Prevalensi cendawan entomopatogenik, Neozygites fumosa (Speare) Remaudie’re & Keller (Zygomycetes: Entomophthorales) pada populasi kutu putih, Paracoccus marginatus Williams & Granara De Willink (Hemiptera: Pseudococcidae) di wilayah Bogor Anik Nurhayati; Ruly Anwar

The prevalence of entomopathogenic fungus, Neozygites fumosa (Zygomycetes: Entomo-phthorales) on the papaya mealybug, Paracoccus marginatus (Hemiptera: Pseudococcidae), was studied in Bogor in two districts: Bubulak and Rancabungur in 2011. Thirty plants of either papaya or cassavas were sampled 8 times, once a week for insect population and biweekly for the fungus infection sampling. The results showed that the cassava mealybug was not found on both plants and all locations. The populations of papaya mealybug in Bubulak were higher than in Rancabungur. The populations of papaya mealybug on papaya were higher than those of cassava. However, N. fumosa infection levels on both plants and both locations were not significantly different.

Paracoccus marginatus Williams & Granara de Willink (Hemiptera: Pseudococcidae) is one of the papaya insect pests that causes high economic loss. The major constraint in controling this pest with insecticides is the existence of wax layer covering the insect body.The objective of this research was to evaluate the effectiveness of Piper retrofractum (Pr), Anonna squamosa (As), and Tephrosia vogelii (Tv) extracts as well as their mixtures to control P. marginatus imago in the laboratory. Pr, As, and Tv extracts were tested separately and in extract mixtures against female P. marginatus by direct spray on the insect. Each treatment was observed at 24, 48, and 72 hours after treatment (HAT). Our result showed that at the LC95 – 72 HAT, Tv and As extracts were about three times more effective to P. marginatus than Pr extract. The effective concentration that causing around 95% mortality of P. marginatus are 1.250% (Tv), 1.482% (Pr), dan 0.469% (As). Extracts mixtures of Tv + As (2:1, w/w) and As + Ps (2 : 1, w/w) were about 1.67 times more effective than Tv + Pr (2:1, w/w) extracts mixtures. Based on combination index at 72 HST, extract mixtures of Tv + As and Tv + Pr had low sinergistic joint action, meanwhile As + Pr extract mixture had additive joint action. In addition, all the extracts treatments disturbed the formation of the wax coverings the eggs (egg sacs). Pr, As, and Tv extracts as well as their mixtures at certain extract comparison have the alternate potential to control the mealybug P. marginatus.

Thrips parvispinus Karny (Thysanoptera: Thripidae) is one of the major pests of chili pepper in Indonesia. The pest can be found on all parts of the plants, especially flowers and leaves. Information of the biology and demographic statistic of T. parvispinus are still limited. The objective of this research was to study the biology and demographic statistic of T. parvispinus in Bogor. Fifty individual of 1st instar nymphs were reared on caged chili pepper leaves (d = 4 cm and h = 8 cm). Chilli pepper leaves were replaced everyday and observed daily to determine the development and number of offspring eggs. The collected data were used to obtain information about the biology of the pest such as the stadia of each instar, preoviposition period, life cycle, adult longevity, and fecundity. The data were also used to construct life tables for demographic statistic analysis using of the Jackknife method. There were 5 phases of immature stages of T. parvispinus: eggs, two instars nymph, prepupa, and pupa with their stadia were 4,79, 1,36, 3,54, 1,08, and 1,96 days respectively. The preoviposition period of the insect was 1,11 days, life cycle was 13,68 days, female longevity was 8,55 days, male longevity was 6,00 days, and fecundity was 15,33 eggs per female. The population development of T. parvispinus followed type III of survivorship curve with intrinsic rate of increase was 0,15 individual per days female per days, net reproductive rate was 5,71 individual per female per generation, generation time was 11,49 days and doubling time was 4,57 days.

The yellow stem borer, Scirpophaga incertulas (Walker) is a major nocturnal pest of rice. Presence of S. incertulas moth had a flight peak during the lunar period and affects its reproductive status. The purpose of this study was to analyze the critical time in the lunar period related to the highest reproductive status of S. incertulas in the field. Monitoring of moth populations were carried out by setting up two traps equipped with 60-watt LED lights (800 lm) on farmers’s fields in Rawamerta District, Karawang Regency, West Java. Moth trapping was carried out once an hour, started 6–10 PM, for three days on lunar period. The observation were conducted during the nursery, maximum tillering, and grain filling phases. upen capture, females were transferred to rearing cages until they laid all their eggs. Moth reproductive status, fecundity, and fertility were counted and analyzed. Total of captured female S. incertulas moths in the lunar period from three phases of rice was 216 individuals. In the nursery phase, the highest population level was obtained at 8 PM at 27.8%, While the maximum tillering and grain filling phase were 39.3 and 29.1% at 7 PM. The highest population level of virgin, mating, and post-oviposition moths was obtained at 7 PM, at 10,94, 12,52, and 9,64%. The highest average fecundity occurred at 6 PM with 42 eggs/group and the highest fertility was 45,8% at 8 PM. The highest critical reproductive time of female S. incertulas moths occured between 6–8 PM.
