Pengaruh Waktu Pemasangan Kerodong pada Buah Pisang terhadap Serangan Hama Nacoleia Octasema

Abstract

<p>Bagging banana fruits can be develop as a control to protect the fruits from Nacoleia octasema. The objective of this research was to determine the effect and relation of the banana fruit bagging time on N. octasema. This research was conducted in Tlogo Orchard, Delik Village, Tuntang District, Salatiga, Central Java from September-November 2018. This research used purposive sampling with 3 banana cultivars and 4 treatment. The observation variable of this research was the incidence of attacks. The results showed that there was an effect on the banana fruit bagging time against the incidence of pest attacks. The average incidence attack showed that the unbagged banana fruits had the biggest attacks. In addition, there was a positive relationship between the banana fruit bagging time and cultivars on the incidence of attacks. The older a banana bagged, the greater incidence of pest attacks. Kepok had the biggest incidence of attacks compared to the other cultivars.</p>

SERANGAN HAMA KUDIS PISANG Nacoleia octasema Meyr (LEPIDOPTERA: PYRALIDAE) PADA BEBERAPA KULTIVAR PISANG

“…Larva menggerek bunga dan kulit buah pisang muda yang masih tertutup seludang bunga (Tsatsia & Jackson 2017), sehingga menimbulkan luka pada permukaan kulit pisang yang menyebabkan perkembangan buah terhambat, kulit tampak burik, kasar, dan keras (Kalshoven 1981). Upaya pengendalian N. octasema yang dilakukan saat ini adalah dengan insektisida (Balitbangtan 2008, Wahyudi et al 2018, Tsatsia & Jackson 2017 dan pengerodongan tandan pisang dengan plastik (Anandita et al 2019;Khamid et al 2016), namun masih belum memberikan hasil yang memuaskan.…”

Effect of installation time and mesh size of fruit wrapping to scab symptoms on Cavendish banana

“…The lowest average attack happened on wrapping before flowering, while the highest was on fruit wrapping 14 days after flowering. Attacks by N. octasema still occur in the wrapping installation before flowering because the female moths have laid eggs on the banana heart [8]. The size of the mesh and the wrapping material can also affect the intensity of N. octasema attacks on bananas due to differences in humidity generated by each type of material [9].…”
