The Dynamics of an Adult Population of Aedes aegypti in Relation to Dengue Haemorrhagic Fever in Bangkok

Two aedine and three anopheline species were allowed to blood-feed to repletion, and their host-seeking behavior was measured with an olfactometer at intervals afterward. Both Aedes aegypti (L.) and Ae. albopictus (Skuse) were inhibited from subsequently seeking a host during the gonotrophic cycle, but Anopheles gambiae Giles, An. albimanus Wiedemann, and An. freeborni Aitken, all showed varying degrees of hostseeking behavior while their eggs matured. Continued host-seeking by some anophelines during the gonotrophic cycle has important implications for some assumptions commonly made about mosquito behavior and parasite transmission.

“…In some studies, released mosquitoes tended to cluster around houses with some dispersal towards adjacent houses, and mosquitoes released on the perimeter of villages moved towards the centre of the village (Sheppard et al, 1969;Trpis and Hausemann, 1986;Getis et al, 2003;Harrington et al, 2005;Maciel-de-Freitas et al, 2006).

“…Ecological features including accessible water, vegetation patterns, humidity, contribute to determining the mosquito distribution. The range of dispersal is dependent upon a mosquito's ability to remain in flight and the availability and abundance of shelter, food sources, hosts for blood meals and suitable oviposition sites (Sheppard et al, 1969). Suitable host availability may reduce dispersal as reported by Suwonkerd et al (2006) where fewer Ae.…”

“…This species has been reported to usually fly from 50 m to 300 m during its lifetime, with mean dispersal distances of 28 m to 199 m (Harrington et al, 2005). Experiments in different parts of the world involving the release and recapture of adults suggest that most are recovered within 20 m to 50 m of the release point, with a small percentage reaching distances greater than 170 m and not more than 200 m (Morlan and Hayes, 1958;Sheppard et al, 1969;McDonald, 1977;Trpis and Häusermann, 1986;Muir and Kay, 1998;Ordoñez-Gonzalez et al, 2001;Harrington et al, 2005;Russell et al, 2005;Lourenço-de-Oliveira, 2007a, 2007b;Valerio et al, 2012).…”

FOREWORD │ 3SAFETY ASSESSMENTOF TRANSGENIC ORGANISMSIN THE ENVIRONMENT, VOLUME 8 © OECD 2018 ForewordModern biotechnologies are applied to plants species (crops, flowers, trees), animals and micro-organisms. The safety of the resulting transgenic organisms when released in the environment for their use in agriculture, forestry, the food and feed industry or for other applications represents a challenging issue. Genetically engineered products are rigorously assessed by their developers during their elaboration, and by governments when ready for release, to ensure high safety standards. This remains essential with new biotechnology developments using insects to fight against disease outbreaks: engineered mosquitoes need to be evaluated through a scientifically sound approach to risk/safety assessment that will inform biosafety regulators and support the decision concerning the release of these novel organisms in the environment.The OECD offers a long-standing recognised expertise in biosafety and contributes to facilitating an harmonised approach. The OECD's Working Group on Harmonisation of Regulatory Oversight in Biotechnology (WG-HROB) was established in 1995. The WG-HROB gathers national authorities responsible for the environmental risk/safety assessment of products of modern biotechnology in OECD countries and other economies. International organisations and experts involved in biosafety activities are a...

An Approximate Confidence Interval for Survival Probability Based on Jackson's Method for the Analysis of Mark-recapture Data

A common problem in mark‐recapture studies is that the effects of mortality and emigration are confounded. Jackson's method is a simple and elegant way to separate these effects. This paper describes an approximate confidence interval for survival probability based on Jackson's method. Some simulation results are presented suggesting that the confidence interval works well in situations where the bias of Jackson's method is small.
