An understanding of the role of factors intrinsic to a species' life history in structuring contemporary genetic variation is a fundamental, but understudied, aspect of evolutionary biology. Here, we assessed the influence of the propensity to outbreak in shaping worldwide genetic variation in Locusta migratoria, a cosmopolitan pest well known for its expression of density-dependent phase polyphenism. We scored 14 microsatellites in nine subspecies from 25 populations distributed over most of the species' range in regions that vary in the historical frequency and extent of their outbreaks. We rejected the hypothesis that L. migratoria consists of two genetically distinct clusters adapted to habitats either rarely (nonoutbreaking) or cyclically (outbreaking) favourable to increases in population density. We also invalidated the current subspecific taxonomic classification based on morphometrics. Bayesian inferences indicated evidence of a homogenizing effect of outbreaks on L. migratoria population structure. Geographical and ecological barriers to gene flow in conjunction with historical events can also explain the observed patterns. By systematically assessing the effects of null alleles using computer simulations, we also provide a template for the analysis of microsatellite data sets characterized by a high prevalence of null alleles.

“…These swarms are increasing either as a result of particular weather conditions or of anthropogenic changes of the environment (e.g. Lecoq & Sukirno 1999). Nine geographical taxa of L. migratoria with different propension to display outbreaks were described and considered as subspecies (review in COPR 1982).…”

Because of the scarcity of polymorphic genetic markers available in locust species, only a few population genetics studies have been carried out on this taxon. We isolated and characterized 11 polymorphic microsatellite loci in the pest locust Locusta migratoria capito, and described experimental conditions for polymerase chain reaction (PCR) multiplexing and simultaneously genotyping these loci. The number of alleles per locus ranged from six to 25, and the expected heterozygosity ranged from 0.431 to 0.957. Results of cross‐taxon amplification tests are reported in six other Locusta migratoria subspecies, six species of the Oedipodinae subfamily and two other pest locust species.

“…Dibandingkan dengan perlakuan kontrol yang tidak diberi pupuk hayati. Jumlah belalang pada pengamtan ke tiga meningkat dikarenakan belalang yang semula hanya beberapa menjadi sebuah kelompok yang besar, seperti yang dikemukkan oleh (Kalshoven, 1981;Lecoq, 1999;Sosromarsono, 1998) mengemukakan bahwa Belalang diketahui mempunyai tiga fase populasi yang sangat khas. Yang pertama adalah fasepsoliter, yaitu ketika belalang kembara berada dalam populasi rendah di suatug hamparanh sehingga mereka cenderung mempunyai perilaku individual.…”

This study is entitled Study of Biofertilizer Types of Grasshopper Pest Intensity on Black Corn (Black Aztec) with the aim to study the types of biological fertilizer on grasshopper pest intensity. which began on November 9, 2019, in Jembangan Hamlet, Gagaksipat Village, Ngemplak District, Boyolali District, Central Java, with a height of 150m (asl). This research uses factorial basic design complete randomized block design (RCBD) arranged in a single factor consisting of 10 treatments 3 replications. From the results of this study were analyzed with the Dancun multiple range test (Duncan Multiple Range Test / DMRT) at a level of 5%. Observations observed included: symptoms of attack, intensity of attacks, fresh weight of cob with skin, fresh weight of stover, weight of 100 seeds. The results of the research show that: (1) Symptoms of locust pest attacks appear evenly on Biotogrow biofertilizers, symptoms of pest attacks begin to appear at the age of 20 days after planting. (2) The treatment of biological fertilizers affects the intensity of pest attacks on maize plants with the highest Biotogrow biofertilizers namely 22.6 and the lowest attacks on Megarizho fertilizers namely 13.8. (3) Megarizho biological fertilizer treatment can reduce locust pest attack,.
