Abstract

Mealybug is an important pest of papaya plants. Induction of plant resistance using elicitors, such as salicylic acid, might have the potency to reduce the extent of crop damage by mealybug. Therefore, a laboratory experiment was performed to determine the effect of salicylic acid on feeding preference, fecundity, oviposition period, and longevity of papaya mealybug adult, Paracoccus marginatus. The results showed that the application of salicylic acid increased total phenol content on papaya leaf (r = 0.57) hence decreased in feeding preferences and fecundity, slowed down the growth period of the nymph and pre-oviposition period, and prolonged the longevity of mealybug. The potency of using salicylic acid to control of mealybug on papaya in integrated pest management was discussed in this paper.

Abstract

The field schools in Indonesia employ an extension alternative model that is considered appropriate to change the habits and behavior of farmers to make them IPM experts in their field. This study was conducted to understand the behavior (knowledge and attitude) of farmers who have joined field schools, i.e. Integrated Pest Management Farmers Field School (IPM-FFS) and Landscape Integrated Pest Management (Landscape IPM), toward the use of pesticides in Klaten, Central Java, Indonesia. The research used a survey method with purposively selected respondents comprising 55 farmers of the IPM alumni and 25 farmers of the Landscape IPM alumni. A descriptive analysis was conducted to analyze the farmers’ knowledge and attitude toward the use of pesticides. Mann-Whitney U-test analysis was performed using Statistical Product and Service Solution (SPSS) version 23, to compare the knowledge and attitude of farmers regarding the use of pesticides. The results showed that the knowledge of farmers of  the Landscape IPM alumni regarding the use of pesticides was higher than that of farmers of the IPM-FFS alumni. There was no difference in the behavior of farmers between the IPM-FFS alumni and the Landscape IPM alumni regarding their attitude toward the use of pesticides.
