These assessments served as the basis for developing a proper action program. The assessments took place in Banyubiru Sub-District, Semarang District covering four villages (Kebondowo, Rowoboni, Tegaron, Kebumen) in December 2013. We analyzed BPH data, along with information about farmers’ practices in managing pests collected through interviews conducted in January 2018 in Indramayu. Additionally, we examined data on the number of BPH-infested areas in Java from 2010 to 2020 and the stock of insecticides in Java in 2021. Simple statistical analyses were carried out. The BPH population had spread throughout Banyubiru and was present in all sampled plots. The average number of BPH eggs ranged from 115.25 to 379.65 per rice hill, while the BPH nymphs and imagoes ranged from 3.42 to 11.87 per rice hill. The relatively low nymphs to imagoes ratio might be influenced by the high BPH predator populations, which ranged from three to six individuals per rice hill. Suspected causes of BPH resistance and resurgence included the application of banned and improper insecticides, as well as the repeated use of the same insecticide active ingredients for an extended period. It is recommended to discontinue the mass spraying of insecticides to prevent further plant damage. In 2022, the Pest Control Movement has suggested replacing chemical insecticides with biological or natural pesticides. Intensive extension programs are strongly needed.","PeriodicalId":31609,"journal":{"name":"Jurnal Entomologi Indonesia","volume":"102 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135616565","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

H. talaca can cause losses of between 40–100% in the dry season if proper control is not carried out. H. talaca has natural enemies such as predators, parasitoids, and pathogens. One of the entomopathogens is NPV. This study aims to obtain molecular characteristics through DNA polymerase sequences and determine the virulence level of NPV isolates from H. talaca. The same species from different locations can have genetic variability. Therefore, molecular characterization by polymerase chain reaction (PCR) on DNA polymerase sequences is one way to study the genetics of HytaNPV. NPV was isolated from infected H. talaca larvae collected from the field. The DNA isolates were used as templates for PCR for DNA polymerase gene amplification with an amplicon target of ±1,000 bp. A sequencing process followed the PCR provides nucleotide sequence. HytaNPV DNA polymerase sequencing results were aligned with GenBank’s BLAST data to provide information on the relationship of HytaNPV to NPVs isolated from other regions. Based on molecular character analysis using DNA polymerase gene sequence, HytaNPV Bogor has a homology level of 93.9% with HytaNPV isolated from India. HytaNPV Bogor has a genetic relationship with the NPV that infects Buzura suppressaria from China and Australia. HytaNPV Bogor is similar to the NPV that infects H. talaca from India.

This study aims to analyze the foraging behavior of O. smaragdina in two different habitats, namely urban and non-urban. The two locations are characterized by differences in the intensity of human interaction and the distance between the trees and the tree canopy. The behavioral observation method uses all sampling events with five behavioral categories: lurking (M1), approaching (M2), carrying (M3), communicating between ants in a colony (K1), and competition with other ants (K2). We tested three different types of feed: chick scraps, Tenebrio molitor Linnaeus larvae, and sugar. The results showed that there were three sequences of foraging behavior in urban areas, namely: (1) M1, M2, K1, M3, (2) M1, M2, K1, M3, K2, and (3) M1, M2, K2, M3. Meanwhile, there is only one pattern in non-urban areas, namely M1, M2, M3. Approaching food (M2) and lurking food (M1) were the dominant responses of O. smaragdina in urban and non-urban areas. In urban areas, broiler chickens were the type of feed most approached by ants, followed by sugar and beetle larvae. O. smaragdina in non-urban areas also preferred chicken pieces as feed compared to the others, but only one individual O. smaragdina approached (M2) chicken pieces and none approached the others. Foraging ants are more active at high temperature and low humidity, compared to low temperature and high humidity.

We conducted these trials at 74 locations, non-replicated, across Java, in the wet and dry seasons of 2020–2021 where YSB are endemic and problematic. Efficacy of MD in pheromone foundational practice (PFP) was compared to conventional grower practice (CGP). Trap reduction, a measure of MD was significantly higher (>70%) in PFP as compared to CGP. A major benefit of MD is reduction in damage. Significantly lower damage to rice tillers (40–46%) was seen in PFP compared to CGP. Lower damage in PFP likely protected yield by 0.43 to 0.76 ton/ha compared to CGP. Compared to PFP, CGP required 40–56% higher insecticide applications to manage YSB.

In this study, specimens from three different locations (Bandung, Sumedang, and Purworejo) and specimens from the Museum Zoologicum Bogoriense (MZB) were examined. A total of 31 individuals from five different species were analyzed based on their morphological features. The data collected was coded and analyzed using cladistic methods, and the results were used to create cladogram trees for each of the five species i.e., Phimenes flavopictus, Polistes stigma, Apodynerus troglodytes, Vespa affinis, and Vespa velutina, showing their biogeographical distribution. The cladistic analysis in this study showed the relationships between the different species based on their morphological characteristics. The arrangements of the clades were determined using the Euclidean method in R studio. The results showed that P. flavopictus has two clades based on the marking patterns on their thorax and abdomen, while the other species i.e., Po. stigma, V. affinis, V. velutina, and A. troglodytes have three clades based on their coloring and marking patterns on all segments.

This research was conducted to determine the effect of intercropping pattern of honey pumpkin plants with several repellent plants on percentage of infestation, population of A. saltator larvae/pupae, and honey pumpkin production. This study was designed with a randomized block design (RBD) consisting of 4 treatments, namely: honey pumpkin plants monoculture (A); intercropping of honey pumpkin and lemon grass plants (B); intercropping of honey pumpkin and turmeric plants (C); intercropping of honey pumpkin and spring onion plants (D). Each treatment was repeated 6 times. The results show that; the average percentage of infestation by A. saltator until 56 days after planting (DAP) for all treatments ranged from 72–79.6%. The population of A. saltator larvae/pupae ranged from 107–128 individuals/9 plants. Honey pumpkin production ranged from 21.97–26.75 kg/9 plants. From the results it was concluded that turmeric, lemon grass, and spring onions had no effect on the percentage of infestation of A. saltator populations, and honey pumpkin production.","PeriodicalId":31609,"journal":{"name":"Jurnal Entomologi Indonesia","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-07-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47329748","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
