Bioesai bioinsektisida Beauveria bassiana dari Sumatera Selatan terhadap kutu putih pepaya, Paracoccus marginatus Williams & Granara De Willink (Hemiptera: Pseudococcidae)

In fresh swamp areas of South Sumatra, papaya mealybug,<em> Paracoccus marginatus</em> (Hemiptera: Pseudococcidae) could cause severe damage to young papaya trees and decreased the fruit quality. The objective of this research was to bioassay test of the bioinsecticide <em>Beauveri...

The objective of this research was to bioassay test of the bioinsecticide <em>Beauveria bassiana</em> againts nymphs of<em> P. marginatus</em>. <em>B. bassiana</em> was conducted on rice medium. The bioinsecticide was formulated using dried compost, compost gram, paddy ash, paddy bran, woody powder, paddy bran mixed with woody powder, compost enriched with <em>Trichoderma virens</em>. Controls used were sterile water (control 1) and isolate of <em>B. bassiana</em> (control 2). Results showed that conidial viability of<em> B. bassiana</em> on control 2 was the highest (46.33%). The viability of control 2 was not significantly different from the formulations with carrier of the paddy bran, the paddy bran mixed with woody powder, and the compost enriched with <em>T. virens.</em> The highest nymph mortality (82.86%) was found on formulation of compost enriched with<em> T. virens</em> and was significantly different from other treatments.

Mortality on control 1 on average was 29.52%, whereas control 2 averaged of 75.71%. The shortest median lethal time (LT50) (3.55 days) was found on formulation of compost enriched with <em>T. virens</em> but the longest one (3.73 days) occured on the formulation of paddy ash.
