“…Additionally, those females that did enter the sprayed hut became stimulated (irritated) and escaped the hut much quicker than those mosqutioes present in the unsprayed hut. Another study comparing biting patterns of Anopheles minimus in Thailand showed a 71.5% decline in attempted blood feeding inside the DDT treated hut and a 42.8% reduction in blood feeding success in a deltamethrin treated hut (Polsomboon et al, 2008). Using the same huts, observing human landing patterns of Anopheles dirus complex found that the relative risk (odds) of female mosquitoes entering and attempting to feed were half the number when exposed to DDT compared with the deltamethrin treated hut (Malaithong et al, 2010).…”

“…This modular system is substantially reduced in size compared to the previous excito-repellency box and minimizes the treated surface area and therefore the amount of chemical required for testing. In field observations, numerous attempts have been made to determine behavioal responses of mosquitoes using specially constructed experimental huts (Smith, 1965;Roberts et al, 1984Roberts et al, , 1987Roberts & Alecrim, 1991;Rozendaal et al, 1989;Bangs, 1999;Grieco et al, 2000;Grieco et al, 2007;Polsomboon et al, 2008;Malaithong et al, 2010). Most experimental hut studies have been conducted to observe the behavior of Anopheles mosquitoes with far fewer studies on other genera.…”

“…In 2006, a more field compatible device was designed with a substantial reduction in chamber size to minimize the amount of chemical and treated paper required, provide greater ease of test preparation and allow use of a small number of test specimens (15 vs. 25 females) compared to the larger version (Tanasinchayakul et al, 2006). Using this system, consistent and reliable results have been produced (Muenworn et al, 2006;Polsomboon et al, 2008;Thanispong et al, 2009;Mongkalagoon et al, 2009). The system comprises of 4 outer stainless steel sheet metal walls (Fig.…”

“…Response outcomes by malaria vectors to DDT and deltamethrin have previously been reported in Thailand (Ismail et al 1974(Ismail et al , 1975Chareonviriyaphap et al 2001Chareonviriyaphap et al , 2004Sungvornyothin et al 2001;Pothikasikorn et al 2005;Polsomboon et al 2008). Most work on the excitation and repellency of mosquitoes to insecticides has been conducted under laboratory-controlled conditions using an excito-repellency test system (Chareonviriyaphap et al , 2004Sungvornyothin et al 2001;Pothikasikorn et al 2005), whereas fewer investigations have used Þeld trials to evaluate the responses of Anopheles mosquitoes to insecticides using experimental huts (Ismail et al 1975, Prasittisuk et al 1996, Suwonkerd et al 1997, Polsomboon et al 2008. It remains difÞcult to extrapolate bioassay data on insecticidal effects (whether toxicity or excitation) and degree of protection against mosquito blood feeding inside a house or community-wide setting.…”

Anopheles dirus females landing on humans inside experimental huts treated with residual applications of DDT or deltamethrin were observed during the wet season in Pu Teuy Village, Kanchanaburi Province, western Thailand. Two identical experimental huts were constructed in the fashion of typical local rural Thai homes. Pretreatment (baseline) human-landing collections (HLC) in both huts showed an early evening peak of activity between 1900 and 2000 h with no significant difference in numbers of mosquitoes captured between huts over a period of 30 collection nights. During posttreatment HLC, female mosquitoes continued to show greater landing activity inside huts fitted with insecticide-treated panels during the first half of the evening compared with the second half. A greater number (proportion) of An. dirus females landed on humans in the hut treated with deltamethrin compared with DDT. Comparing pre- and posttreatment HLC, the DDT-treated hut showed a 79.4% decline in attempted blood feeding, whereas exposure to deltamethrin resulted in a 56.3% human-landing reduction. An odds ratio was performed to demonstrate the relative probability (risk) of mosquitoes entering and attempting to blood feed in the two treated huts compared with untreated control huts. Mosquitoes were approximately 0.47 times less likely to land on humans inside a DDT-treated hut compared with the deltamethrin-treated hut. Although both chemicals exerted strong excitatory responses, DDT appears to have a more pronounced and significant (P = 0.002) effect on behavior than deltamethrin, resulting in greater movement away from the insecticide source and thus potential reduction of blood-feeding activity.

“…To better approximate insect behaviour in natural field settings, numerous experiments have been made over many decades using specially constructed experimental huts (Smith, 1965;Rozendaal et al, 1989;Roberts and Alecrim, 1991;Bangs, 1999;Grieco et al, 2000Grieco et al, , 2007Polsomboon et al, 2008;Malaithong et al, 2010). Most experimental hut studies have been conducted to observe the behaviour of Anopheles mosquitoes; however, Grieco et al (2007) successfully demonstrated that chemical actions could be observed in experimental huts using Ae.…”

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...
