Bed bugs are considered a major public health problem in industrialized countries. Usually, bed bug infestations are managed using a combination of physical and chemical methods. In recent years, new strategies for bed bug control have emerged, particularly the use of dusts like diatomaceous earth and silicon dioxide. However, in Europe, the use of silicon dioxide is restricted to professional, while diatomaceous earth can be harmful to the lungs. This study aimed to assess bed bug mortality rates associated with Sommières earth, green clay, talc, and sodium bicarbonate compared to silicon dioxide and diatomaceous earth from a pest management company, diatomaceous earth for litter conditioner, and diatomaceous earth from a supermarket. We tested permanent exposure, short exposure, horizontal transfer and repellent effect on two bed bug colonies. Sommières earth demonstrated efficacy ranging from 75% to 100% in permanent and short exposures, similar to the efficacy of diatomaceous earth from the pest management company. On the contrary, diatomaceous earth for litter conditioner and diatomaceous earth from a supermarket, green clay, talc, and sodium bicarbonate were found to be ineffective. This study demonstrates, for the first time, the efficacy of Sommières earth against bed bugs, but also highlights the variability in efficacy of diatomaceous earths on bed bugs depending on their quality.

“…In recent times, pyrethroids and natural oils have been found to be effective for management of bed bugs 14,15 . But it is very challenging to control the infestations because of their cryptic behaviour and high adaptability to various physical and chemical controlling paradigms that sometimes leads to develop resistance to the speci c class of compound 6,16,17 .…”

Emerging infestations of bed bugs are affecting normal human lifestyles globally. To perform a scientific experiment, there is a paramount requirement for an established rearing condition. Thus, this study has been conducted to optimize and establish the rearing conditions for bud bugs (Cimex lectularius L.) based upon temperature and relative humidity. The bed bugs have been projected onto three temperatures (20 ºC, 25 ºC, and 30 ºC) and relative humidity (50%, 70%, and 90%) conditions to check their overall growth and survival rate. Adult mortality, weight loss, egg laying, percentage egg hatching, hatching initiation and completion, nymph mortality, and molting have been evaluated to optimize the best rearing conditions. The temperature at 25 ºC with 90% RH showed minimum mortality for adults (female 13.33±3.33% and male 6.67±3.33%) and nymphs (13.33±3.33%), maximum egg laying (40.33±1.86), and percentage hatching (98.23±0.58%). Moreover, at 30ºC with 90% RH, both hatching initiation and completion (5.19±0.12 days and 7.23±0.16 days) as well as molting initiation and completion (3.73±0.12 days and 7.00±0.24 days) were found to be fastest. Thus, it can be concluded that 25 °C with 90% RH is ideal for the rearing of adults, while 30 °C with 90% RH will be appropriate for their overall development.

Emerging infestations of bed bugs are affecting normal human lifestyle globally. This study has been designed to optimize the rearing conditions for Cimex lectularius L. (Hemiptera), to support the scientific research on them. Bed bugs have been projected onto three different temperature (20 °C, 25 °C, and 30 °C) and relative humidity (50%, 70%, and 90%) conditions to check their overall growth and survival rate. Adult mortality, weight loss, egg laying, percentage hatching, hatching initiation and completion, nymph mortality, and molting have been evaluated to optimize the best conditions. The temperature at 25 °C with 90% RH showed minimum mortality for adults (female 13.33 ± 3.33% and male 6.67 ± 3.33%) and nymphs (13.33 ± 3.33%), while maximum egg laying (40.33 ± 1.86), with highest percentage hatching (98.23 ± 0.58%). At 30 °C with 90% RH, hatching initiation and completion (5.19 ± 0.12 days and 7.23 ± 0.16 days) as well as molting initiation and completion (3.73 ± 0.12 days and 7.00 ± 0.24 days) were found to be fastest. Thus, it can be concluded that 25 °C with 90% RH is ideal for rearing of adults and 30 °C with 90% RH is appropriate for rapid growth of nymphs.
