chui inside Langcuo Lake along with the utilization reputation involving existing inhabitants assets based on the Beverton-Holt energetic comprehensive model. The final results showed that Gary. chui have been mainly made up of people aged 2 to 20 a long time throughout Langcuo Body of water, with a length-body excess weight romantic relationship situation associated with W=0.0105L3.042. The von Bertalanffy development picture said the sea food acquired the asymptotic body length of L∞=37.28 centimetres, expansion coefficient of k=0.160, and also theoretical development commencing chronilogical age of t0=-0.887 a new. The complete death coefficient Z was approximated because 2.48, in line with the length-converted get necessities technique. Based on Pauly’s test formulation, natural mortality coefficient Michael ended up being 3.34, fishing death coefficient F has been 3.15, and exploitation charge Elizabeth was 2.Twenty nine selleck compound , showing that H. chui resources in Langcuo Lake are not over-exploited. Taking into consideration the Bio-mathematical models growth and also death regarding Gary. chui inside Langcuo Body of water, doing some fishing is correct, having a recommended sportfishing length of Lc=22.37 centimetres.All of us reviewed the results of low temperature on ovum hatching and eliminating charge with the Next instars of Meloi-dogyne incognita (J2) within the lab. We all further evaluated the end results of two dirt treatments on the rate of survival regarding Michael. incognita in n . The far east inside a field try things out. The outcomes regarding research laboratory research showed that survival rate of J2 has been 0 soon after being exposed to -7 ℃ for 24 hours, knowning that egg cell hatching had been completely inhibited A day soon after becoming put through -9 ℃. The actual survival rate of J2 had been Zero after staying subjected to -1, -2, -3, and also -4 ℃ with regard to 8-10, Five, Three, and also A single.5 deb, respectively. Eggs hatching was completely restricted after staying afflicted by -2, -3, -4, and -5 ℃ with regard to Being unfaithful, Six, 4, along with A single deb, correspondingly. Connection between the particular fitted analysis showed that both the associations between the temp and also the dangerous duration of J2 as well as the heat as well as the non-hatching use of the particular ovum followed dramatical functions. The results involving industry examination demonstrated that death charge associated with Michael. incognita inside 0-50 cm garden soil level right after ridging treatment and also 0-30 centimetres soil coating after questing treatment method may get to 100%, while the illness list with the previous throughout 30-40 centimeters and 40-50 cm was 84.9% as well as Seventy five.8%, correspondingly, which has been below that in the greenhouse. Our own benefits declare that protecting against and also controlling Michael. incognita within inside gardens by means of low-tempe-rature during winter might achieve a far better control effect throughout Yulin City along with the northward place. Your offered technique is hassle-free and possesses extragenital infection substantial possibility of popularization.To reveal the end results involving nitrogen (D) advices as well as mowing around the plethora and abundance involving pest local community in field steppe, we investigated the large quantity and variety associated with herbivorous insects below 4 treatments in Interior Mongolia meadow steppe throughout August 2022, including manage, D addition, mowing, as well as mixed And supplement and also trimming.
