BIO-EFFICACY OF NEWER INSECTICIDES AGAINST BLISTER BEETLE AND POD SUCKING BUG IN PIGEONPEA (CAJANUS CAJAN L. MILLSP.)

Plant Archives
A field experiment was conducted during the kharif season of 2022 at the Agricultural Research Farm ofB.R.D. P.G. College, Deoria (U.P.) to evaluate the bio-efficacy of newer insecticides against blisterbeetle (Mylabris pustulata Thunberg) and pod sucking bug (Clavigralla gibbosa Spinola) infestingpigeonpea (Cajanus cajan (L.) Millsp.).

Infestation of Soybean with Two Species of Pod-Sucking Bugs

International Journal of Tropical Insect Science, 1994
Experiments on artificial infestation of soybean with pod-sucking bugs showed that Riptortus dentipes caused more damage to the plant than did Nezara viridula . The density of four insects per plant used was high enough to significantly damage the plant.

Tough Pod Wall: A Factor Involved in Cowpea Resistance to Pod Sucking Bugs

International Journal of Tropical Insect Science, 1988
Six cowpea cultivars, TVu 1890, TVu 1, TVx 3343-03E, IT82E-9, VITA-3 and Ife Brown, with different responses to infestation and damage by pod-sucking bugs (PSBs) were studied for the biophysical and biochemical characteristics of pod that may be involved in this differential response to feeding by PSBs.

Damage by pod‐sucking bugs on cowpea when intercropped with maize

Tropical Pest Management, 1991
Abstract Agroecosystems in the tropics include growing two or more crops in diverse polycultural patterns. In Kenya, cowpea Vigna unguiculata (Walp.) is grown in combination with cereals such as maize and sorghum, perennial legumes such as pigeon peas and root crops such as cassava and sweet potatoes.

Resistance Level of Soybean Genotypes against Pod Sucking Bug (Riptortus linearis F. Hemiptera: Alydidae)

LEGUME RESEARCH - AN INTERNATIONAL JOURNAL, 2023
Background: Pod sucking bug (Riptortus linearis F. Hemiptera: Alydidae) is one of the major insect pest in soybean that cause yield loss up to 79%. This study was carried out to identify the level of resistance to pod sucking bug on soybean genotypes. Methods: Field research was conducted at Muneng Experimental Farm, Probolinggo, East Java, Indonesia ...

Interaction between pod age and position on damage to cowpea Vigna unguiculata by hemipteran pod-sucking bugs

Bulletin of Entomological Research, 2001
AbstractLaboratory and screenhouse studies were carried out to assess the relationship between pod age and pod position of cowpea and damage by different pod bug species. The coreids Clavigralla tomentosicollis Stäl and Riptortus dentipesFabricius caused significant damage to young pods of cultivated genotypes, in contrast to the coreid Anoplocnemis ...

Cowpea Antixenosis to the Pod Sucking Bug, Clavigralla Tomentosicollis Stal. (Hemiptera: Coreidae)

International Journal of Tropical Insect Science, 1991
Seven cowpea cultivars and a susceptible and two resistant checks were evaluated for their preference by Clavigralla tomentosicollis for oviposition and feeding under free-choice condition in the screenhouse and under no-choice in mesh cages. Female bugs had no distinct ovipositional preference for any of the test cultivars than the susceptible check ...

Field Infestation and Damage to Soybean and Cowpea by Pod-Sucking Bugs in Benue State, Nigeria

International Journal of Tropical Insect Science, 1992
Soybean, Glycine max (L.) Merril, andcowpea, Vigna unguiculata (L.) Walp., were grown in field plots in 1988 and 1989 to compare infestation and damage by pod-sucking bugs (PSBs). Population of PSB was monitored by counting adults and nymphs on rows two and six of each plot from 5 to 14 weeks after planting.
