在玉米丛矮性植物原体（MBSP）的媒介Dalbulus madis (DeLong & Wolcott)（半翅目：蝉科）的病理系统中，植物原体在媒介体内的传代、入侵和繁殖过程中发生的相互作用是从其他病理系统中归纳出来的，但对具体的相互作用知之甚少。为了了解MBSP的运动及其与载体的潜在特异性相互作用，研究人员解剖了被感染者（获取期为4 d，潜伏期为23 d）和未被感染者的肠道和唾液腺。用透射电镜对器官进行可视化处理。在病媒的消化道、肠系膜上皮、血肿和唾液腺中观察到植物原体细胞的图像，并通过观察具有晚期疾病症状的玉米根中的类似细胞来证实。对MBSP在其载体内运动的研究显示了MBSP植物原体与麦蚜之间协同作用的新发现。
In the pathosystem of Dalbulus madis (DeLong & Wolcott) (Hemiptera: Cicadellidae), a vector of maize bushy stunt phytoplasma (MBSP), the interactions occurring during the passage, invasion, and multiplication of the phytoplasma inside the vector body have been generalized from other pathosystems, with a poor understanding of the specific interactions. With the aim to understand MBSP movement and potential specific interactions with its vector, D. maidis adults were dissected to obtain the intestine and salivary gland of both infected (acquisition access period = 4 d; latent period = 23 d) and noninfected individuals. The organs were processed for visualization with transmission electronic microscopy. Images of phytoplasma cells were observed in the alimentary canal, epithelium of the mesenteron, hemocele, and salivary gland of the vector, and were confirmed through observation of similar cells in maize roots with advanced disease symptoms. The study of the MBSP movement within its vector shows novel findings between the synergy of the MBSP phytoplasma and D. maidis.
