การใช้ราในการควบคุมปริมาณเพลี้ยกระโดดสีน้ำตาลศัตรูข้าว Nilaparvata lugens

เชื้อราจำนวน 15 สกุล แยกได้จากเพลี้ยกระโดดสีน้ำตาลที่เป็นโรค ซึ่งรวบรวมจากศูนย์วิจัยข้าวปทุมธานี เมื่อทดสอบเชื้อราที่พบบ่อยครั้งและ/หรือเชื้อราที่มีรายงานว่าเป็นเชื้อราสาเหตุโรคของแมลง จากผลการทดลองพบว่าเชื้อรา Metarhizium flavoviride 1 สายพันธุ์ และเชื้อรา Paecilomyces fumosoroseus 1 สายพันธุ์ ทำให้อัตราการตายสะสมของแมลงสูงกว่าชุดควบคุมอย่างมีนัยสำคัญ

Flight fuels in the brown planthopper Nilaparvata lugens

Journal of Insect Physiology, 1983
Abstract The flight fuels of Nilaparvata are a combination of carbohydrate and lipid. In insects of constant age, lipid deposits are proportional to body weight, as is the rate of utilisation of lipid in flight. Reserves of glycogen are more variable and show no correlation with body weight. They are also always extremely low, approximately 0.2% of

[Chaotic diagnosis of Nilaparvata lugens occurrence system].

Ying yong sheng tai xue bao = The journal of applied ecology, 2004
It is estimated that there are nearly 20 million hectares of rice crop being infested by Nilaparvata lugens, with an annual loss of some half a million tones of grain. In order to study the properties and laws of Nilaparvata lugens occurrence system further, the time series data of Nilaparvata lugens occurrence from 1986 to 1998 collected in Taihu Lake

Functions of keratin-associated protein genes in reproduction of Nilaparvata lugens

Journal of Insect Physiology
As a notorious rice pest, Nilaparvata lugens (Stål) (Hemiptera: Delphacidae) inflicts severe damage owing to its exceptionally high reproductive potential. Previous ovarian transcriptome analyses have revealed that the insect Keratin-associated protein (KAP) gene is potentially implicated in vitelline secretion and eggshell sclerotization, and it holds
