Changes in nuclear phenotype frequencies following sequential cold shocks in Triatoma infestans (Hemiptera, Reduviidae).
The nuclear phenotypes of Malpighian tubule cells in fifth instar nymphs of Triatoma infestans, one of the most important vectors of Chagas disease, were studied following sequential shocks at 0 degrees C, separated by intervals of 8 h and 24 h at 30 degrees C, under conditions of moderate fasting and full nourishment. The insects pertained to colonies reared in the laboratory and originated fr...
متن کاملBehavioural response of Triatoma infestans (Klug) (Hemiptera: Reduviidae) to quinazolines.
The behavioural responses of the haematophagous bug Triatoma infestans towards some previously identified components of its faeces: 4-methylquinazoline, 2,4- dimethylquinazoline and their mixtures were evaluated using a video tracking system. Fifth instar nymphs and females but not males were significantly attracted to polyethylene glycol formulations of 4-methyl + 2,4-dimethylquinazoline (50 m...
متن کاملToxicity of non-pyrethroid insecticides against Triatoma infestans (Hemiptera: Reduviidae).
Triatoma infestans (Klug) is the main vector of Chagas disease, which is a public health concern in most Latin American countries. The prevention of Chagas disease is based on the chemical control of the vector using pyrethroid insecticides. In the last decade, different levels of deltamethrin resistance have been detected in certain areas of Argentina and Bolivia. Because of this, alternative ...
متن کاملEffect of sequential cold shocks on survival and molting rate in Triatoma infestans klug.
The survival and molting incidence in Triatoma infestans, a vector of Chagas disease, were investigated following sequential shocks at 0 degrees C in fifth instar nymphs under moderate fasting and full nutritional conditions. The shocks were separated by intervals of 8 h and 24 h at 30 degrees C. The results indicated that in terms of insect survival, T. infestans is tolerant to a single cold s...
متن کاملActivity pattern in relation to refuge exploitation and feeding in Triatoma infestans (Hemiptera: Reduviidae).
The pattern of locomotion activity was studied in Triatoma infestans, in relation to the use of an artificial refuge offered to the bugs in an experimental arena. In assays performed with insects that had a post-ecdysis starvation period of 1 week, the activity was low and mainly related to refuge leaving or entering. Insects that had gone through a longer period of starvation (6 weeks) exhibit...
