Clip Cages for Plant - Insect or Pathogen Interactions

This frame-less clip cage is used to contain small insects like small pests such as whiteflies (Bemisia sp.), aphids (Aphis sp.) and mites (Urticae sp.) on host plants. It is constructed of 150 x 150 mesh or 160um opening or 0.16mm openings. Smallest possible insect can be accommodated by this mesh. The foam rings are placed on each side of the subject leaf under investigation. They are held in place by three splayed staples (as shown in the picture) that are inserted in the appropriate positions of each ring. The angled shape of the staple serves to clamp the rings snugly against the leaf. Four staples are supplied with each cage.

The color of the foam ring might change between white and grey to a dark grey color.

Price listed is for each of the clip cages and minimum order to be made is 12 units.


Several entomological studies needed small or area-confined cages to assess the plant-insect or pathogen interactions. Few such studies can be designed are;


a. Study of modes of action of an bioactive or chemical active compounds. The clip cages can be used to cordon off a section of an area, release insects of interest and study effects after few days. This way we can figure out which plant part is most responding to challenged treating by confining insects to that part.

b. Rearing insects in situ on live plant parts in the natural environs. Can be known affects of changed weather conditions on breeding efficiency or sustainability of insects under a particular climate. For example to study biological parameters relating to fitness, development, fecundity and mortality rates, competitiveness against other insects, coin habitant ability of different insects etc.

c. Feeding preference of insects. By releasing and confining insects in different plant parts it can be assessed most vulnerable plant part against a particular insect species

d. Most vulnerable plant part to get infection against plant pathogens especially the pathogens that transmit through vectors

d. Most vulnerable plant part to get an infection. Clip cages can hold the infected vector species against a particular plant part. This study will facilitate most vulnerable plant part or region for infection

e. Study ETL levels and compare damages under greenhouse and natural environmental conditions

f. Deep analysis of plant tolerance and plant resistance. For example, if a plant variety has shown resistance to pest attack it is generally analysed that the plant variety is resistant. However, it is sometime important that which plant part is conferring that defined defense. Using no-choice cages, the insects can be kept confined to a part and assess the insect ability to grow naturally on that plant part. By studying different plant parts with confined study of insects, can be able to check if leaves (top or bottom portion), stem, buds, flowers are conferring maximum resistance.


We have three models of clip cages available to study these aspects. These are for studying different insects like small pests such as whiteflies (Bemisia sp.), aphids (Aphis sp.) Jassids, Bettles and mites (Urticae sp.)

1. 65 x inner dimension of 50 x with a height of 10 mm. Each of the clip cage sandwiches is provided with 6 units of clips for tight clipping the cage to reduce the escapees


2. Each ring has an outside dimension of 1-7/16″, inside dimension of 1″ and thickness of 3/8″ (40 x 25.4 x 9.5 mm)


3. Each ring has an outside dimension 60 x inner dimension of 40 x with a height of 10 mm
