“…The probability of host counter by C. flavipes is influenced by factors such as the host range of parasitoid, the availability of the susceptible host stage and the mortality rate at oviposition and between host encounters. Parasites (egg parasitoids: T. chilonis, Telenomus dignus and larval parasitoid, C. flavipes) were recorded parsitise eggs (4.26 to 25.08 %) and larvae (4 to 14.27%) of internode borer (Gupta 1954, Kalra and Srivastava 1966, Easwaramoorthy and Nandagopal 1986. The trials conducted earlier revealed that reduction of incidence of internode borer by release of egg parasitoid, Trichogramma chilonis and larval parasitoid, C. flavipes (Sithanantham et al, 1973;Varma, 2002 andTiwari et al, 1996).…”

“…The more destructive amongst these borers are those attacking the sugarcane stem (Gupta, 1960). Internode borer, Chilo sachariphagus indicus and stalk borer, Chilo auricilius are one of the major destructive borers distributed in all cane growing states in peninsular and subtropical India, respectively (Agrawal, 1964, David et al, 1979, Easwaramoorthy and Nandagopal, 1986, Srikant and Kurup, 2011. These borers are limiting factors in increasing sugarcane production and insecticides play a significant role in containing borers.…”

parasitoid, Trichogramma chilonis, larval parasitiod, Cotesia flavipes and pupal parasitoid, Tetrastichus howardi against sugarcane internode and stalk borer in RBD with a plot size of 72sq.m. The incidence of internode borer ranged from 2.34 to 4.91% in treated plot as compared to control (7.87%) in August, however during October incidence ranged from 2.14 to 6.86%.At harvest, minimum incidence of internode borer (5.62%) was observed in T. chilonis followed by C. flavipes (7.52%) released plots. The released parasitoids are more active in the field for its parasitisation and multiplication which result a reduction in the incidence of INB in released plots where as beyond October the prevailing low temperature, appeared to be non-conductive for its mating and field parasitisation. The incidence of stalk borer during August and October was low (1.03- 5.54%). At harvest minimum incidence (5.55%) was observed in C. flavipes followed by T. howardi release plots (10.92%) as against 17.24% in control. Removal of dry leaves and late shoots was observed to reduce the damage by migratory borer larvae in August and October. The results indicates that parasitoids (egg, larva and pupal) play a significant role in the management of INB and SB to check the spread and lowering the incidence of this pests. It is suggested that a working of these parasitoids can be exploited in programmes for management of sugarcane stalk and internode borer.

“…Internode hardness, fiber, and pith did not show strong relationship with borer incidence in the present study though in an earlier study with progeny from a cross, internode rind hardness and fiber were more closely associated with resistance than pith (White et al, 2006). Higher infestation in loose sheath-clasp varieties suggested their suitability since tight leaf sheath is known to act as an adverse barrier for initial establishment of neonate larvae (Easwaramoorthy and Nandagopal 1986), and it may also render leaf axils inaccessible for pupation. Such a trend was noticed earlier with the borer even in S. barberi clones (Mahesh et al, 2018).…”

A four-year field study (2013–2016) was conducted to screen Indian sugarcane hybrids together with two susceptible checks against internode borer Chilo sacchariphagus indicus (Kapur) (Lepidoptera: Crambidae) in endemic locations of Tamil Nadu State, India. Each year, borer incidence on cane basis and intensity on internode basis were assessed at harvest to eliminate susceptible entries. Of the total 535 hybrids screened, only Co 293 emerged as resistant at the end of fourth year trial which was confirmed in tests under controlled conditions with artificial infestation. A modified relative resistance ratio computed using incidence and intensity also confirmed its resistance to the borer. In laboratory oviposition choice tests with excised leaves of the resistant Co 293 and susceptible hybrids Co 86032 and Co 1060, percent of leaf bits oviposited, egg masses laid, and egg numbers deposited were significantly lowest in Co 293. Also, an oviposition preference index computed for both egg mass number and egg number was significantly lowest for Co 293 which suggested antixenosis. Larval survival was significantly lowest in Co 293 with 5 to 10-fold higher neonate mortality than in the two susceptible hybrids. Prolonged larval development period and lower fecundity were observed when the borer was reared on Co 293 which indicated antibiosis. A relative suitability ratio developed from larval and pupal durations also indicated lower suitability of Co 293. Among the plant morphological characters examined, leaf length and cane thickness positively influenced borer incidence; loose sheath-clasp was associated with higher borer incidence. Among 12 shoot phenolics quantified, eight were present in higher quantities in Co 293 suggesting their role in antibiosis. Co 293 identified as resistant hybrid in the present study has the potential to be used as a parent in breeding programs for C. sacchariphagus indicus resistance.

“…The rice crops has infested by several Lepidopteran stem borer (SB) species like yellow stem borer (YSB), Scirpophaga incertulas (Walker) (Chakraborty and Deb, 2008) [21] , Pink stem borer (PSB) Sesamia inference (Walker) (Rajesh et al, 2018) [75] , Dark headed stem borer (DSB) Chilo polychrysus (Walker) (Neupane, 1990) [64] , Stripped stem borer (SSB) Chilo suppressalis (Walker) (Easwaramoorthy and Nandagopal, 1986) [41] . The SBs are key group of insect pests of rice and they have shown geographical variation in its species composition.…”

“…In PSB, S. inference, approximate generation time (T c ) were found higher in alternative host maize than in sugarcane, whereas intrinsic rate of natural increase (r m ), finite rate of increase (λ), gross reproduction rate (GRR), net reproduction rate (NRR) were higher in alternate host sugarcane than in maize (Sedighi et al, 2016) [85] . By analyzing the life table data of rice pests in different host and agro-climatic condition type-III survivorship obtained in S. incertulas (Dutta and Roy, 2018) [39] , type IV exhibited by C. suppressalis (Easwaramoorthy and Nandagopal, 1986) [40] and C. polychrysus (Alghali, 1988) [8] . By studying population dynamics, first instar larva of S. incertulas (Mukunthan, 1989) [63] , C. suppressalis (Koyama, 1977) [55] have identified most vulnerable stages.…”

Rice (Oryza sativa L.) is used as staple food for the overwhelming majority of the world's population. Rice production hampered mostly by stem borers like, yellow stem borer (Scirpophaga incertulas) pink stem borer (Sesamia inference), dark headed stem borer (Chilo polychrysus), stripped stem borer (Chilo suppressalis). For minimize the infestation farmers use different resistant rice cultivars like,
