Eocanthecona furcellata (Wolff.) (Hemiptera: Pentatomidae) is an important predator for several agriculturally important pests. The biology of E. furcellata has been done with several insect pests but there is no report on the laboratory host, Corcyra cephalonica (Stainton). Hence, this study is aimed to understand the biology of E. furcellata Wolff. and its role in mass rearing on laboratory reared pest C. cephalonica Stainton. The analyses showed that the total number of eggs of the predatory stink bug was 44±8 days, incubation period 6±1.05days and the life cycle passed through five nymphal instars with a total nymphal period of about 16±0.64days. Male and female longevity were 12±1.05days and 14±1.09days, respectively, and total longivity period for male and female lasted 32±0.19 and 36+1.90days, respectively. Moreover, this study revealed that C. cephalonica could be used as alternative host to mass rear E. furcellata when the main host is not available.

EFFECT OF DIFFERENT INSECT HOSTS ON BIOLOGY AND PREDATION EFFICIENCY OF EOCANTHECONA FURCELLATA WOLFF (HEMIPTERA: PENTATOMIDAE)2017 •
Eocanthecona furcellata (Wolff.) (Hemiptera: Pentatomidae) is an important predator for several agriculturally important insect pests. Laboratory experiments were conducted to find out the impact of different lepidopteran hosts on the biology and predation efficiency of E. furcellata. The analyses showed that minimum life period (31.33±0.57 days) of E. furcellata was recorded on larvae of Corcyra cephalonica with lowest no. of egg laying (32.33±3.05 eggs) followed by 37.33±3.21 days on Maruca virata with 43.66±4.72 eggs and longest life span (39.33±2.30 days) was recorded on Spodoptera litura with maximum egg lay of 58.00±5.29 eggs. The maximum 85.94% predation was recorded on larvae of M. vitrata followed by 84.49% on larvae of C. Cephalonica. Results revealed that M. vitrata, S. litura and C. cepahlonica were found to be suitable host and larvae of Spilarctia obliqua was not reported as preferred host of the E. furcellata. There fore, E. furcellata could be utilised effectively against M. vitrata under field conditions, moreover, S. litura and C. cephalonica could be employed as laboratory hosts for mass rearing of E. furcellata.

Effect of live and freeze killed larvae of preffered hosts on the biological attributes of predatory bug, E. furcellata2021 •
Pentatomid predatory bug, Eocanthecona furcellata is a potential predator which effectively controls different lepidopteran pests of various crop ecosystems. Hence, proper utilization of this predator in biological control of insect pests is the need of the hour. In this regard, experiment was conducted to study the suitability of freeze killed larvae of Spodoptera litura and Corcyra cephalonica for mass rearing of E. furcellata based on different biological attributes. The total adult period of predator on live larvae varied significantly with frozen larvae of both the prey. The maximum consumption rate of adult predatory bug was recorded on freeze killed larvae of S. litura while minimum consumption rate was observed on live larvae of C. cephalonica. The results revealed that E. furcellata can be successfully reared on the live and frozen larvae of both the prey in laboratory conditions. Therefore, live and freeze killed larvae of S. litura and C. cephalonica may be exploited for mass rearing of predatory bug in laboratory conditions.

Comparative biology of two congeneric stinkbugs, Chinavia impicticornis and C. ubica (Hemiptera: Pentatomidae)2015 •
The objective of this work was to compare the biology of Chinavia impicticornis and C. ubica (Hemiptera: Pentatomidae), two species of stinkbugs that occur as secondary pests in soybean. Life table procedures were used for evaluating nymphs, and fecundity tables for evaluating adults, in order to establish the demographics of the two species. The two species have similar demographic parameters, and the development of immature stages, from egg to adult, had similar duration periods of approximately 30 days. In both species, eggs and second-instar nymphs were the stages with higher mortality. Total egg production did not differ between females of both species. Fecundity and survival curves for adults showed similar trends in both species. However, C. ubica had greater potential to increase its populations, since its fecundity parameters were significantly higher than those of C. impicticornis. Moreover, the generational time and the time required to double the population size were sho...

Predation and parasitism of naturally occurring and sentinel stink bug egg masses of Halyomorpha halys (Stål) and Nezara viridula (L.) (Hemiptera: Pentatomidae) in various southeastern habitatsStink bugs, including Halyomorpha halys (Stål) and Nezara viridula (L.), are agricultural pests that feed on fruit in a variety of crops. Monitoring predation and parasitism of stink bug egg masses furthers our understanding of potential biological control tactics. However, best practices for laboratory and field assessments of parasitism and predation of egg masses require further attention. We carried out a series of laboratory and field experiments to test whether parasitism and predation for three types of sentinel H. halys egg masses, fresh, frozen, and refrigerated, varied in agricultural commodities. In addition, we asked if predation and parasitism differed between sentinel and naturally occurring H. halys and N. viridula egg masses in soybean. In the laboratory, more H. halys eggs were parasitized by Trissolcus euschisti (Ashmead) (Hymenoptera: Scelionidae) if they were frozen or refrigerated compared to fresh eggs. Similarly, in the field, parasitism was higher for frozen ...

Effect of Egg Rearing Temperature and Storage Time on the Biological Characteristics of the Predatory Stink Bug <I>Podisus nigrispinus</I> (Hemiptera: Pentatomidae)2008 •
Maize and rice constitute some of the most important cereals cultivated in the world, being used as staple food for people especially in Africa. The rice moth, Corcyra cephalonica, and the maize weevil, Sitophilus zeamais, are major pests of stored grains in the tropics. The use of parasitoids in biological pest control is already common in different agricultural and horticultural fields. At present, grain managers tend to look at alternatives to chemicals to control insects in stored grain. Lariophagus distinguendus (Förster) is a synovigenic, solitary larval and pupal ectoparasitoid of several beetle species that infest stored goods. The ability for long-range host finding of this parasitoid mediated by volatiles has been shown (Steidle & Schöller 1997). Habrobracon hebetor (Say) is a gregarious ectoparasitoid of many lepidopterous pests. This wasp occurs naturally in the stored grain ecosystem (Keever & al. 1985) where it attacks several pyralid moths, including the rice moth, Co...
