Taschenbuch. Condición: Neu. Neuware - During the last few decades, cole crops production are severely affected by diamondback moth (DBM), Plutella xylostella infestation as this insect developed multiple resistance to commonly used insecticides resulting in population outbreak, causing devastation and complete crop loss throughout the world. The use of manipulating integrated methodologies are reducing the host plant resistant and natural enemies and also increasing the production cost. The failure of all management strategies forced to study thermo regulatory, tritrophic relationship of development of DBM with host plant and environmental condition. The present monographs deals with the population dynamics and life table studies of DBM, estimation of thermal threshold level, and calculation of degree days at different temperature and host plants in laboratory and field conditions.…

Condición: Hervorragend. Zustand: Hervorragend | Sprache: Italienisch | Produktart: Bücher | L'uso di diversi metodi di campionamento è utile per l'indagine sulla fauna di insetti della cipolla e per fornire una comprensione dei tripidi della cipolla, Thrips tabaci in relazione alle cultivar e ai fattori biotici e abiotici. Trentasei insetti e ragni appartenenti a 17 famiglie e 10 ordini sono associati alle cultivar di cipolla. L'individuazione precoce e il monitoraggio di T. tabaci possono essere effettuati utilizzando trappole appiccicose o campionamenti di piante. I fattori abiotici (temperatura e umidità relativa) sono i principali fattori che regolano la crescita della popolazione. I nemici naturali e altri insetti parassiti della cipolla sono correlati in modo non significativo con T. tabaci in condizioni di campo. La trappola blu e il campionamento delle piante sono i metodi migliori per determinare il livello di infestazione. Il livello di soglia economica potrebbe essere determinato dalle trappole adesive, ma necessita di ulteriori indagini. Le trappole adesive non possono essere utilizzate nella gestione dei tripidi sulla cipolla, ma solo per il monitoraggio dei tripidi.…

Taschenbuch. Condición: Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - Using different sampling methods is helpful in the survey of insect fauna of onion and to provide an understanding of onion thrips, Thrips tabaci in relation to cultivars and biotic and abiotic factors. Thirty six insects and spiders belonging to 17 families and 10 orders are associated with onion cultivars. Early detection and monitoring of T. tabaci could be done by using sticky trap or plant sampling. Abiotic factors (temperature and relative humidity) are the major influencing factors that regulate the population growth. Natural enemies and other insect pests of onion are non-significantly related with T. tabaci in field condition. Blue sticky trap and plant sampling are the best methods to determine the level of infestation. Economic threshold level could be determined by sticky traps, but it needs more investigation. Sticky traps could not be used in the management of thrips on onion crop but only for monitoring thrips. …
