Life history of the mealybug, Maconellicoccus hirsutus (Hemiptera: Pseudococcidae), at constant temperatures.
Important life history parameters of the mealybug, Maconellicoccus hirsutus (Green), were characterized on hibiscus (Hibiscus rosa-sinensis L.) cuttings at six constant temperatures between 15 and 35 degrees C. The development of M. hirsutus was the fastest at 27 degrees C, where the mealybugs completed development in approximately 29 d. The lower (T(min)) and upper (T(max)) developmental thres...
متن کاملEffect on biology of jute indigo caterpillar, Spodoptera litura (Fabricius) under five different constant temperatures
Effect of six constant temperatures viz., 18±1 °C, 21±1 °C, 24±1 °C, 27±1 °C, 30±1 °C and 33±1 °C on growth, development and survival of Spodoptera litura (Fabricius). Development rate of egg, larvae, pupae and adult gradually increased with increase in temperature, while the total development period decreased. The total life span of the insect decreased from 64.19±2.86 days at 18±1 °C to 27.18...
متن کاملBioclimatic Thresholds, Thermal Constants and Survival of Mealybug, Phenacoccus solenopsis (Hemiptera: Pseudococcidae) in Response to Constant Temperatures on Hibiscus
Temperature-driven development and survival rates of the mealybug, Phenacoccussolenopsis Tinsley (Hemiptera: Pseudococcidae) were examined at nine constant temperatures (15, 20, 25, 27, 30, 32, 35 and 40°C) on hibiscus (Hibiscusrosa -sinensis L.). Crawlers successfully completed development to adult stage between 15 and 35°C, although their survival was affected at low temperatures. Two linear ...
متن کاملThe challenge of reproductive and developmental toxicology under REACH.
The European Union's REACH regulation has explicit requirements for reproductive and developmental toxicity data on all substances manufactured in or imported into the European Union at > or = 10 metric tons/year. Meeting the data requirements with whole-animal testing could result in the use of almost 22 million vertebrate animals for the registration of existing chemicals and cost up to sever...
متن کامل6 Reproductive and Developmental
: Apical tests for reproductive or developmental toxicity assess the potential for a compound to affect any of the thousands of steps involved in making gametes and in the successful development of a fully functional offspring. Conventionally, this is thought to require at least 21 days for rodent female reproduction and for development, and close to 70 days for spermatogenesis. Short-term test...
