In the dynamic world of gardening , the struggle against pests is ongoing and ever - evolving . At the recent Rio Breakfast during the International Horticulture Trade Fair ( IPM ) in Essen ( DE ) , a spotlight was cast on the pervasive issue of Thrips parvispinus . This pestis has been troubling growers since its European detection in 2001 . Cristina Prados Fernández , a expert specialiser from Koppert , took the stage to partake in her expertise on integrate blighter direction ( IPM ) strategy orient to battle this resilient plague .
Koppert , a loss leader in the kingdom of biologic ascendency and pollenation , boasting a 2021 turnover of $ 300 million , operates 11 product centers and apply a workforce of 2,750 . Their approach to pest direction is about controlling and understand the pest itself .
Cristina explained that Thrips parvispinus , start from Indonesia , acquaint alone challenge due to its varied host range , distinctive forcible characteristics , and procreative behavior . This pest was first detected in Europe in Greece in 2001 on Gardenia . The symptoms are principally visible on tender parting and stem next to bud . The terms these Thrips can cause varies between feeding damage , scrubby development , flower and fruit damage , and a reduction in photosynthesis and it can be a transmitter for industrial plant diseases .
Thrips parvispinus can be differentiated from other thripid by the antennaes which are bicolored and with stripes of unlike thicknesses , in contrast to other thripid having stripes of the same thickness . The male reading is pale while the female person is black / brown . The wheel to adult is 14 to 16 day at a relative humidity of 65 % and temperature of 20 - 25 point . Another feature is that they can be hosted by 40 different plant specie , from Abelmoschus to Zea Mays .
Cristina outlined the necessity of a holistic Integrated Pest Management ( IPM ) scheme , that includes chemic , biologic , ecosystem , physical , and technical methods . She highlighted the grandness of biological ascendence as a fundament of IPM , discussing various lifelike enemies of Thrips parvispinus , from predatory mites to entomopathogenic fungi and nematode .
This list of ' instinctive enemies ' was established based on thorough research in which the next parametric quantity were evaluated :
• birth rate of the females• Predation : rate of feeding• Ability to locate the pest• Survival with exclusive diet thrips• Supplementary feeding• Formats / acid / repetition / date of introduction• Development of Modern auxiliary and Modern lotion techniques formatsCrucial tips to fight against thrips parvispinus:• Eliminate the remaining plants from the last production• Pinch to eliminate the damage part of the plant and the thrips on it together• found a quarantine zona for all the initial material• Establish a robust monitoring system to observe and mark areas pretend by Thrips• ensure there is plenty of nourishment for the auxiliaries• Alternate the entomopathogenic Nematodes• Plan an initial treatment in summer• Plan Chemical treatments in December , this will help to deoxidise the population
