“…They have always been source of serious damage to crop by feeding on developing cotton balls, and ripened cotton seeds. Both nymph and adults of the genus Dysdercus have strong proboscis, a needle like stylet meant for piercing and sucking of plant sap [1,2,3] . They are the destructive pest of cotton due to severe lint staining problem [4,5,6,7,8,9,10] .…”

An attempt was made under laboratory condition to estimate the functional response of fourth instar of R. fuscipes to different prey densities (1, 2, 4, 8 and 16) of D. koenigii. Fourth instar of this predator showed a curve linear functional response against first nymph of D. koenigii. The prey consumed ratio (y) of R. fuscipes was increased as the D. koenigii densities(x) increases from one D. koenigii/ R. fuscipes to 16 D. koenigii / R. fuscipes. The maximum predation rate was restricted to the maximum D. koenigii number (3.9). The predation attack ratio (y/x) at less prey density categories was highest. Searching time (Ts) and attack ratio (y/x) were decreased with the increasing prey density. The fourth instar of R. fuscipes showed curve linear functional response curve when offered with different prey densities. The killing efficiency was higher at nymphal stage.

“…A wide range of chemical groups of pesticides such as organochlorines, organophosphates, carbamates, pyrethroids, avermectins, spinosyns and neonicotinoids etc., have been used in the fields (Saeed et al, 2018). Toxicity of chlorpyrifos, deltamethrin, lufenuron, flucycloxuron (andalin), chlorfenpyr and thiamethoxam has been demonstrated against D. koenigii (Khan & Qamar, 2011;Saeed, Naqqash, & Jaleel, 2016;Jameel & Jamal, 2017). Despite control attempts and studies with diverse chemicals and alternate measures to chemicals, pyrethroids are still preferred because of their efficacy at low dosages and relative safety (Mohd, Nasreen, Snigdha, & Altaf, 2021).…”

Dysdercus koenigii is a major global pest of cotton that causes severe economic loss. Among several control measures, pyrethroids are frequently used toxicants because of high efficacy at low dosages and relative safety. Since haemocytes are biomarkers of the physiological response and immunity of insect which determine the insecticide efficacy, the current study assessed the effect of a pyrethroid, β-cyfluthrin, on the total and differential haemocyte counts of D. koenigii. Haemolymph was collected from the fifth instars after the topical application of β-cyfluthrin (0.8, 1.6, 3.2, 6.4 and 12.8 mg/L) on the thoracic tergum. The haemolymph of control nymphs revealed 5270 haemocytes/mm3 which decreased instantly by 1.4-3.1-fold on β-cyfluthrin exposure; more reduction observed at lower dosages. Increase in exposure duration and β-cyfluthrin dosages fluctuated the count considerably, eventually raising them at lower dosages and diminishing at higher dosages. Among five kinds of haemocytes recorded in the haemolymph, the β-cyfluthrin exposure increased %prohaemocytes count; diminished %granulocytes and %plasmatocytes count while spherulocyte and oenocyte counts were inconsistent. The alterations in haemocyte counts indicate the immunity response trigger in D. koenigii due to β-cyfluthrin-induced stress. Further investigations may decipher the mechanisms involved and help to formulate the strategies for its management in fields.

“…The red cotton bug, Dysdercus koenigii F. (Hemiptera: Pyrrhocoridae), is one of the pests of cotton in Pakistan and other cotton growing areas of the world. It feeds on mature cotton seeds, cotton bolls and causes staining in the cotton lint (Shah, 2014; Sprenkel, 2000). Nymphal instars and adults suck the sap by upward and downward movement of proboscis in the cotton bolls (Shah et al ., 2016).…”

Under natural environmental conditions, insects are highly affected by heat stress. Studies on the effect of heat stresses on the life history of Dysdercus koenigii are scarce. This study investigated the effect of short-term high temperature stress on the developmental period, survival rate of all stages and reproduction of D. koenigii adults. Eggs, nymphs and adults were exposed to 28 °C, 31 °C, 34 °C, 37 °C and 40 °C for 2 h and returned to the laboratory to check all the above-mentioned aspects. The developmental duration and survival rate of all stages decreased with the increase of temperature. Longevity and survival rate of females were significantly higher than males after exposure to heat. Fecundity and hatching percentage was significantly decreased with the increase of temperature. Because short-term high temperature stress response is vital for the survival of all stages of D. koenigii, our findings can be used to develop a more profound understanding of the potential for this insect to evolve in response to environmental changes.
