“…It has the potential to penetrate leaf tissues by translaminar movement and it has been recommended for controlling tomato leaf miners in many countries such as Algeria [33] and Greece [5]. Invasive alien species causes a high degree of loss in crop productivity, and it is difficult to control [34], it should be managed carefully from infected land to maximize productivity and to limit the spreading and invasion to other land [35] Steinernema sp. (B32) and Heterorhabiditis sp.…”

Tuta absoluta (Meyrick) (Lepidoptera: Gelechiidae) is an invasive alien species especially infested tomato crops. It invaded Egypt in 2009 and many plantations. It's difficult to control due to the limitation of insecticides, therefore, the susceptibility of T. absoluta to three indigenous isolates of entomopathogenic nematodes in Egypt, i. e. Heterorhabditis bacteriophora (EKB20), Steinernema sp. (B32) and Heterorhabiditis sp. (Kasassien isolate) were determined in the laboratory, greenhouse, and field experimental compared with emamectin benzoate insecticide. Leaf bioassays were carried out to evaluate the affinity of nematode isolates to reach the larvae and affect them at the galleries. The efficacy of the three nematode species after foliar application to potted tomato plants was evaluated under laboratory conditions. High larval mortality (70.6-94%) and low pupae mortality (<25%) were determined. In the leaf bioassay tests, a high level of larval infestation (75.4-88.6%) indicated the nematode's ability to kill the larvae within the galleries compared with 100% mortality of emamectin benzoate with the recommended dose. In the pot experiments treatment plants with nematode caused a reduction in insect infestation by 87-94% compared with 96% in the treatment of emamectin benzoate. The results of the field experiment showed the efficiency of entomopathogenic nematodes for reducing infestation with T. absoluta with 70 to 90 % reduction % compared with more than 95% with emamectin benzoate. The results suggested that EPN are considered promising biocontrol agents, if correctly applied and released in integrated control schemes against the tomato leaf miners T. absoluta.

Ethnofarming Practices of Mandaya Ginger Farmers in Andap, New Bataan, Davao de Oro, Philippines

The study aimed to determine the socio-demographic profile and document existing practices and problems related to ginger farmers' soil fertility, diseases, and insect pest management practices. Also, to analyze the agro-ecological situation using SWOT analysis. The enumerators conducted one-on-one interviews with the ginger farmers with participative field transects from November 2017 to June 2018 to identify the Ethnofarming practices of Mandaya ginger farmers with 44 key participants. The result shows that the majority of the ginger farmers are old (36%), male (80%), married (85%) with 5 to 6 children (32%), with more than 25 years of ginger farming experience (77%) in less than 0.25 hectare (50%), and have low educational attainment (48%). The Mandaya ginger farmers use soil color and texture, the presence of Ageratum conyzoides, and crop income from the previous cropping as indicators to identify fertile and infertile soils. Fewer Mandaya farmers still practice indigenous knowledge including magical, factual, and traditional practices on ginger production. Although most farmers use new technologies, some tend to combine their indigenous knowledge with new technologies for ginger farming. It has been identified that the Mandaya farmers had limited knowledge of controlling insect and disease infestations, soil fertility management, and commodity price fluctuation, which are significant constraints for them. Mandaya ginger farmers and government agencies are encouraged to develop technologies that will utilize their indigenous knowledge of ginger and other crops while promoting, preserving, and protecting their cultural identity anchored to a scientific way of farming to help attain food security and sustainability for the country.
