Liying Li

This autobiography documents the life and accomplishments of Li Liying. Born into a poor family in China, she eventually became director of Guangdong Entomological Institute. After graduating middle school (1949), she was admitted to the Agronomy Faculty at Beijing Agricultural University but was shortly after redirected by the Chinese Government to Timiryazev Agricultural Academy, Moscow, Russia. The last year of her study at Timiryazev Agricultural Academy was a pivotal experience. She had the opportunity to conduct fieldwork on cotton pest control and became aware of the harmful practice of aerially spraying highly toxic organophosphates with workers present. She decided to dedicate herself to finding safer alternatives and became a leader in the development of mass-rearing techniques for insects beneficial to agriculture. She traveled to laboratories in several foreign countries to foster collaboration and exchange of ideas among colleagues. She is recognized for her service to entomological societies, teaching at universities, and love of entomology.

Aims: In this paper Cotton Pest App is designed to identify the leaf disease in cotton at early stage. Cotton Pest App is an innovative application that is useful for farmers. Methodology: The farmers can capture the images in the cotton field and upload the images. Cotton API is created and placed in cloud services. Images taken from farmers field matches with Cotton API and gets the TNAU recommendation for the cotton leaf diseases. Results: Cotton Pest App for pest management in cotton will analyze and provide an accurate recommendation to farmers about the type of pesticide for the symptoms given through the images. Conclusion: This paper expresses the idea about the creation of Cotton Pest App, an android application that helps to make management decision for cotton leaf symptoms. The study would provide a better understanding of the management practice required for the cotton leaf disease.

A two-sex life table is a useful tool for studying the fitness of predators. Previous studies of Orius strigicollis Poppius (Heteroptera: Anthocoridae) fitness have not been done on Pectinophora gossypiella (Lepidoptera: Gelechiidae) using a two-sex life table tool. This study reports the fitness of the minute predatory flower bug, O. strigicollis when feeding on the cotton pest P. gossypiella using a two-sex life table tool. Different densities (5, 10, and 15 eggs) of P. gossypiella eggs were used to calculate the feeding capacity and fitness of O. strigicollis in the laboratory at 28 °C ± 1, 75 ± 5% RH and 16:8 (L:D). The results concluded that O. strigicollis is an efficient predator of P. gossypiella. The maximum growth capacity of the predatory bug O. strigicollis was attained when it was fed on 10 and 15 P. gossypiella eggs. Furthermore, shorter generation and development time were also observed in the case of 15 eggs of P. gossypiella. These results suggest that O. strigicollis has considerable predatory potential and prefers feeding on P. gossypiella eggs than on the first instar larvae at the fourth instar or the female stage. Although the field potential of O. strigicollis is still unknown, this study will support future investigations in terms of field applications.
