captured in Czechoslovakia in 1961 and in the more resistant strain HS obtained as a result of laboratory selection of strain H. In both strains DDT and methoxychlor resistance is the result of interaction of factors localized on chromosome I, II, and III. In the homozygous state, the highest degree of DDT and methoxych ...

Abstract:
... Female and male houseflies were dosed topically with DDT and malathion at fixed doses. By separating flies, before dosage, into weight-classes according to their individual body weight, it was shown that susceptibility decreased markedly with increasing body weight. Probit mortality was linearly related to the logarithm of the body weight. ...

Abstract:
... Several methyl-branched saturated C₃₂, C₃₃, and C₃₄ hydrocarbons have been identified from larvae and mandibular glands of Heliothis virescens (F.) (Lepidoptera, Noctuidae) that trigger a short-range host-seeking response of its parasitoid, Cardiochiles nigriceps, Viereck (Hymenoptera: Braconidae). Although the individual components elicited a response, a mixture of the most active C₃₂, C₃₃, and C ...

Abstract:
... The dose required to induce supernumerary molting was used to estimate the sensitivity to a juvenile hormone analogue mixture in five different forms of M. euphorbiae. Apterous forms (sexuparae and oviparae) showed the highest sensitivity with an ED₅₀ of approximately 0.4 μg/mg wet weight. Males were about seven times as tolerant as apterae with an ED₅₀ of 2.38 μg/mg wet weight. Alate female forms ...

Abstract:
... The temperature reactions of the larvae of Dermestes maculatus Degeer were studied using a radial temperature gradient apparatus. The larvae consistently avoided the hottest zones of the gradients (39.5° or 44.0°C) and were preferentially distributed in the cooler zones 23.5°-25.0°, or 32°-34°. This pattern of behaviour has been discussed in relation to the observed temperature reactions of the be ...

In the present investigation, females laid more eggs on brussels sprouts than on artificial leaves. The majority of eggs was laid on the underside even if it was the morphological upper surface. Brussels sprouts was preferred against turnip cabbage, sugar beet and be ...

Abstract:
... Compared with adults from a wild strain, phenotypically normal-eyed heterozygotes from a stock culture of the red-eyed (r/r) recessive mutation strain were confirmed to produce brachypterous progeny relatively more abundantly. The wing character has been shown not to be linked with the r gene, but the association that has developed between them may perhaps be the result of culture methods which ha ...

Abstract:
... Field observation indicated that A. bibens is an important predator of several Tetranychus-species in parts of Madagascar. Its dependence on water for drinking was demonstrated; this feature limits its presence to more humid biotopes. Its importance in the irrigated areas of the dry southwest is stressed. A. bibens proved capable of eradicating T. urticae on potted bean plants. Predation and ovipo ...

Abstract:
... Presence of queens decreases the incidence of diapause in last-instar larvae and thereby increases the production of workers as opposed to sexual females. Neither removal of the mandibular nor pharyngeal glands from nursing workers nor application of the contents to larvae increases the proportion that pupate, but prey and especially water supply both do. Queens, even dead ones, increase the amoun ...
